In young human umbilical vein endothelial cells, human aortic endothelial cells, and human coronary artery endothelial cells, miR-217 induces a premature senescence-like phenotype and leads to an impairment in angiogenesis via inhibition of SirT1 and modulation of FoxO1 (forkhead box O1) and endothelial nitric oxide synthase acetylation.

在婴儿脐静脉内皮细胞、人类主动脉内皮细胞以及冠状动脉内皮细胞中，miR-217可以诱导这些细胞出现一种早衰样表型，进而通过抑制SirT1的表达、调控Fox01以及内皮细胞一氧化氮合酶的乙酰化来损伤新生血管的形成。
