Temporal Changes in Resting #Heart Rate, Left Ventricular Dysfunction, Heart #Failure and Cardiovascular Disease: CARDIA Study

..Higher alcohol consumption (β=0.03, p<0.001), lower physical activity (β=0.002,p=001), smoking (β=1.58, p<0.001), men (p<0.001), African-Americans (p<0.001), impaired left ventricular relaxation (e´,β=-0.13, p=0.002), and worse diastolic function (E/e´,β=0.1, p=0.01) were associated with longitudinal increases in resting heart rate. We observed 268 cardiovascular disease and 74 heart failure events over a median of 26 years. In Cox models, baseline and temporal changes in resting heart rate were … Continue reading Temporal Changes in Resting #Heart Rate, Left Ventricular Dysfunction, Heart #Failure and Cardiovascular Disease: CARDIA Study

Vitamin #B6 Addiction in Acute Myeloid #Leukemia

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
