Fig. 4: Cleavage levels of apoptosis-related proteins in Casp9+/+, Casp9+/−, and Casp9−/− ovaries at 16.5 and 18.5 dpc.

A Immunoblot of CASP9, CASP3, PARP, and β-actin as a loading control. B The ratio of cleaved form to full form of CASP3. C The ratio of cleaved form to full form of PARP1. Data are shown as mean ± SEM (n ≧ 3). **P < 0.01, statistical significance by t-test
