Figure 1. Ethanol activation rates after mouse oocytes collected 13 h post hCG were aged for 9 h in CZB, FCM or FCM containing 5-μM MG132 (MG) (Panel A) or different concentrations of PLC inhibitor U73122 (Panel B) or cytochrome c inhibitor B-IP3RCYT (Panel C). Each treatment was repeated 4 times with each replicate containing about 30 oocytes. a-c: Values without a common letter above their bars differ significantly (P < 0.05).
