Figure 3: CdCl2 induced the expression of progesterone receptor (PR) A and B. The cells were treated with CdCl2 (100, 10 and 1 nM) and progesteron (100 nM). The expression of PRA and PRB in (A) OVCAR3 and (B) SKOV3 cells were assayed using western blotting method. Quantitative analysis of the expression of PRA in (C) OVCAR3, (D) SKOV3 cells; PRB in (E) OVCAR3, (F) in SKOV3 cells were performed by image j software. Asterisks show significant differences compared to Cd(0), (*P < 0.05, **P < 0.01, and ***P < 0.001). P, Progesterone; CC, CdCl2.
