NAMPT and pulmonary arterial hypertension: The downregulation of miR-410 in hypoxia-prompted pulmonary hypertension (HPH) was first exhibited in a hypoxia-interceded HPH mouse model, and afterwards, the transfection of hPAECs with miR-410 imitators or inhibitors was studied to show that miR-410 directs the outflow of NAMPT in hPAECs.
