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。

Results Microscopically, different degrees of hepatocytic degenerative changes and hyperplasic fibrous tissue and typical false lobule formation could be seen. Timm's staining result showed uneven distributed black granular deposits in the hepatocytes. No specific PAS staining was observed. Utrastructurally, the mitochondria were increased in volume and dramatically different in shape. The number of lysomes were increased.

结果 光镜下肝细胞表现为不同程度的退行性变，胶原纤维增生以及典型假小叶形成；Timm's染色阳性，发现不均匀分布黑色颗粒或团块样物质沉积；PAS染色则普遍缺乏特异性染色；超微结构显示线粒体形态多样，体积增大，溶酶体增多，粗面内质网管腔扩张，附着核糖体的脱颗粒，以及胞质水肿，质膜溶解。

Our study showed that about 3% mononucleated cells of human peripheral blood could be induced to osteoclast-like cells which have the ability of bone resorption and show TRAP-positive when coculture with UMR106 in the presence of 1,25 dihydroxyvitamin D3, macrophage-colony stimulating factor and dexamethasone.
