Exp Eye Res:Sirt3调节线粒体自噬水平以促进糖尿病角膜上皮伤口愈合

福建医科大学附属医院眼科的Hu J等人近日在Exp Eye Res杂志上发表了一篇文章,他们研究的目的是研究Sirt3(沉默交配型信息调节2同源3)如何通过调节线粒体自噬促进糖尿病角膜上皮伤口的愈合。

福建医科大学附属医院眼科的Hu J等人近日在Exp Eye Res杂志上发表了一篇文章,他们研究的目的是研究Sirt3(沉默交配型信息调节2同源3)如何通过调节线粒体自噬促进糖尿病角膜上皮伤口的愈合。

他们在TKE2细胞(小鼠角膜缘/角膜上皮衍生的祖细胞系)和角膜上皮细胞中进行研究,主要研究HG(高葡萄糖,25mM D-葡萄糖)对代表线粒体自噬的Sirt3和LC3B(轻链3β)的影响。使用RT-PCR和Western印迹分析C57BL / 6J-Ins2Akita(Ins2Akita / +)小鼠样品。用细胞迁移实验、免疫荧光、免疫荧光共定位和角膜损伤模型研究Sirt3过度表达的情况下如何促进糖尿病角膜上皮创伤愈合。

他们发现HG在TKE2细胞和来自Ins2Akita / +小鼠的角膜中均降低了Sirt3的表达,同时也降低了线粒体自噬。Sirt3的过表达通过上调线粒体自噬水平,促进了HG条件下的伤口愈合速度。当Foxo3a(Forkhead box O3)/ PINK1(PTEN诱导的假定激酶蛋白1)-Parkin途径被Sirt3过表达激活时,线粒体自噬水平显着增加,这表明线粒体自噬在HG条件下参与细胞损伤。

因此,作者认为,本研究证实了Sirt3调节线粒体自噬在体内和体外促进糖尿病角膜上皮创伤愈合的机制,这表明Sirt3可能对糖尿病性角膜病变(DK)产生积极影响。

Hypertension:通过SIRT3抑制内皮-间充质转换可延缓高血压肾损伤进展

内皮-间充质细胞转换(EndoMT)是促进慢性肾病纤维化的潜在重要因素。但是,我们对其在高血压肾损伤中的作用和分子基础知之甚少。现Jing-rong Lin等人对去乙酰化酶(SIRT)3对高血压肾损伤中的EndoMT的作用及其潜在机制进行探究。经研究发现SIRT3的表达在AngII(血管紧张素II)诱导的高血压模型中显着降低,并伴有EndoMT诱导、活性氧产生增多和肾纤维化。给SIRT3敲除(SI

Cell:揭示SIRT3在调节线粒体健康中的关键作用

就蛋白而言,去乙酰化酶(sirtuin)是令人喜欢的,而且因它们与衰老和年龄相关疾病相关联而受到人们的广泛关注。作为去乙酰化酶的来源,线粒体,也因在健康和疾病中的作用而闻名于世。 来自美国哈佛医学院的Marcia Haigis和她的团队从事基础研究,提出了一个较为深刻的问题:在细胞中,哪些蛋白与去乙酰化酶进行交谈? 为了解决这个问题,在一项新的研究中,Haigis团队构建出在线粒体中发现的去乙

Diabetes:SIRT3可以阻止高脂饮食诱导的胰岛素抵抗

研究发现蛋白的高度乙酰化与葡萄糖耐量受损和胰岛素抵抗相关,这提示调节乙酰化过程的酶在肥胖和2型糖尿病的病理生理中起非常重要的作用。

Circulation:MicroRNA-195通过调节去乙酰化酶3的表达和线粒体蛋白乙酰化水平调节衰竭心肌细胞的能量代谢

心力衰竭导致衰竭心肌线粒体功能障碍和代谢异常,并伴有心室重塑。线粒体去乙酰化酶3(SIRT3)通过调节线粒体乙酰基在维持线粒体功能中发挥重要作用。目前已发现某些microRNAs可通过调节心肌的关键信号因子在心室重塑过程中发挥重要作用。现有研究人员对microRNA-195(miR-195)和SIRT3调控心室重塑的机制,及其之间是否存在相互关系进行研究。研究人员通过人类心肌样AC16细胞分析细胞
