DEX down-regulates protein levels of CYP17A1 and SCARB1. Seminiferous tubules were cultured in the LIM in the presence of DEX alone or with RU38486 or RU38486 alone for 21 days. Panel a: Western blot measured the proteins levels of CYP17A1 and SCARB1. Panel b: Quantitative data of protein levels (n = 3). D10 = DEX 10 nM, D100 = DEX 100 nM, R = RU38486 1 μM. The data are presented as the mean ± SEM. Identical letters showed no significant difference between two groups at P < 0.05
