NADH cytochrome b5 reductase 3 (CYB5R3) is critical for reductive reactions such as fatty acid elongation, cholesterol biosynthesis, drug metabolism, and methemoglobin reduction. Although the physiological and metabolic importance of CYB5R3 has been established in hepatocytes and erythrocytes, emerging investigations suggest that CYB5R3 is critical for(More)
RATIONALE Pulmonary hypertension is characterized by pulmonary endothelial dysfunction. Previous work showed that systemic artery endothelial cells express hemoglobin α to control nitric oxide diffusion, but the role of this system in the pulmonary circulation has not been evaluated. OBJECTIVES We hypothesize that up-regulation of hemoglobin α in(More)
