Only 9 of 50 operated rats lived 33 months. Breast tumors developed in 10 control rats but in none given shoyu. The distribution of other tumors was the same,... and concluded that Shoyu did not appear to be a carcinogen in the rat; its prolonged use impaired neither health nor longevity. Long-term use was associated with gastric mucus loss and nuclear changes in a few rats, occasionally with a mild gastritis. according to "Long-term effect of shoyu (Japanese soy sauce) on the gastric mucosa of the rat" by MacDonald WC, Dueck JW.(4)
5. Hypolipidemic effect
In the observation of Soy sauce (Shoyu), a traditional Japanese fermented seasoning and its effect on cholesterol level found that in a 4-week randomized, double-blind, placebo-controlled parallel group study, hyperlipidemic men (TG >150 mg/dl) were treated with 600 mg of SPS (n=15) or placebo (n=15) daily. After 4 weeks, serum TG levels in the SPS-treated group were significantly (P<0.05) lower than the baseline (0 week). In conclusion, SPS of soy sauce reduce lipid absorption, and soy sauce is a potentially promising seasoning for the treatment of hyperlipidemia through food, according to "Hypolipidemic effect of Shoyu polysaccharides from soy sauce in animals and humans" by Kobayashi M, Magishi N, Matsushita H, Hashimoto T, Fujimoto M, Suzuki M, Tsuji K, Saito M, Inoue E, Yoshikawa Y, Matsuura T.(e)

C. Quoted from Phytochemicals in Foods
Daidzein is a phytochemical in the Isoflavones,
belonging to the group of Flavonoids (polyphenols), found abundantly in
food of the family of legumes, soy, alfalfa sprouts, red clover,
chickpeas, peanuts, etc.
1. Breast cancerIn the investigation of the anticancer effects and cellular apoptosis pathways induced by daidzein, using human MCF-7 breast cancer cell line, found that daidzein-induced ROS generation was accompanied by disruption of mitochondrial transmembrane potential, down-regulation of bcl-2, and up-regulation of bax, which led to the release of cytochrome C from the mitochondria into the cytosol, which, in turn, resulted in the activation of caspase-9 and caspase-7, and ultimately in cell death, The induction of the mitochondrial caspase-dependent pathway was confirmed by pretreatment with pan-caspase inhibitor z-VAD-fmk and antioxidant N-acetyl-L-cysteine, according to "Daidzein induces MCF-7 breast cancer cell apoptosis via the mitochondrial pathway" by Jin S, Zhang QY, Kang XM, Wang JX, Zhao WH.(1)
2. Ameliorative effect
In
the investigation of Estrogen deficiency was produced in female
Sprague-Dawley rats by surgical removal of both the ovaries and these
animals were used 4 weeks later and observation of Endothelium-dependent
and endothelium-independent relaxations due to acetylcholine and
sodium nitroprusside, found that Administration of daidzein (0.2
mgkg(-1)day(-1), sc 0.4 mgkg(-1)day(-1), sc and 0.8 mgkg(-1)day(-1), sc)
and Atorvastatin (30 mgkg(-1)day(-1), po Positive Control) for one
week markedly improved vascular endothelial dysfunction due to increase
in nitric oxide bioavailability perhaps by inhibiting caveolin-1 and
activation of PI3K-AKT pathway, according to 'Ameliorative effect of daidzein: a caveolin-1 inhibitor in vascular endothelium dysfunction induced by ovariectomy" by Sharma S, Singh M, Sharma PL.(2)
3. Prostate cancer
In
evaluation of a mixture of soy isoflavones (genistein, daidzein,
glycitein) and theirs effect on Prostate cancer, found that Daidzein
could be the component of soy that protects against genistein-induced
metastasis. Daidzein inhibited cell growth and synergized with
radiation, affecting APE1/Ref-1, NF-kappaB and HIF-1alpha, but at lower
levels than genistein and soy, in AR+ and AR- PCa cells, suggesting it
is an AR-independent mechanism, according to "Daidzein effect
on hormone refractory prostate cancer in vitro and in vivo compared to
genistein and soy extract: potentiation of radiotherapy" by Singh-Gupta V, Zhang H, Yunker CK, Ahmad Z, Zwier D, Sarkar FH, Hillman GG.(3)
4. Cellular Integrity
In
the investigation of the protective effect of two major soy
isoflavones, genistein and daidzein, in combination on the status of
glycoconjugates in plasma, found that Oral administration of genistein +
daidzein (20 mg + 20 mg kg(-1) bw/day) to DMBA treated rats
significantly (p< 0.05) brought back the status of glycoconjugates to
near normal range. The present study thus demonstrated that genistein
and daidzein in combination, according to "Genistein and
Daidzein, in Combination, Protect Cellular Integrity during
7,12-Dimethylbenz[a]anthracene (DMBA) Induced Mammary Carcinogenesis in

flavonoids of C. spatholobi (SSCE), according to '[Study on HPLC chromatographic fingerprint of anti-tumor active site SSCE of Caulis spatholobi].[Article in Chinese]" by Wang H, Liu Y, Zeng Z, He W.(5)
6. Endometrial cancer
In
the evaluation of Legume, soy, tofu, and isoflavone intake and
endometrial cancer risk in postmenopausal women, found that reduced risk
of endometrial cancer was associated with total isoflavone intake
(highest vs lowest quintile, ≥7.82 vs <1.59 mg per 1000 kcal/d, RR =
0.66, 95% CI = 0.47 to 0.91), daidzein intake (highest vs lowest
quintile, ≥3.54 vs <0.70 mg per 1000 kcal/d, RR = 0.64, 95% CI = 0.46
to 0.90), and genistein intake (highest vs lowest quintile, ≥3.40 vs
<0.69 mg per 1000 kcal/d, RR = 0.66, 95% CI = 0.47 to 0.91). No
statistically significant association with endometrial cancer risk was
observed for increasing intake of legumes, soy, tofu, or glycitein,
according to "Legume, soy, tofu, and isoflavone intake and endometrial
cancer risk in postmenopausal women in the multiethnic cohort study" by
Ollberding NJ, Lim U, Wilkens LR, Setiawan VW, Shvetsov YB, Henderson
BE, Kolonel LN, Goodman MT.(6)7. Anti-allergic activities
In the investigation of the biocatalytic synthesis of xylooligosaccharides of daidzein, using cultured cells of Catharanthus roseus and Aspergillus sp. β-xylosidase, found that The cultured cells of C. roseus converted daidzein into its 4'-O-β-glucoside, 7-O-β-glucoside, and 7-O-β-primeveroside, which was a new compound. The 7-O-β-primeveroside of daidzein was further xylosylated by Aspergillus sp. β-xylosidase to daidzein trisaccharide, i.e., 7-O-[6-O-(4-O-(β-d-xylopyranosyl))-β-d-xylopyranosyl]-β-d-glucopyranoside, which was a new compound. The 4'-O-β-glucoside, 7-O-β-glucoside, and 7-O-β-primeveroside of daidzein exerted DPPH free-radical scavenging and superoxide radical scavenging activity. On the other hand, 7-O-β-glucoside and 7-O-β-primeveroside of daidzein showed inhibitory effects on IgE antibody production, according to "Synthesis of xylooligosaccharides of daidzein and their anti-oxidant and anti-allergic activities" by Shimoda K, Hamada H, Hamada H.(7)
8. Menopausal symptoms
