Additional experiment showed that lactational fenvalerate exposure markedly reduced mRNA and protein levels of testicular P450scc, a testosterone (T) synthesis enzyme.

And then the morphous was assessed by conventional light microscopy, steroid hormones were measured by RIA, and the expressions of steroidogenic acute regulatory protein (StAR) and cytochrome P450 side-chain cleavage enzyme (P450scc) were monitored by real-time quantitative PCR analysis.

Expression of P450 side chain cleavage enzyme (P450scc) and steroidogenic acute regulatory protein (StAR) were monitored by real-time PCR and Western blotting.

In addition, fenvalerate decreased steroidogenic acute regulatory protein (StAR) mRNA and protein levels, and also profoundly inhibited the activity of P450 side chain cleavage enzyme (P450scc) which was consistent with the decreased expression of P450scc mRNA and protein in MLTC-1 cells.
