Figure 3. E2 decreased sGC α1 mRNA expression in a PI3k-dependent pathway involving non-nuclear ER but does not modify sGC β1 after 3 h of incubation.

Figure 3

Pituitary cells in culture were incubated with vehicle (control) or 1 nM estrogen dendrimer conjugate (EDC), unable to trespass cellular membrane for 3 h with or without 50 µM LY294002 (LY), a PI3K inhibitor, 30 min before treatment. mRNA expression was evaluated by PCR. (A, B) Top, a representative PCRs. Bottom, Corresponding average densitometric values. Bars represent mean ± SE of relative units corresponding to α1 (open bars) and β1 (black bars) mRNA densitometric values normalized to β-actin, as percent of control (n = 3). ANOVA followed by Tukey's test, *P<0.05, **P<0.01 vs. respective controls; #P<0.05, ###P<0.001 vs. EDC.