In the examination of the efficacy of a supplement containing natural S-(-)equol, a daidzein metabolite, in reducing menopausal symptoms, found that the beneficial effects of a 10-mg natural S-(-)equol supplement is consumed daily for 12 weeks on major menopausal symptoms, specifically, hot flushes and neck or shoulder muscle stiffness, in postmenopausal Japanese women. This supplement offers a promising alternative for management of menopausal symptoms, according to "A natural s-equol supplement alleviates hot flushes and other menopausal symptoms in equol nonproducing postmenopausal Japanese women" by Aso T, Uchiyama S, Matsumura Y, Taguchi M, Nozaki M, Takamatsu K, Ishizuka B, Kubota T, Mizunuma H, Ohta H.(8)
9. Anti skin aging
In the explanation of Oestrogen (17β estradiol) and the dietary antioxidants resveratrol, genistein and S-equol, an isoflavone produced from the gut biotransformation of soy daidzein, are effective agents to reduce ageing in skin, indicated that the evidence to date suggests that the primary mechanism of action of these antioxidants is to activate oestrogen receptor β (ERβ), which in turn enhances the expression of antioxidant enzymes and inhibits the expression of snail, a transcription factor that regulates keratinocyte cell proliferation and migration. Based on their selectivity, ERβ agents provide a treatment option for ageing skin without the potential safety issues associated with oestrogen therapy, according to "Ageing skin: oestrogen receptor β agonists offer an approach to change the outcome" by Jackson RL, Greiwe JS, Schwen RJ.(9)
10. Cardioprotective effect
In the investigation of the involvement of caveolin in attenuation of the cardioprotective effect of IPC during DM in rat, found that attenuation of the cardioprotection in diabetic heart may be due to decrease the IPC mediated release of NO in the diabetic myocardium, which may be due to up -regulation of caveolin and subsequently decreased activity of eNOS, according to "Possible involvement of caveolin in attenuation of cardioprotective effect of ischemic preconditioning in diabetic rat heart" by Ajmani P, Yadav HN, Singh M, Sharma PL.(10)
11. Bone density
In the observation of the association between habitual phyto-oestrogen intake and broadband ultrasound attenuation (BUA) of the calcanaeum as a marker of bone density, found that enterolignans and equol were positively associated with bone density in postmenopausal women, but this association became non-significant when dietary Ca was added to the model. In the lowest quintile of Ca intake, soya isoflavones were positively associated with bone density in postmenopausal women (β = 1·4; P < 0·1). The present results therefore suggest that non-soya isoflavones are associated with bone density independent of Ca, whereas the association with soya or soya isoflavones is affected by dietary Ca, according to "Association between dietary phyto-oestrogens and bone density in men and postmenopausal women" by Kuhnle GG, Ward HA, Vogiatzoglou A, Luben RN, Mulligan A, Wareham NJ, Forouhi NG, Khaw KT.(11)

Genistein is a phytochemical in the Isoflavones, belonging to the group of Flavonoids (polyphenols), found abundantly in food of the family of legumes, soy, alfalfa sprouts, red clover, chickpeas, peanuts, etc.
1. Bladder Cancer
In a phase 2 randomized, placebo-controlled trial investigated whether daily, oral genistein (300 or 600 mg/day as the purified soy extract G-2535) for 14-21 days before surgery alters molecular pathways in bladder epithelial tissue in 59 subjects diagnosed with urothelial bladder cancer (median age 71), found that G-2535 treatment was well tolerated; observed toxicities were primarily mild to moderate gastrointestinal or metabolic and usually not attributed to study drug. Genistein was detected in plasma and urine of subjects receiving G-2535 at concentrations greater than placebo subjects' but were not dose-dependent. Reduction in bladder cancer tissue p-EGFR staining between the placebo arm and the combined genistein arms was significant at the protocol-specified significance level of 0.10 (p=0.07), according to "A Phase 2 Cancer Chemoprevention Biomarker Trial of Isoflavone G-2535 (Genistein) in Presurgical Bladder Cancer Patients" by Messing E, Gee JR, Saltzstein DR, Kim K, Disant'agnese PA, Kolesar J, Harris L, Faerber A, Havighurst TC, Young JM, Efros M, Getzenberg RH, Wheeler MA, Tangrea J, Parnes HL, House M, Busby JE, Hohl RJ, Bailey HH.(1)
2. Immunomodulation And Anti-Inflammation
In the review of new concepts have emerged in relation to mechanisms that contribute to the regulation of carcinogenesis processes and associated inflammatory effects, found that the effects of polyphenols on the adaptative and innate immune cells that could infiltrate the tumor. Reduction of chronic inflammation or its downstream consequences may represent a key mechanism in the fight of cancer development and polyphenols could reduce various pro-inflammatory substance productions through targeting signal transduction or through antioxidant effects, according to "Immunomodulation And Anti-Inflammatory Roles Of Polyphenols As Anticancer Agents" by Ghiringhelli F, Rébé C, Hichami A, Delmas D.(2)
3. Bone density
In the investigation of the association between habitual phyto-oestrogen intake and broadband ultrasound attenuation (BUA) of the calcanaeum as a marker of bone density, found that the non-soya isoflavones formononetin and biochanin A were marginally significant or significantly associated with BUA in postmenopausal women (β = 1·2; P < 0·1) and men (β = 1·2; P < 0·05), respectively; enterolignans and equol were positively associated with bone density in postmenopausal women, but this association became non-significant when dietary Ca was added to the model. In the lowest quintile of Ca intake, soya isoflavones were positively associated with bone density in postmenopausal women (β = 1·4; P < 0·1), according to "Association between dietary phyto-oestrogens and bone density in men and postmenopausal women" by Kuhnle GG, Ward HA, Vogiatzoglou A, Luben RN, Mulligan A, Wareham NJ, Forouhi NG, Khaw KT.(3)
4. Antioxidant effects
In the testing effects of the soy isoflavone genistein on antioxidant enzymes in DU145 prostate cancer cells, found that Genistein significantly decreased reactive oxygen species levels and induced the expression of the antioxidant enzymes manganese (Mn) superoxide dismutase (SOD) and catalase, which were associated with AMP-activated protein kinase (AMPK) and phosphatase and tensin homolog deleted from chromosome 10 (PTEN) pathways. The induced expression of catalase, MnSOD, and PTEN were attenuated by pretreatment with a pharmacological inhibitor for AMPK. Furthermore, PTEN is essential for genistein activity, as shown by PTEN transfection in PTEN-deficient PC3 cells. Thus, genistein induces antioxidant enzymes through AMPK activation and increased PTEN expression. indicating the effects of genistein primarily depend on AMPK, according to "The antioxidant effects of genistein are associated with AMP-activated protein kinase activation and PTEN induction in prostate cancer cells" by Park CE, Yun H, Lee EB, Min BI, Bae H, Choe W, Kang I, Kim SS, Ha J.(4)
