Comment EHMT2 (G9a) is an epigentitc 'writer' that catalyses mono- and di-methylation of histone H3 at lysine residues 9 (H3K9me1, H3K9me2) and 27 (H3K27me1 and H3K27me2), and plays an important role in regulation of gene expression.
Pharmacological inhibition of EHMT2 re-activates production of fetal haemoglobin in adult erythrocytes in vitro [15,28]. This effect is predicted to offer disease-modifying benefit for patients with β-globinopathies such as sickle cell disease and β-thalassemia. A first-in-class EHMT2 inhibitor, EZM8266, was investigated as a novel therapeutic for sickle cell disease. EHMT2 is also an oncology drug target. In ER+ve breast cancers treated with adjuvant endocrine therapies epigenetic reprogramming can induce dormancy and persistent micrometastatic deposits of tumour cells that can cause relapses years after treament. Inhibiting EHMT2 impeded the formation of dormant cells in estrogen pretreated MCF7 cells, suggesting this as a mechanism to combat therapy-induced dormancy in ER+ve endocrine therapy-adapted breast cancer [29].
