Induction of ferroptosis by SIRT1 knockdown alleviates cytarabine resistance in acute myeloid leukemia by activating the HMGB1/ACSL4 pathway.

Resistance to cytarabine is a major obstacle to the successful treatment of acute myeloid leukemia (AML). The present study aimed to explore the mechanism by which sirtuin 1 (SIRT1) reverses the cytarabine resistance of leukemia cells. Cell viability was investigated using the EdU proliferation assay.

Relationship between methylenetetrahydrofolate reductase gene polymorphisms and methotrexate drug metabolism and toxicity.

Background: Acute lymphoblastic leukemia (ALL) is the most common malignancy in children, and methotrexate (MTX) is the key drug for ALL. Studies on the relationship between High-Dose methotrexate (HD-MTX) toxicity and methylenetetrahydrofolate reductase (MTHFR) C677T and A1298C genes have drawn different conclusions. This study aimed to investigate the relationship between the polymorphism of C677T and A1298C genes and the toxicity responses of MTX.