5. Anti cancers
In the determination of Genistein, the predominant isoflavones found in soy, has been shown to inhibit the carcinogenesis in animal models, indicated that there are growing body of experimental evidence that show the inhibition of human cancer cells by genistein through the modulation of genes that are related to the control of cell cycle and apoptosis. Moreover, it has been shown that genistein inhibits the activation of NF-kappa B and Akt signaling pathways, both of which are known to maintain a homeostatic balance between cell survival and apoptosis. Genistein is commonly known as phytoestrogen, which targets estrogen- and androgen-mediated signaling pathways in the processes of carcinogenesis, according to "Soy isoflavones and cancer prevention" by Sarkar FH, Li Y.(5)
6. Prostate cells
In the investigation of the hypothesis that the soy-isoflavone genistein could protect DNA of LAPC-4 prostate cells from oxidative stress-related damage by enhancing the expression of antioxidative genes and proteins, found that genistein protects prostate cells from oxidative stress-related DNA damage presumably by inducing the expression of antioxidative products, such as metallothioneins. Genistein, therefore, might counteract the age-related decline of important antioxidative defence systems which in turn maintain DNA integrity, according to "Genistein protects prostate cells against hydrogen peroxide-induced DNA damage and induces expression of genes involved in the defence against oxidative stress" by Raschke M, Rowland IR, Magee PJ, Pool-Zobel BL(6)

In the investigation of the potential preventive effects of lycopene and genistein, alone and in combination, on breast cancer development in female Wistar rats treated with 7,12-dimethylbenz[a]anthracene (DMBA), a carcinogen known to induce breast tumors.
found that treatment was continued for 20 wk. Rats treated with DMBA developed mammary tumors with 100% tumor incidence during the 20-wk study. Inhibition of mammary cancer incidence by lycopene (70%), genistein (60%) and their combination (40%) was observed. Tumor weight decreased by 48%, 61%, and 67%, and mean tumor volume decreased by 18%, 35%, and 65% with lycopene, genistein, and lycopene + genistein, respectively (P < 0.01 for the combination). The proportions of adenocarcinoma masses decreased with lycopene and genistein combination (P < 0.05). Administration of lycopene and genistein combination suppressed breast cancer development and was associated with a decrease in MDA, 8-isoprostane, and 8-OhdG levels and with an increase in serum lycopene and genistein levels. Animals administered DMBA developed breast cancer, which was associated with increased expression of Bcl-2 and decreased expression of Bax, caspase 3, and caspase 9 in mammary tissues, according to "Inhibitory effects of combination of lycopene and genistein on 7,12- dimethyl benz(a)anthracene-induced breast cancer in rats" by Sahin K, Tuzcu M, Sahin N, Akdemir F, Ozercan I, Bayraktar S, Kucuk O.(7)
8. Neuroprotective effects
in the investigation of whether GEN could alleviate oxidative damage induced by beta-amyloid peptides 25-35 (Abeta25-35) in PC12 cells, found that GEN attenuated the cytotoxicity and partially prevented apoptosis induced by Abeta25-35. GEN dramatically attenuated ROS levels induced by Abeta25-35 in PC12 cells. In addition, GEN significantly reversed the reduction of MMP caused by Abeta25-35 to maintain the normal levels of the cells. The GSH/GSSG ratio in GEN pretreated groups significantly increased compared to the groups without GEN pretreatment. GEN reversed Abeta25-35 induced down regulation of the protein expression of gamma-GCS, Nrf2 and HO-1, according to "Genistein as a neuroprotective antioxidant attenuates redox imbalance induced by beta-amyloid peptides 25-35 in PC12 cells" by Ma W, Yuan L, Yu H, Ding B, Xi Y, Feng J, Xiao R.(8)
9. Anti diabetes
In the investigation of the effect of genistein on beta-cell proliferation and cellular signaling related to this effect and further determined its antidiabetic potential in insulin-deficient diabetic mice, found that genistein induced protein expression of cyclin D1, a major cell-cycle regulator essential for beta-cell growth. Dietary intake of genistein significantly improved hyperglycemia, glucose tolerance, and blood insulin levels in streptozotocin-induced diabetic mice, concomitant with improved islet beta-cell proliferation, survival, and mass. These results demonstrate that genistein may be a natural antidiabetic agent by directly modulating pancreatic beta-cell function via activation of the cAMP/PKA-dependent ERK1/2 signaling pathway, according to "Genistein induces pancreatic beta-cell proliferation through activation of multiple signaling pathways and prevents insulin-deficient diabetes in mice" by Fu Z, Zhang W, Zhen W, Lum H, Nadler J, Bassaganya-Riera J, Jia Z, Wang Y, Misra H, Liu D.(9)
10. Bone homeostasis
In the deiermination of the effect of genistein on bone homeostasis in mandibular subchondral bone of rats.Methods:Female SD rats were administered with genistein (10 and 50 mg/kg) or placebo by oral gavage for 6 weeks, found that the low and high doses of genistein significantly increased the expression of ERβ, while ERα expression was increased by the low dose genistein and decreased by the high dose genistein. ERβ silencing abrogated most of the effects of genistein treatment.Conclusion:In rat mandibular condylar subchondral bone, low-dose genistein increases bone formation and inhibit bone resorption, while excess genistein inhibits both bone formation and resorption, according to"Dose-dependent effects of genistein on bone homeostasis in rats' mandibular subchondral bone" by
Li YQ, Xing XH, Wang H, Weng XL, Yu SB, Dong GY.(10)
11. Obesity
In the study of the role of ER alpha and ER beta in a model of nutrition induced obesity, found that Treatment with E2 and Alpha decreased body weight, total cholesterol and VLDL. Visceral fat mass, adipocyte size, and serum leptin were reduced by E2, Alpha and Beta. In the soleus muscle, treatment with E2 and Beta modulated Igf1 and Pax7 gene expression and resulted in larger muscle fibers, according to "Impact of estradiol, ER subtype specific agonists and genistein on energy homeostasis in a rat model of nutrition induced obesity" by
Weigt C, Hertrampf T, Zoth N, Fritzemeier KH, Diel P.(11)
Etc.
