Figure 7. Effect of lactate on expression of StAR.
(A) A representative western blot analysis for the expression of StAR protein in rat ZG cells after incubation with or without sodium lactate (1–10 mM) in the presence or absence of Ang II (1×10−8 M). (B) Quantification of the effect of lactate on StAR protein expression by standarization against the internal control β-actin. *P<0.05 and ** P<0.01 vs. the corresponding group in the absence of Ang II. #, ##, P<0.05 and P<0.01, respectively by the two way ANOVA.
