- W2020362954 abstract "In the ovary, mammalian oocytes resume meiosis and mature to the second metaphase when they are stimulated with gonadotrophins. Similarly, oocytes can mature in vitro when they are liberated from ovarian follicles and cultured under appropriate conditions. Early in the process of maturation, oocytes undergo dramatic but well‐ordered changes at the G2/M transition in the cell cycle including: (i) chromosome condensation; (ii) nucleolus disassembly; (iii) germinal vesicle breakdown (GVBD); and (iv) spindle formation in the first metaphase (MI‐spindle). These events have been thought to be induced by MPF (maturation‐promoting factor or M‐phase promoting factor), now known as Cdc2 kinase or Cdk1 kinase, which consists of a catalytic subunit, Cdc2, and a cyclin B regulatory subunit. In fact, nuclear lamins are phosphorylated by Cdc2 kinase, and nuclear membrane breakdown occurs concomitantly with the activation of Cdc2 kinase in the M‐phase of both somatic cells and oocytes. Based on the classical and recent studies of the pig oocyte, however, the chromosomes start to condense and the nucleolus disassembles before full activation of Cdc2 kinase, and the MI‐spindle is formed after activation of both Cdc2 kinase and MAP kinase; another kinase known to become activated during oocyte maturation. These findings suggest that chromosome condensation and nucleolus disassembly in oocytes are induced by either some kinase(s) other than Cdc2 kinase and MAP kinase or some phosphatase(s). The accumulation of new results regarding the molecular nature of oocyte maturation is important for improving the reproductive technologies in domestic animals as well as in humans.