Glycitein is a phytochemical in the Isoflavones, belonging to the group of Flavonoids (polyphenols), found abundantly in food of the family of legumes, soy, peanuts, chick peas, fava beans, alfalfa, kudzu, etc.
1. Prostate cancer
In the examination of the effects of the soy isoflavone glycitein on cellular differentiation in prostate epithelial cells (RWPE-1, WPE1-NB14, and RWPE-2), found that Glycitein significantly inhibited RWPE-1 cellular proliferation at concentrations ranging from 0.4 to 50 microM. Expression of the luminal epithelial cell marker cytokeratin 18 was not affected by glycitein treatment in the WPE1-NB14 and RWPE-2 cell line, according to "Basal cell induced differentiation of noncancerous prostate epithelial cells (RWPE-1) by glycitein" by Clubbs EA, Bomser JA(1)
2. Endometrial cancer
In the observation of the effects of Phytochemicals found in soy and other legumes in reducing the risk of endometrial cancer, found that a reduced risk of endometrial cancer was associated with total isoflavone intake (highest vs lowest quintile, ≥7.82 vs <1.59 mg per 1000 kcal/d, RR = 0.66, 95% CI = 0.47 to 0.91), daidzein intake (highest vs lowest quintile, ≥3.54 vs <0.70 mg per 1000 kcal/d, RR = 0.64, 95% CI = 0.46 to 0.90), and genistein intake (highest vs lowest quintile, ≥3.40 vs <0.69 mg per 1000 kcal/d, RR = 0.66, 95% CI = 0.47 to 0.91). No statistically significant association with endometrial cancer risk was observed for increasing intake of legumes, soy, tofu, or glycitein. Truncated age-adjusted incidence rates of endometrial cancer for the highest vs lowest quintile of total isoflavone intake were 55 vs 107 per 100 000 women per year, respectively, according to "Legume, soy, tofu, and isoflavone intake and endometrial cancer risk in postmenopausal women in the multiethnic cohort study" by Ollberding NJ, Lim U, Wilkens LR, Setiawan VW, Shvetsov YB, Henderson BE, Kolonel LN, Goodman MT.(2)
3. Ovarian cancer
In the evaluation of the impact of phytoestrogen consumption on breast cancer risk and its role on ovarian cancer, found that No statistically significant associations were found with any of the phytoestrogens under evaluation. However, there was a suggestion of an inverse association with total phytoestrogen consumption (from foods and supplements), with an odds ratio (OR) of 0.62 (95% CI: 0.38-1.00; p for trend: 0.04) for the highest vs. lowest tertile of consumption, after adjusting for reproductive covariates, age, race, education, BMI, and total energy. Further adjustment for smoking and physical activity attenuated risk estimates (OR: 0.66; 95% CI: 0.41-1.08), according to "Phytoestrogen consumption from foods and supplements and epithelial ovarian cancer risk: a population-based case control study" by Bandera EV, King M, Chandran U, Paddock LE, Rodriguez-Rodriguez L, Olson SH.(3)
4. Antioxidants
in the evaluation of the antioxidant activity and contents of various polyphenol classes in the seeds of seven soybean varieties of different seed color and one yellow seed cultivar, found that antioxidant activity of seed extracts was evaluated by the 2,2-diphenyl-1-picrylhydrazyl free radical scavenging activity assay. A positive linear correlation between antioxidant activity and contents of total polyphenols and anthocyanins was established. The highest antioxidant activity was observed in the extracts of black and brown varieties, which also showed high levels of all polyphenol classes examined. Yellow seed had the highest total isoflavone content (3.62 mg/g of dry material). The highest concentration of total daidzein was determined in black seeds (>2.0 mg/g of dry material), and the highest total glycitein and genistein contents occurred in the yellow cultivar (0.53 and 1.49 mg/g of dry material, respectively). According to our results, varieties of black and brown seeds could be of special interest not only for their large content of total polyphenols, ranging from 4.94 to 6.22 mg of gallic acid equivalents/g of dry material, but also for their high content of natural antioxidants such as anthocyanins, according to "Polyphenol content and antioxidant properties of colored soybean seeds from central europe" by Malenčić D, Cvejić J, Miladinović J.(4)
5. Cervical cancer
In the evaluation of the effect of a soy-derived isoflavone mixture (designated as SI-I, containing 71% daidzein, 14.3% genistein and 14.7% glycitein) on HeLa cells and its mechanism were investigated. SI-I in concentration range 5-80 μg/ml significantly reduced the survival rate of HeLa cells by MTT assay, found that SI-I inhibited HeLa cell growth through inducing apoptosis via the mitochondrial pathway and comparisons with reported data indicated that synergistic effect existed between the isoflavone species contained in SI-I. It is proposed that natural soy-derived isoflavones are potential candidates as chemotherapeutic agents against human cervical cancer, according to "Soy-derived isoflavones inhibit HeLa cell growth by inducing apoptosis" by Xiao JX, Huang GQ, Geng X, Qiu HW.(5)
6. Colon cancer
In the investigation of the cellular effects of soy isoflavones (composed of genistein, daidzein, and glycitein) in DLD-1 human colon adenocarcinoma cells with or without ER-β gene silencing by RNA interference (RNAi), found that maintaining the expression of ER-β is crucial in mediating the growth-suppressive effects of soy isoflavones against colon tumors. Thus upregulation of ER-β status by specific food-borne ER-ligands such as soy isoflavones could potentially be a dietary prevention or therapeutic strategy for colon cancer, according to "Estrogen receptor-β mediates the inhibition of DLD-1 human colon adenocarcinoma cells by soy isoflavones" by Bielecki A, Roberts J, Mehta R, Raju J.(6)
7. Osteoclast differentiation and apoptosis
In the investigation of the effects of glycitein on osteoclast differentiation and apoptosis in vitro,
found that Osteoclast generation was inhibited by glycitein in a biphasic-dose-dependent manner and showed the greatest inhibitory effects at 10 nM (-70%, p < 0.01). Glycitein increased caspase 3/7 activity by 15% at a concentration of 10 nM (p < 0.001). Further, 10 nM glycitein significantly decreased the expression of IL-6 (-53%, p < 0.05) and RANKL (-64%, p < 0.05) in osteoblasts but did not change mRNA levels of OPG, according to "Glycitein decreases the generation of murine osteoclasts and increases apoptosis" by Winzer M, Rauner M, Pietschmann P.(7)
