The histone methyltransferase G9a (euchromatic histone lysine methyltransferase 2, EHMT2), which mostly mediates mono- and dimethylation by histone H3 lysine 9 (H3K9), influences gene expression involved in embryonic improvement and tissue differentiation. Overexpression of G9a has been observed in a number of cancer kinds, and diverse classes of G9a inhibitors have already been developed as possible anticancer agents. Here, we critique the emerging evidence suggesting the involvement of alterations in G9a activity in brain tumors, namely glioblastoma (GBM), the principle sort of primary malignant brain cancer in adults, and medulloblastoma (MB), probably the most common kind of malignant brain cancer in youngsters. We also discuss the function of G9a in neuroblastoma (NB) and also the drug improvement of G9a inhibitors. Search phrases: G9a; EHMT2; glioblastoma; medulloblastoma; epigenetics; brain tumor1. Introduction The concept of epigenetic regulation comprises heritable and non-heritable long-term modifications in gene expression that happen to be not dependent on mutations in DNA sequences. Epigenetic mechanisms that regulate gene expression, for instance post-translational mo.
