Cyclin reporter translation dependence on CPEB1. (A) CPEB binding to Ccnb1, Ccnb2, and Mos mRNAs. After immunoprecipitation of GV oocyte lysate with CPEB1 specific antibody, transcripts recovered in the pellet were reverse-transcribed followed by quantitative PCR with specific primers. The graphs report the mean ± SEM of three independent experiments. (BD) CPEB1 was depleted from the oocytes by injection of morpholino oligomer (MO) or control MO. Either the Ccnb1 or Ccnb2 3′UTR reporter was injected at the same time. After a 24 h incubation, milrinone was removed to induce cell cycle reentry, and the translation of Ccnb1 (C) or Ccnb2 reporter (D) was measured at 6 or 8 h after resumption of meiosis. The graphs are the mean ± SEM of three independent experiments.