8. Anti allergic effects
in the investigation of the production of beta-maltooligosaccharides of glycitein and daidzein using Lactobacillus delbrueckii and cyclodextrin glucanotransferase (CGTase) as biocatalysts,
found that The 7-O-beta-glucosides of glycitein and daidzein and 7-O-beta-maltoside of glycitein showed inhibitory effects on IgE antibody production. On the other hand, beta-glucosides of glycitein and daidzein exerted 2,2-diphenyl-1-picrylhydrazyl (DPPH) free-radical scavenging activity and supeoxide-radical scavenging activity, according to "Synthesis of beta-maltooligosaccharides of glycitein and daidzein and their anti-oxidant and anti-allergic activities" by Shimoda K, Hamada H.(8)
9. Anti-photoaging effects
In the evaluation of purified soy isoflavone extract from soybean cake for the protective effects on UVB-induced damage, Fraction 3, which contains the aglycone group (daidzein, genistein and glycitein) and acetylglucoside group (acetyldaidzin, acetylgenistin and acetylglycitin) of soy isoflavones, could inhibit UVB-induced death of human keratinocytes and reduce the level of desquamation, transepidermal water loss (TEWL), erythema and epidermal thickness in mouse skin, according to "Anti-photoaging effects of soy isoflavone extract (aglycone and acetylglucoside form) from soybean cake" by Huang CC, Hsu BY, Wu NL, Tsui WH, Lin TJ, Su CC, Hung CF.(9)
10. Hypolipidemic effects
In the comprison of whether Monascus-fermented soybean extracts (MFSE) enriched with bioactive mevinolins (natural statins) and aglycone isoflavones (daidzein, glycitein, and genistein) perform an additive hypolipidemic effect in hyperlipidemic ratsand unfermented soybean extracts (UFSE), which have a higher level of glucoside isoflavones (daidzin, glycitin, and genistin) without mevinolin, found that treatment with both MFSE200 and MFSE400 groups for 40 days significantly reduced the activities of serum aspartate aminotransferase and alanine aminotransferase by averages of 35.6 and 43.2%, respectively, as compared to the high-fat diet group (p < 0.01). The results indicate that MFSE performs a more potent hypolipidemic action via improvement of the lipid profiles and down-regulated HMG-CoA reductase activity than UFSE in hyperlipidemic rats, according to "Hypolipidemic effects of Monascus-fermented soybean extracts in rats fed a high-fat and -cholesterol diet" by Pyo YH, Seong KS.(10)
11. Metabolic and inflammatory markers
in the measurement of glucose, insulin, and adipokines/cytokines in 75 healthy postmenopausal women who were randomized to receive 20 g of soy protein with 160 mg of total isoflavones (64 mg genistein, 63 mg daidzein, and 34 mg glycitein) or 20 g of soy protein placebo for 12 weeks. Women taking estrogen discontinued therapy at least 3 months before the study, found that after 12 weeks of treatment, there were significant positive changes in tumor necrosis factor alpha levels within the placebo group (P < 0.0001) and adiponectin levels within the isoflavone group (P = 0.03). Comparison of pre-post change between the groups showed a small but significant increase in serum adiponectin levels in the isoflavone group (P = 0.03) compared with the placebo group. No significant changes were seen in any other parameter between the two groups, according to "Effects of high-dose isoflavones on metabolic and inflammatory markers in healthy postmenopausal women" by Charles C, Yuskavage J, Carlson O, John M, Tagalicud AS, Maggio M, Muller DC, Egan J, Basaria S.(11)
12. Post-menopausal effects
found that high-dose isoflavones is associated with improved QOL among women who have become menopausal recently. Hence, the timing of isoflavone supplementation with regards to the onset of menopause appears to be important. The use of isoflavones, as an alternative to estrogen therapy, may be potentially useful and seemingly safe in this group of women who are looking for relief from menopausal symptoms, according to "Effect of high-dose isoflavones on cognition, quality of life, androgens, and lipoprotein in post-menopausal women" by Basaria S, Wisniewski A, Dupree K, Bruno T, Song MY, Yao F, Ojumu A, John M, Dobs AS.(12)
13. Obesity
In the investigation of Soygerm isoflavones fermentated by Bifidobacterium breve with most of isoflavone glycosides (daidzin, glycitin and genistin) in soygerms were deglycosylated to their corresponding isoflavone aglycones (daidzein, glycitein and genistein) within 24 h fermentation, found that ral administration of fermented isoflavones effectively suppressed absorption of excessive lipid into a body. Addition of either unfermented or fermented soygerm isoflavones effectively inhibited adipocyte differentiation from 3T3-L1 in a dose dependent manner., according to "Anti-obesity activities of fermented soygerm isoflavones by Bifidobacterium breve" by Choi I, Kim Y, Park Y, Seog H, Choi H.(13)

E. Quoted From Foods to prevent and treat diseases
1. Rheumatoid Arthritis (RA)
Intake of soy protein can enhance the protective effect against Rheumatoid Arthritis. In the study to evaluate preventive and therapeutic effects of soy protein on collagen-induced arthritis rats, showed that Administration of soy protein significantly suppressed the progression of collagen II-induced arthritis and inhibited the production of tumor necrosis factor-alpha, interleukin6, leptin, and adiponectin. Soy protein appeared to be a potent immunomodulatory inhibitor of collagen II-induced arthritis in rats
(1).
2. Polymalagia Arthritis(PMR)
In the study to examine the role of TK activity on the expression of the inducible nitric oxide (NO) synthase (iNOS), found that TK inhibition by genistein had no effect on the expression or nuclear translocation of the transcription factors interferon regulatory factor-1 and nuclear factor-KB, respectively, both of which have been implicated in transcriptional regulation of the human iNOS gene. Nuclear run-on analysis demonstrated that the effect of genistein on iNOS messenger RNA expression was not at the level of transcription, suggesting that posttranscriptional regulation of iNOS messenger RNA might be TK dependent. Isoflavones, such as genistein, are useful tools to dissect regulatory pathways in vitro and in vivo and may have potential use as novel antiinflammatory therapeutic agents(2).
