  • Title: Genistein attenuates low temperature induced pulmonary hypertension in broiler chicks by modulating endothelial function.
    Author: Yang Y, Gao M, Wu Z, Guo Y.
    Journal: Eur J Pharmacol; 2010 Dec 15; 649(1-3):242-8. PubMed ID: 20854807.
    Abstract:
    Pulmonary arterial hypertension is characterized by high pulmonary blood pressure, vascular remodeling and right ventricular hypertrophy. In the present study, we investigated whether genistein would prevent the development of low temperature-induced pulmonary hypertension in broilers. Hemodynamic parameters, vascular remodeling, the expression of endothelial nitric oxide and endothelin-1 content in lung tissue were evaluated. The results demonstrated that genistein significantly reduced pulmonary arterial hypertension and suppressed pulmonary arterial vascular remodeling without affecting broilers' performance. The beneficial effects appeared to be mediated by restoring endothelial function especially endothelial nitric oxide and endothelin-1, two critical vasoactive molecules that associated with the development of hypertension. Genistein supplementation might be a potential therapeutic strategy for the treatment of pulmonary hypertension.
