Identification of ras and ras-related low-molecular-mass GTP-binding proteins associated with rat lung lamellar bodies.

abstract：:Although hemolytic anemia-associated pulmonary hypertension (PH) and pulmonary arterial hypertension (PAH) are more common than the prevalence of idiopathic PAH alone, the role of hemolysis in the development of PAH is poorly characterized. We hypothesized that hemolysis independently contributes to PAH pathogenesis v...
