Hypoxia-Induced miR-210 Is Necessary for Vascular Regeneration upon Acute Limb Ischemia.

ABSTRACT: Critical limb ischemia is the most serious form of peripheral artery disease, characterized by severe functional consequences, difficult clinical management and reduced life expectancy. The goal of this study was to investigate the miR-210 role in the neo-angiogenic response after acute limb ischemia. Complementary approaches were used in a mouse model of hindlimb ischemia: miR-210 loss-of-function was obtained by administration of LNA-oligonucleotides anti-miR-210; for miR-210 gain-of-function, a doxycycline-inducible miR-210 transgenic mouse was used. We tested miR-210 ability to stimulate vascular regeneration following ischemia. We found that miR-210 was necessary and sufficient to stimulate blood perfusion recovery, as well as arteriolar and capillary density increase, in the ischemic
