Abstract

To determine the effect of soy isoflavones on cell proliferation and the transcription levels of follicle-stimulating hormone receptor (FSHR), inhibin α (INHα), INHβB, androgen binding protein (ABP), transferrin (Tf) and vimentin in testis sertoli cells in SD rats.Sertoli cells were cultured in vitro, exposed to daidzein at 0.03, 0.3, 3, and 30 μmol/L and genistein at 0.05, 0.5, 5 and 50 μmol/L, respectively. MTT was used to detect the proliferation of sertoli cells. Real-time PCR was used to detect the relative mRNA expressions of FSHR, INHα, INHβB, ABP, Tf and vimentin.Compared with control groups, cell proliferation and the relative mRNA expression levels of INHβB and ABP in the treated cells showed no significant alternation. The INHα mRNA expression levels were increased in 0.3 and 3 μmol/L Dai and 0.05 μmol/L Gen, while the mRNA expression levels of FSHR were downregulated in 30 μmol/L Dai and Gen at all concentrations. Tf mRNA expression levels were downregulated in 30 μmol/L Dai and 5 μmol/L and 50 μmol/L Gen, and the mRNA expression levels of vimentin were downregulated in 3 and 30 μmol/L Dai and 50 μmol/L Gen.Soy Isoflavones may have potential detrimental effect on the male reproductive system, as they may impact the function of sertoli cells by downregulating the transcription levels of some important proteins.
