Abstract:ADP-ribosylation factor 6 (ARF6), a GTPase associated with cancer metastasis, is activated in the lung endothelium in pulmonary arterial hypertension (PAH). To identify ARF6-regulated pathways relevant to PAH, we performed a state-of-the-art proteomic analysis of human pulmonary artery endothelial cells (HPAECs) overexpressing the wildtype, constitutively active, fast-cycling and dominant negative mutants of ARF6. The analysis revealed a novel link of ARF6 with hypoxia-inducible factor (HIF), in addition to en… Show more
