title: Effects of p,p'-dichlorodiphenyldichloroethylene on the expressions of transferrin and androgen-binding protein in rat Sertoli cells.
abstract: The mechanisms of reproductive malfunction of male mammals caused by 2,2-bis(4-chlorophenyl)-1,1-dichloroethylene (p,p'-DDE, hereafter DDE) remain unknown. To explore the effects of DDE on the expressions of transferrin (Tf) and androgen-binding protein (ABP), we isolated Sertoli cells from healthy immature rats (18-20 days SD rats), set up Sertoli cell cultures, evaluated the toxicity, and measured the expression levels of mRNA of Tf and ABP genes by the one-step reverse transcriptase polymerase chain reaction method after cultured Sertoli cells were in vitro exposed to DDE at different concentrations for 24 h. The results showed that the number and survival rate of Sertoli cells decreased sharply with increased doses of DDE. The expression level of Tf mRNA decreased, whereas ABP mRNA increased gradually with increased DDE doses. There existed an obvious dose-effect relationship between the concentration of DDE and the expression levels of Tf mRNA and ABP mRNA. These findings suggest that DDE may inhibit the expression of Tf and up-modulate expression of ABP in cultured rat Sertoli cells.
