Objective@#To explore the effects of BPA on the expression of N-cadherin, Vimentin and FSHR in ratSertoli cells.@*Methods@#Primary Sertoli cells collected from prepuberty rats (18-21 d) were cultured for 48 h, and then they were treated with 0, 30, 50, 70 μmol/L BPA respectively for 24 h. The methods of MTT, real-time quantitative PCR and Western blotting were utilized to measure the cellability of Sertoli cells, the mRNA and protein expression levels of N-cadherin, Vimentin and FSHR respectively.@*Results@#Compared with control, the cellabilities of Sertoli cells in 50 μmol/L BPA group and 70 μmol/L BPA group increased significantly (P<0.05) . The cellabilities of Sertoli cells decreased with the increases of exposure doses of BPA. Compared with control, the expression of N-cadherinmRNA only increased in 30 μmol/L BPA group (P<0.05) , the expression of VimentinmRNA decreased significantly in all doses group of BPA (P<0.05) , the expression of FSHR mRNA increased in all doses group of BPA (P<0.05) . Compared with the control, the protein levels of N-cadherin increased significantly in 50 μmol/L BPA group (P<0.05) , the protein levels of Vimentin decreased significantly in all doses group of BPA (P<0.05) , the protein levels of FSHR decreased significantly in 50 μmol/L BPA group and 70 μmol/L BPA group (P<0.05) .@*Conclusion@#The mechanism of testicular toxicity from BPA might be the alterations of N-cadherin, Vimentin and FSHR by disturbing normal spermatogenesis.