3. Ischemic heart disease
Soy sauce is a seasoning produced by fermenting soybeans and filamentous fungus, along with water and salt after a period of sometime, it yields a moromi or thick mash of cereal to obtain soy sauce by pressing it to liquid form. Tamari is made by collecting the liquid which was pressed and the liquid drained drains from miso after a certain time of fermentation.
a. Cardiovascular health
In the investigation of dietary proteins and their effect in heart diseases found that a direct cholesterol lowering effect of proteins has not been shown. Despite earlier research indicating that soy protein has cardioprotective effects as compared to other proteins, these observations have not been confirmed by randomized placebo-controlled trials. However, most experts recommend the consumption of foods rich in plant proteins as alternatives to meat and dairy products rich in saturated fat and containing cholesterol, according to "Dietary proteins and atherosclerosis" by Darioli R.(3)
b. Hypolipidemic effect
In the observation of Soy sauce (Shoyu), a traditional Japanese fermented seasoning and its effect on cholesterol level found that in a 4-week randomized, double-blind, placebo-controlled parallel group study, hyperlipidemic men (TG >150 mg/dl) were treated with 600 mg of SPS (n=15) or placebo (n=15) daily. After 4 weeks, serum TG levels in the SPS-treated group were significantly (P<0.05) lower than the baseline (0 week). In conclusion, SPS of soy sauce reduce lipid absorption, and soy sauce is a potentially promising seasoning for the treatment of hyperlipidemia through food, according to "Hypolipidemic effect of Shoyu polysaccharides from soy sauce in animals and humans" by Kobayashi M, Magishi N, Matsushita H, Hashimoto T, Fujimoto M, Suzuki M, Tsuji K, Saito M, Inoue E, Yoshikawa Y, Matsuura T.(3a).
4. Benign prostate hyperplasia (BPH)
In the study to determine the effects of genistein, a major component of soy, on growth of human-patient benign prostatic hypertrophy (BPH) and prostate cancer tissue in three-dimensional collagen gel-supported histoculture, showed that Genistein in doses of 1.25-10 micrograms/ml decreased the growth of BPH tissue in histoculture in a dose-dependent manner, with little additional effect at higher doses. Prostate cancer tissue in histoculture was similarly inhibited by these doses of genistein(4).
5. Cough
Im the study to analyze the relation between dietary intake at baseline and new onset of cough with phlegm in a population-based cohort of 63,257 middle-aged Chinese men and women initiated in Singapore between 1993 and 1998, found that a diet high in fiber from fruit and, possibly, soyfoods may reduce the incidence of chronic respiratory symptoms. Associated nutrients, such as flavonoids, may contribute to this association(5).
6. Endometriosis
In the study to examine the associations among soy isoflavone intake, estrogen receptor 2 (ESR2) gene polymorphisms and risk of endometriosis, showed that Higher levels of urinary genistein and daidzein were associated with decreased risk of advanced endometriosis (P for trend = 0.01 and 0.06, respectively) but not early endometriosis. For advanced endometriosis, the adjusted odds ratio for the highest quartile group was 0.21 (95% confidence interval = 0.06-0.76) for genistein and 0.29 (0.08-1.03) for daidzein, when compared with the lowest group. Inverse associations were also noted between urinary isoflavones and the severity of endometriosis (P for trend = 0.01 for genistein and 0.07 for daidzein). For advanced endometriosis, ESR2 gene RsaI polymorphism appeared to modify the effects of genistein (P for interaction = 0.03)(6).
7. Fibroids
Genistein is a soy-derived phytoestrogen. In the study to investigated the significant inhibitory effect of genistein on estradiol (E(2))-induced leiomyoma cells proliferation, indicated that PPARgamma was expressed in ELT-3 cells and genistein acted as PPARgamma ligand. This inhibitory effect of genistein was attenuated by the treatment of cells with PPARgamma antagonist bisphenol A diglycidyl ether (BADGE) or GW9662 and suggested that the repressive effect of genistein on E(2)-induced ELT-3 cell proliferation is through the activation of PPARgamma. Genistein may be useful as an alternative therapy for leiomyoma(7).
8. Fibromyalgia
Some researchers suggested that Shakes that contain soy and shakes that contain casein, when combined with a multidisciplinary fibromyalgia treatment program, provide a decrease in fibromyalgia symptoms. Separation between the effects of soy and casein (control) shakes did not favor the intervention. Therefore, large-sample studies using soy for patients with fibromyalgia are probably not indicated(8).
9. Graves' disease
In the study to investigate the effect of quercetin in primary cultured orbital fibroblasts from GO, targeting pathways of inflammation, aberrant accumulation of extracellular matrix macromolecules, and adipose tissue expansion. showed that Treatment with noncytotoxic doses of quercetin inhibited accumulation of intracytoplasmic lipid droplets and resulted in a dose-dependent decrease in expression of peroxisome proliferator-activated receptor γ, CCAAT/enhancer-binding protein (C/EBP) α, and C/EBPβ proteins. In conclusion, inhibition of inflammation, hyaluronan production, and adipogenesis by the natural plant product quercetin in vitro provides the basis for further study of its potential use in the treatment of GO(9).
10. Hepatitis
Quercetin, a ubiquitous plant flavonoid, has been identified to inhibit NS3 activity in a specific dose-dependent manner in an in vitro catalysis assay, showed that quercetin has a direct inhibitory effect on the HCV NS3 protease. These results point to the potential of quercetin as a natural nontoxic anti-HCV agent reducing viral production by inhibiting both NS3 and heat shock proteins essential for HCV replication(10).
11. Choltesterol
In the study to investigate the anti-hyperlipidemic effect of soy bean extract solution fermented by Bacillus subtilis MORI (BTD-1E) in obese db/db mice, showed that Eight-week-old male db/db mice were administered 33.3 mg/kg BTD-1E solution orally once a day for four weeks. The BTD-1E group showed significantly lower body weight compared with the db control group (P<0.05). The BTD-1E group showed significantly lower serum total cholesterol and LDL cholesterol levels compared with the db control group, respectively (P<0.05, P<0.01). The BTD-1E group showed significantly decreased liver weight relative to final body weight compared with the db control group (P<0.01). After four weeks of BTD-1E administration, lipid droplets in the liver were apparently decreased in the BTD-1E group compared to the db control group. In summary, our results suggest that BTD-1E has an anti-hyperlipidemic effect in the obese mouse model(11).
12. HPV (human papilloma virus)
According to the study of the potential immunomodulatory effects of genistein on the immune system and against TC-1 tumor cell line were evaluated in adult female C57BL/6 mice, Dr. Ghaemi A, and the research team at the Golestan University of Medical Sciences indicated that the effect of GEN on tumor growth may be attributed to its effect on lymphocyte proliferation, cytolytic activity and IFN-γ production. GEN exerts an immunomodulatory effect in a mouse model of Human Papillomavirus (HPV) associated-cervical cancer(12).
