BETs Need Greens: Folate Deficiency and Resistance to MYC-Targeted Therapies
Abstract
Recently, small-molecule inhibitors of general transcriptional regulators such as BET proteins and the RNA-PolII-regulating kinase CDK7 have been shown to have efficacy in multiple solid and liquid tumors. An article in this issue of Cancer Discovery identifies a nongenetic mechanism of resistance related to deficiency of folate that leads, via increased S-adenosylhomocysteine and reduced repressive histone methylation, to reactivation of a transcriptional program which promotes AML cell survival under the pressure of BET inhibition.See related article by Su et al., p. 1894.
