人类卵母细胞非整倍体发生率的升高需要研究调节适当染色体分离的分子机制。 Aurora 激酶是一个保守的丝氨酸/苏氨酸激酶家族,参与有丝分裂和减数分裂过程中正确的染色体分离。在这里,我们报告了小鼠卵母细胞减数分裂成熟过程中所有三种极光激酶同源物 AURKA、AURKB 和 AURKC 的表达和定位。 AURKA 是表达最丰富的同源物,在减数分裂 I (MI) 和减数分裂 II (MII) 期间定位于纺锤体极,而 AURKB 集中在着丝粒,特别是 MI (Met I) 中期。生殖细胞特异性同源物 AURKC 在两次减数分裂期间沿着染色体的整个长度被发现。在小分子泛极光激酶抑制剂 ZM447439 存在下成熟的卵母细胞会导致 Met I 和 Met II 减数分裂进展和染色体排列缺陷。 AURKB 的过表达(而非 AURKA 或 AURKC)可以挽救染色体排列缺陷,表明 AURKB 是负责调节小鼠卵母细胞减数分裂过程中染色体动态的主要极光激酶。
The elevated incidence of aneuploidy in human oocytes warrants study of the molecular mechanisms regulating proper chromosome segregation. The Aurora kinases are a well-conserved family of serine/threonine kinases that are involved in proper chromosome segregation during mitosis and meiosis. Here we report the expression and localization of all three Aurora kinase homologs, AURKA, AURKB, and AURKC, during meiotic maturation of mouse oocytes. AURKA, the most abundantly expressed homolog, localizes to the spindle poles during meiosis I (MI) and meiosis II (MII), whereas AURKB is concentrated at kinetochores, specifically at metaphase of MI (Met I). The germ cell-specific homolog, AURKC, is found along the entire length of chromosomes during both meiotic divisions. Maturing oocytes in the presence of the small molecule pan-Aurora kinase inhibitor, ZM447439 results in defects in meiotic progression and chromosome alignment at both Met I and Met II. Over-expression of AURKB, but not AURKA or AURKC, rescues the chromosome alignment defect suggesting that AURKB is the primary Aurora kinase responsible for regulating chromosome dynamics during meiosis in mouse oocytes.
