Oncotarget:不同外泌体在草酸盐肾结石形成中发挥不同的作用

2017-12-03 MedSci MedSci原创

草酸盐(Ox)是一种由肾脏产生的代谢性终产物,与多种病理状态有关。草酸盐在体内的积累是导致草酸钙肾结石的因素之一。为了模拟体内高浓度的Ox环境,我们使用肾小管上皮(HK-2)细胞建立了高Ox的体外模型。评估细胞活力和增殖以评估Ox的不同浓度(0,0.25,0.5,1,2,4,5,8和10mM)对HK-2细胞的作用以选择提取外泌体的最佳浓度和时间。结果显示,使用0,1或2mM Ox处理可改变外泌体的

草酸盐(Ox)是一种由肾脏产生的代谢性终产物,与多种病理状态有关。草酸盐在体内的积累是导致草酸钙肾结石的因素之一。

为了模拟体内高浓度的Ox环境,我们使用肾小管上皮(HK-2)细胞建立了高Ox的体外模型。评估细胞活力和增殖以评估Ox的不同浓度(0,0.25,0.5,1,2,4,5,8和10mM)对HK-2细胞的作用以选择提取外泌体的最佳浓度和时间。

结果显示,使用0,1或2mM Ox处理可改变外泌体的形态和分泌能力。随着Ox浓度的增加,外泌体的峰值和平均粒径减小,但外泌体颗粒浓度、外泌体RNA和外泌体蛋白质的水平增加。不同的胞外囊泡亚型中,外泌体的大小、分布和分泌速率以及RNA和蛋白质含量是不同的。此外,三种亚型的外泌体在微环境中传递不同的信号因子。

因此,我们推测三种亚型的外泌体在细胞间信号传递和CaOx肾结石形成中可能发挥不同的作用。

PNAS:为何你不能代谢掉草酸盐?

多种水果和蔬菜中都含有草酸盐,但人类和大部分动物机体中都缺失代谢草酸盐的能力,即摄入机体中不能破碎草酸盐分子,因此对于某些人而言,机体中草酸盐的积累往往会引发肾结石、关节炎甚至是肾衰竭。 然而有些植物、真菌和细菌却可以破碎草酸盐分子,如今刊登在国际杂志PNAS上的一项研究论文中,来自MIT等处的科学家们通过研究鉴别出了代谢草酸盐过程中的一种特殊的分子机制,这对于后期科学家们开发新型方法来减轻