13. Hypertension
in the study to evaluate the antihypertensive potential of soy milk (500 mL twice daily) compared with cow's milk was investigated in a 3-mo double-blind randomized study of 40 men and women with mild-to-moderate hypertension, found that , chronic soy milk consumption had modest, but significant hypotensive action in essential hypertensive subjects. This hypotensive action was correlated with the urinary excretion of the isoflavonoid genistein(13).
14. Irritable bowel syndrome
In the study to evaluate (i) the effects of a phytoestrogen-rich soy germ fermented ingredient (SG) on visceral hypersensitivity, hyperpermeability and other symptoms in stressed intact female rats, (ii) the mechanisms of action involved on the basis of both estrogenic and protease inhibitor activities of SG, researchers showed that A 2-wk oral treatment with SG prevented the stress-induced hyperpermeability and visceral hypersensitivity in cyclic rats through ER activation, and blocked the increase in colonic proteolytic activity, suggesting that SG can be promising in IBS management(14).
15. Lactose intolerance
Modern soy formulas meet all nutritional requirements and safety standards of the Infant Formula Act of 1980. They are commonly used in infants with immunoglobulin E-mediated cow's milk allergy (at least 86% effective), lactose intolerance, galactosemia, and as a vegetarian human milk substitute. Largely as a result of research in animal models, concerns have been voiced regarding isoflavones in soy infant formulas in relation to nutritional adequacy, sexual development, neurobehavioral development, immune function, and thyroid disease, according to the study of Safety of soy-based infant formulas containing isoflavones: the clinical evidence(15).
16. Liver disease
In the stdu8y to evaluate the protective role of soy against CCl(4)-induced liver damage in rats as four experimental groups were treated for 8 weeks and included the control group,showed that Supplementation with soy succeeded to restore the elevation of liver enzymes activities and improved serum biochemical parameters. Moreover, soy supplementation improved the antioxidant enzymes, decreased lipid peroxidation, and improved the histological picture of the liver tissue. It could be concluded that soy-protein-enriched isoflavones may be a promising agent against liver diseases(16).
17. Multiple sclerosis
In the study to investigate the use of genistein for the treatment of the murine model of MS showed that genistein treatment ameliorated significantly the clinical symptoms, modulating pro- and anti-inflammatory cytokines. Moreover, we analyzed the leukocyte rolling and adherence in the CNS by performing intravital microscopy. Genistein treatment resulted in decreased rolling and adhering of leukocytes as compared to the untreated group(17).
18. Obesity
In the study of Role of dietary soy protein in obesity, researchers at the George Washington University Medical Center, indicated that there were an increasing body of literature suggests that soy protein and its isoflavones may have a beneficial role in obesity. Several nutritional intervention studies in animals and humans indicate that consumption of soy protein reduces body weight and fat mass in addition to lowering plasma cholesterol and triglycerides. In animal models of obesity, soy protein ingestion limits or reduces body fat accumulation and improves insulin resistance, the hallmark of human obesity. In obese humans, dietary soy protein also reduces body weight and body fat mass in addition to reducing plasma lipids(18).
19. Osteoporosis
In the study to clarify the effect of ingesting soy isoflavone extracts (not soy protein or foods containing isoflavones) on bone mineral density (BMD) in menopausal women, found that the varying effects of isoflavones on spine BMD across trials might be associated with study characteristics of intervention duration (6 vs. 12 months), region of participant (Asian vs. Western), and basal BMD (normal bone mass vs. osteopenia or osteoporosis). No significant effects on femoral neck, hip total, and trochanter BMD were found. Soy isoflavone extract supplements increased lumbar spine BMD in menopausal women(19).
20. Parkinson's disease
In the study of the protective effect of the bioflavonoid quercetin on behaviors, antioxidases, and neurotransmitters in 1-methyl-4-phenyl-1, 2, 3, 6-tetrahydropyridine-(MPTP-) induced Parkinson's disease (PD, show that quercetin treatment markedly improves the motor balance and coordination of MPTP-treated mice. Significant increases were observed in the activities of glutathione peroxidase (GPx), superoxide dismutase (SOD), and Na(+), K(+)-ATPase, AchE, the content of dopamine (DA) in the quercetin plus MPTP groups compared to those in the MPTP group. Significant reduction the 4-hydroxy-2-nonenal (4-HNE) immunoreactivity in striatum of brains was observed in the quercetin plus MPTP groups in comparison to the MPTP group. Taken together, we propose that quercetin has shown antiparkinsonian properties in our studies. More work is needed to explore detailed mechanisms of action(20)
21. Pelvic inflammatory disease
In the study of Changes in the anti-inflammatory activity of soy isoflavonoidgenistein versus genistein incorporated in two types of cyclodextrin derivatives, found that genistein is an active anti-inflammatory phytocompound andits complexation with hydrophilic beta-cyclodextrin derivatives leads to a stronger antiinflammatoryactivity(21).
22. Premenstrual syndrome
In the study to identify the potential relationship between soy isoflavones and premenstrual syndrome, showed that after two cycles of ISP containing IF intervention, total symptoms (F(2,36) 8.20, P=0.000) and physical symptoms (F(2,36) 8.18, P=0.000) were significantly reduced compared with baseline after both active and placebo treatments, although differences between active and placebo treatment were non-significant. Specific premenstrual symptoms, headache (F(2,32) 4.10, P=0.026) and breast tenderness (F(2,32) 4.59, P=0.018), were reduced from baseline after soy IF, but not milk protein placebo. Cramps (F(2,32) 4.15, P=0.025) and swelling (F(2,32) 4.64, P=0.017) were significantly lower after active treatment compared with placebo. Concentrations of genistein and daidzein were increased following soy IF consumption, but equol production did not enhance symptom reduction(22).
23. Thyroid disorders
In the study to evaluate the relevant literature and provide the clinician guidance for advising their patients about the effects of soy on thyroid function, showed that soy foods, by inhibiting absorption, may increase the dose of thyroid hormone required by hypothyroid patients. However, hypothyroid adults need not avoid soy foods. In addition, there remains a theoretical concern based on in vitro and animal data that in individuals with compromised thyroid function and/or whose iodine intake is marginal soy foods may increase risk of developing clinical hypothyroidism(23). Others suggested that Seaweed ingestion increased I/C concentrations (P < .0001) and serum TSH (P < .0001) (1.69 +/- 0.22 vs. 2.19 +/- 0.22 microU/mL, mean +/- SE). Soy supplementation did not affect thyroid end points. Seven weeks of 5 g/day seaweed supplementation was associated with a small but statistically significant increase in TSH. Soy protein isolate supplementation was not associated with changes in serum thyroid hormone concentrations(23a).
