abstractText | We have demonstrated that adiponectin has anti-atherosclerotic properties. We also reported hypoadiponectinemia and nocturnal reduction in circulating adiponectin concentrations in patients of severe obstructive sleep apnea-hypopnea syndrome (OSAS). OSAS is often complicated with pulmonary hypertension. In this study, we investigated the effect of adiponectin on chronic hypoxia-induced pulmonary arterial remodeling in mice. Exposure of mice to 3-weeks sustained hypoxia (10% O(2)) resulted in significant accumulation of adiponectin in pulmonary arteries. The percentage media wall thickness (%MT), representing pulmonary arterial remodeling, under hypoxic condition, was greater in adiponectin-knockout mice than wild-type mice. Overexpression of adiponectin significantly decreased hypoxia-induced pulmonary arterial wall thickening and right ventricular hypertrophy. These findings demonstrate for the first time that overexpression of adiponectin suppresses the development of hypoxic-induced pulmonary remodeling, and that adiponectin may combat a new strategy for pulmonary vascular changes that underlie pulmonary hypertension in OSAS. |
