Abstractdc.description.abstractThis search is focused on the study of diet compounds that may have any potential chemopreventive effect against cancer. Some compounds that fulfill this requirement are phytoestrogens. Among them we find genistein (1), the most studied, daidzein (2) and equol (3) (figure 1). To compare the sensitivities of different prostate cancer cells to phytoestrogen treatment, sulphorhodamine B dye assay was performed to determine cell viability. DU-145 and PC-3 prostate cancer cell lines treated with various doses of phytoestrogen (0-12.5-25-50 and 100 mu M) for different times (24, 48 and 72h). For cell invasion or migration assay cells were seeded in a Transwell chamber with or without coating Matrigel respectively. DU-145 and PC-3 cells were treated previously with phytoestrogen (50 mu M) for 24h. The study showed that equol, daidzein and genistein inhibited migration and invasion in prostate cancer cell lines. Moreover, we analyzed the effects of phytoestrogens in MMP-2 and MMP-9 mRNA expression by RT-PCR. The results indicated that equol, daidzein and genistein diminished the expression of MMP-2 and MMP-9 in a cell-dependent manner. Our data suggested that equol, daidzein and genistein inhibited migration and invasion in prostate cancer cell lines. Moreover, the results also suggest that down-regulation of MMP-2 and MMP-9 might be involved in the inhibition of invasion of PC-3 and DU-145 cells after genistein, daidzein and equol treatment.en_US
