1 The Folate Cycle Enzyme MTHFR is a Critical Regulator of Cell Response to MYC-Targeting Therapies. Folic Acid MYC proto-oncogene, bHLH transcription factor Homo sapiens
2 Here, we identify amino acid-related pathways connected to the folate cycle whose activation predicts sensitivity to MYC-targeting therapies in acute myeloid leukemia (AML). Folic Acid MYC proto-oncogene, bHLH transcription factor Homo sapiens
3 We establish that folate restriction and deficiency of the rate-limiting folate cycle enzyme, MTHFR - which exhibits reduced-function polymorphisms in about 10% of Caucasians - induce resistance to MYC targeting by BET and CDK7 inhibitors in cell lines, primary patient samples, and syngeneic mouse models of AML. Folic Acid MYC proto-oncogene, bHLH transcription factor Homo sapiens
4 We establish that folate restriction and deficiency of the rate-limiting folate cycle enzyme, MTHFR - which exhibits reduced-function polymorphisms in about 10% of Caucasians - induce resistance to MYC targeting by BET and CDK7 inhibitors in cell lines, primary patient samples, and syngeneic mouse models of AML. Folic Acid MYC proto-oncogene, bHLH transcription factor Homo sapiens
5 Our data provide a rationale for screening MTHFR polymorphisms and the folate cycle status to nominate patients most likely to benefit from MYC-targeting therapies. Folic Acid MYC proto-oncogene, bHLH transcription factor Homo sapiens
