Figure 4.
The decreased mRNA levels of progesterone synthesis enzymes and PGR expression in the mice of PPOS group
(A–D) Star (A, n = 9–10 mice in each group), Cyp11a (B, n = 9–10 mice in each group), Hsd3B2 (C, n = 10 mice in each group), and Cyp19a (D, n = 7–10 mice in each group) relative mRNA levels in the PPOS and control groups at 4 h after hCG injection.
(E) Immunofluorescence images of PGR expression on the preovulatory follicles in the PPOS and control groups at 6 h after hCG injection (n = 3–5 mice in each group). Scale bar, 50 μm.
(F) The relative PGR fluorescence intensity within control and PPOS groups analyzed by ImageJ software (n = 6 preovulatory follicles within 3–5 mice in each group).
(G) PGR relative mRNA expression levels at 4 h after hCG injection within two groups (n = 7–9 mice in each group).
Statistical analysis was performed by Mann-Whitney test in A–D, F-G. Data are represented as mean ± SEM. ns, no significance (p ≥ 0.05). ∗p < 0.05, ∗∗p < 0.01.
