Histone 3 lysine 4, 9, and 27 demethylases expression profile in fertilized and cloned bovine and porcine embryos†

Epigenetic modifications in the C-terminal domain of histones coordinate important events during early development including embryo genome activation (EGA) and cell differentiation. In this study, the mRNA expression profile of the main lysine demethylases (KDMs) acting on the lysine 4 (H3K4), 9 (H3K9), and 27 (H3K27) of the histone H3 was determined at pre-, during and post-EGA stages of bovine and porcine embryos produced by in vitro...
