Fig. 7. Reduced expression of connexin 37 and connexin 43 in Zp3-Foxo3a Tg mice. Ovaries from 8- and 15- to 17-day-old Tg mice or WT littermates were collected and used for western blot analysis. (A,D) Levels of connexin 37 in WT and Tg ovaries at PD8 and PD15-17; (B,E) levels of connexin 43 in WT and Tg ovaries at PD8 and PD15-17; (C,F) levels of ß-actin, used as a control for protein loading. Experiments were repeated at least three times. For each experiment with PD8 mice, n=10-15; for experiments with PD15-17 mice, n=5-8. Representative images are shown.
