Cobalt ions significantly increase global histone H3K4me3, H3K9me2, H3K9me3, H3K27me3 and H3K36me3, as well as uH2A and uH2B and decreases acetylation at histone H4 (AcH4) in vivo. Cobalt ions increase H3K9me3 and H3K36me3 by inhibiting histone demethylation process in vivo. And cobalt ions directly inhibit demethylase activity of JMJD2A in vitro. Cobalt ions do not increase the level of uH2A in the in vitro histone ubiquitinating assay and inhibit histone-deubiquitinating enzyme activity in vitro
