Abstract

The calgranulin-like protein MTS1/S100A4 and the receptor for advanced glycation end-products (RAGE) have recently been implicated in mediating pulmonary arterial smooth muscle cell proliferation and vascular remodelling in experimental pulmonary arterial hypertension (PH). Here, the effects of RAGE antagonism upon 2 weeks of hypobaric hypoxia (10% O2)-induced PH in mice were assessed. Treatment with sRAGE was protective against hypobaric hypoxia-induced increases in right ventricular pressure but distal pulmonary vascular remodelling was unaffected. Intralobar pulmonary arteries from hypobaric hypoxic mice treated with sRAGE showed protection against a hypoxia-induced reduction in complianc..
