Relative mRNA expression of maternal genes (Bmp15, Gdf9, cyclin B1, and c-mos) (A)
and poly(A) tail length (B) in FCCP- or ddC-treated MII oocytes. Porcine
Gapdh mRNA expression was used as an internal control, and the
control group was set at 1. Ctrl, control; F, FCCP; D, ddC. Lane 1, control; lanes 2
and 3, oocytes treated with 200 or 2000 nM FCCP, respectively; lanes 4 and 5,
oocytes treated with 200 or 2000 µM ddC, respectively. Arrows point to the initial
length of the poly(A) tail. Values represent means ± SEM from three separate
experiments. *P < 0.05, compared with the control.
