| abstractText | Previously, we have shown that Bcl2l10 is highly expressed in metaphase II (MII)-stage oocytes. The objective of this study was to characterize Bcl2l10 expression in ovaries and to examine the function of Bcl2l10 in oocyte maturation using RNA interference. Bcl2l10 transcript expression was ovary and oocyte specific. Bcl2l10 was highly expressed in oocytes and pronuclear-stage embryos; however, its expression decreased at the two-cell stage and dramatically disappeared thereafter. Microinjection of Bcl2l10 double-stranded RNA into the cytoplasm of germinal vesicle oocytes resulted in a marked decrease in Bcl2l10 mRNA and protein and metaphase I (MI) arrest (78.9%). Most MI-arrested oocytes exhibited abnormalities in their spindles and chromosome configurations. Bcl2l10 RNA interference had an obvious effect on the activity of maturation-promoting factor but not on that of mitogen-activated protein kinase. We concluded that the role of Bcl2l10 is strongly associated with oocyte maturation, especially at the MI-MII transition. |
