Epigenetic modification of histone 3 at lysine 9 in sheep zygotes and its relationship with DNA methylation
29 May 2008
Abstract excerpt
BACKGROUND: Previous studies indicated that, unlike mouse zygotes, sheep zygotes lacked the paternal DNA demethylation event. Another epigenetic mark, histone modification, especially at lysine 9 of histone 3 (H3K9), has been suggested to be mechanically linked to DNA methylation. In mouse zygotes, the absence of methylated H3K9 from the paternal pronucleus has been thought to attribute to the paternal DNA...