24. Etc.
F. Quoted Frpm Foods to prevent and treat cancers
1. Bladder cancer
Soy phytochemicals have been associated with the protective effect against bladder cancer as it contains genistein, and the isoflavone-rich soy phytochemical concentrate (SPC). Dr. Singh AV and the research team at the Beth Israel Deaconess Medical Center, showed that Mice treated with genistin and SPC had reduced final tumor weights by 56% (P < 0.05) and 52% (P < 0.05), respectively, associated with induction of tumor cell apoptosis and inhibition of tumor angiogenesis in vivo. In addition, SPC treatment, but not genistin treatment, significantly inhibited lung metastases by 95% (P < 0.01) associated with significant down-regulation of NF-kappaB expression in tumor tissues and reduction of circulating insulin-like growth factor-I levels, suggesting that SPC may contain other bioactive ingredients that have antimetastatic activity(1).
2. Cervical cancer
Epidemiological and preclinical evidence suggests that polyphenolic phytochemicals exemplified by epigallocatechin gallate from tea, curcumin from curry and soya isoflavones possess cancer chemopreventive properties. Dr. Thomasset SC and scientists at the University of Leicester, in the review of above showed that the available evidence for tea polyphenols tentatively supports their advancement into phase III clinical intervention trials aimed at the prevention of progression of prostate intraepithelial neoplasia, leukoplakia or premalignant cervical disease. In the case of curcumin and soya isoflavones more studies in premalignacies seem appropriate to optimise the nature and design of suitable phase III trials. The abundance of flavonoids and related polyphenols in the plant kingdom makes it possible that several hitherto uncharacterised agents with chemopreventive efficacy are still to be identified, which may constitute attractive alternatives to currently used chemopreventive drugs(2).
3. Breast cancer
In a study of " Biological effects of a diet of soy protein rich in isoflavones on the menstrual cycle of premenopausal women" , by A Cassidy, S Bingham and KD Setchell (Source from Dunn Clinical Nutrition Centre, Cambridge, UK. ) posted in The Americal Journal Clinical Nutrition, researchers indicated that these effects are presumed to be due to nonsteroidal estrogens of the isoflavone class, which behave as partial estrogen agonists/antagonists. The responses to soy protein are potentially beneficial with respect to risk factors for breast cancer and may in part explain the low incidence of breast cancer and its correlation with a high soy intake in Japanese and Chinese women(4). Other suggested high dietary levels of soy isoflavones do not stimulate breast or uterine proliferation in postmenopausal monkeys and may contribute to an estrogen profile associated with reduced breast cancer risk(6). One study indicated that Soy isoflavone genistein induces cell death in breast cancer cells through mobilization of endogenous copper ions and generation of reactive oxygen species(3)
4. Endomatrial Cancer
In the study to investigate the interactive effect of polymorphisms in the sex hormone-binding globulin (SHBG) gene with soy isoflavones, tea consumption, and dietary fiber on endometrial cancer risk in a population-based, case-control study of 1,199 endometrial cancer patients and 1,212 controls, found that the Asp(327)Asn (rs6259) polymorphism was associated with decreased risk of endometrial cancer, particularly among postmenopausal women (OR = 0.79, 95% CI = 0.62-1.00). This single nucleotide polymorphism (SNP) modified associations of soy isoflavones and tea consumption but not fiber intake with endometrial cancer, with the inverse association of soy intake and tea consumption being more evident for those with the Asp/Asp genotype of the SHBG gene at Asp(327)Asn (rs6259), particularly premenopausal women (P(interaction) = 0.06 and 0.02, respectively, for soy isoflavones and tea intake)(4). Other researchers suggested that a reduced risk of endometrial cancer was associated with total isoflavone intake (highest vs lowest quintile, ≥7.82 vs <1.59 mg per 1000 kcal/d, RR = 0.66, 95% CI = 0.47 to 0.91), daidzein intake (highest vs lowest quintile, ≥3.54 vs <0.70 mg per 1000 kcal/d, RR = 0.64, 95% CI = 0.46 to 0.90), and genistein intake (highest vs lowest quintile, ≥3.40 vs <0.69 mg per 1000 kcal/d, RR = 0.66, 95% CI = 0.47 to 0.91). No statistically significant association with endometrial cancer risk was observed for increasing intake of legumes, soy, tofu, or glycitein. Truncated age-adjusted incidence rates of endometrial cancer for the highest vs lowest quintile of total isoflavone intake were 55 vs 107 per 100 000 women per year, respectively. The partial population attributable risk percent for total isoflavone intake lower than the highest quintile was 26.7% (95% CI = 5.3% to 45.8%)(4a).
5. Thyroid cancer
In the study to observe that an acidic methanolic extract of soybeans contains compounds that inhibit thyroid peroxidase-(TPO) catalyzed reactions essential to thyroid hormone synthesis, showed that In the presence of iodide ion, genistein and daidzein blocked TPO-catalyzed tyrosine iodination by acting as alternate substrates, yielding mono-, di-, and triiodoisoflavones. Genistein also inhibited thyroxine synthesis using iodinated casein or human goiter thyroglobulin as substrates for the coupling reaction(5).
6. Stomach Cancer/Gastric Cancer
Genistein is a phytochemical in the Isoflavones, belonging to the group of Flavonoids (polyphenols), found abundantly in food of the family of legumes, soy, etc. In the study to determinewhether the effect of genistein is mediated via suppression of cyclo-oxygenase (COX)-2 protein, and elucidated the mechanism of action of this effect in the human gastric cancer cell line BGC-823, showed that Genistein treatment inhibited cell proliferation and induced apoptosis in a dose- and time-dependent manner; Western blotting analysis indicated a significant dose-dependent decrease in COX-2 protein levels. Genistein treatment exerted a significant inhibitory effect on activation of the transcription factor nuclear factor κB (NF-κB). Additionally, the NF-κB inhibitor pyrrolidine dithiocarbamate caused a reduction in COX-2 protein levels and NF-κB activation, similar to the effect of genistein(6).
7. Melanoma skin cancer
Gallic acid (GA) is a phytochemical in the class of Phenolic acids, found abundantly in tea, mango, strawberries, soy, etc. In the study to examine the influence of GA on the protein levels and gene expression of MMP-2 and MMP-9 and in-vitro migration and invasiveness of human melanoma cells, showed that GA has antimetastatic potential by decreasing invasiveness of cancer cells. Moreover, this action of GA was involved in the Ras, p-ERK signaling pathways resulting in inhibition of MMP-2 in A375.S2 human melanoma cells. These data, therefore, provide evidence for the role of GA as a potential cancer chemotherapeutic agent, which can markedly inhibit the invasive capacity of melanoma cells(7).
