Figure 1. Quantitative reverse transcription PCR (qRT-PCR) analysis of relative Sf-1/β-actin mRNA levels in testicular tissue, used as a normalizer, and in rat adrenal glomerulosa (G) and fasciculata/reticularis (F/R) primary cells. Data are reported as the means±SD from three experiments. Statistical significance was assessed by paired t-tests and one-way ANOVA.
