Lack of Bcr and Abr Promotes Hypoxia-Induced Pulmonary Hypertension in Mice

Abstract

Bcr and Abr play a critical role in down-regulating hypoxia-induced pulmonary hypertension by deactivating Rac1 and, through this, reducing both oxidative stress generated by leukocytes as well as p38 phosphorylation, IL-6 production and proliferation of pulmonary arterial smooth muscle cells.
