text_1: Removal of H3K9me3 by ectopic expression of other H3K9 demethylases decreases reprogramming efficiency in SCNT experiments.
text_2: Bovine eight-cell SCNT embryos exhibit global hypermethylation of histone H3 lysine 9 tri- and di-methylation (H3K9me3/2), but the intrinsic reason for this remains elusive.
