Title
The microRNA-328 regulates hypoxic pulmonary hypertension by targeting at insulin growth factor 1 receptor and L-type calcium channel-a1C
Year
2012
Function
"Hypoxia produced a significant inhibition of miRNA-328 expression, which was involved in PA vasoconstriction and remodeling. Overexpressing miRNA-328 in the transgenic mice remarkably decreased the right ventricular systolic pressure and PA wall thickness under both normoxia and hypoxia. MiRNA-328 inhibited L-type calcium channel-a1C expression through a miRNA-328 binding site within the 3' untranslational region of L-type calcium channel-a1C. The L-type calcium channel-a1C inhibition attenuated the PA response to KCl. Furthermore, miRNA-328 suppressed the insulin growth factor 1 receptor, ultimately leading to apoptosis of pulmonary arterial smooth muscle cells."
