Cancer cells rely on altered metabolism to support abnormal proliferation. We performed a CRISPR/Cas9 functional genomic screen targeting metabolic enzymes and identified PDXK—an enzyme that produces pyridoxal phosphate (PLP) from vitamin B6—as an acute myeloid leukemia (AML)-selective dependency.. PDXK kinase activity is required for PLP production and AML cell proliferation, and pharmacological blockade of the vitamin B6 pathway at both PDXK and PLP levels recapitulated … Continue reading Vitamin #B6 Addiction in Acute Myeloid #Leukemia
