Figure 2. Relative MPF and MAPK activities (A to D) and RhoA-GTP levels (E) in oocytes after different treatments.
In figures A to D, black and gray bars represent MPF and MAPK activities, respectively. MII: Freshly matured oocytes; D and D-: Oocytes with and without protrusion respectively after demecolcine; AD-: Aged oocytes without protrusion after demecolcine; +: In the presence of; R: ROS; U: U0126; Y: Y27632; OA.5h and OA4h: OA for 0.5 and 4 h respectively; MD2: MAD2. a–d: Values without a common letter above their bars differ (P<0.05) within enzyme activities.
