Effect of vitrification on promoter CpGÂ island methylation patterns and expression levels of DNA methyltransferase 1o, histone acetyltransferase 1, and deacetylase 1 in metaphase II mouse oocytes

Vitrification did not statistically significantly alter the methylation patterns of the promoter CpG islands in Dnmt1o, Hat1, or Hdac1, but did statistically significantly decrease the expression of Dnmt1o mRNA in mouse MII oocytes.
