GSE146502 DNA methylation changes induced by hypomethylating agent, Azacitidine (AZA); IDH1 inhibitor, BAY1436032 (BAY) and sequential and simultaneous combination of BAY and AZA in in vitro treated human (CD45+) cells isolated from the bone marrow of IDH1mut

Mutated IDH1/2 produces the metabolite 2-hydroxyglutarate (2HG), which interferes with epigenetic regulation of gene expression, and thus may promote tumorigenesis. Data for IDH1 inhibitors show that 30-40% of AML patients respond to monotherapy with a median duration of response of 8 months, suggesting that IDH1 inhibitors should be combined with other agents to improve efficacy. BAY 1436032 (BAY) is an oral pan-mutant IDH1 inhibitor currently undergoing phase 1 clinical trials. 5-Azacitidine (AZA) is a hypomethylating agent and can activate key epigenetically silenced pathways in AML cells, leading to an arrest of AML cell proliferation.
