Project description:TubA is a specific inhibitor of HDAC6, it could regulate oocytes maturation by regulating acetylation of α-tubulin. However, weather it effects maternal mRNA expression remains unkown. Therefore, in this study,we got in vitro maturated MII oocytes in control and 0.1μg/mL treated .Our study suggests that TubA mainly downregulated cell cycle and DNA methylation related genes.
