FOXA3, a Negative Regulator of Nur77 Expression and Activity in Testicular Steroidogenesis
Figure 6
FOXA3 represses cAMP-induced expression of steroidogenic genes in primary Leydig cells. mRNA expression of steroidogenic genes in primary Leydig cells (A). Mouse primary Leydig cells were transduced with Ad-FOXA3 or Ad-GFP as control. After wash, the cells were further cultured for 48 h that included 4 h of cAMP (200 μM) induction. The gene expression level was normalized to that of GAPDH. Testosterone production was significantly reduced by FOXA3 (B). Cells were transduced in a similar manner and maintained in 200 μM of cAMP for 48 h Culture medium was harvested for RIA assay. The t-test was performed to analyze statistical significance. ; ; .
