Indeed, the pro-angiogenic microRNA-93 promoted angiogenesis on a mouse model of hind limb ischemia through inhibition of Cyclin-dependent kinase inhibitor 1A, which has been linked with endothelial dysfunction and is implicated in the development of PAD (Kesidou et al., 2020). The gene discussed is CDKN1A; the disease is endothelial dysfunction.
