Sci Rep:输尿管上皮细胞接触草酸钙单水合物后,含铜不锈钢能够减少细胞毒性和晶体粘附

2018-10-09 AlexYang MedSci原创

草酸钙单水合物(COM)是结石的主要组成成分,并能够造成细胞膜损伤。另外,细胞损伤是COM晶体结合造成的主要事件。最近,有研究人员在含铜不锈钢(316L-Cu SS)孵育后,探究了细胞和晶体之间的相互作用,并利用MTS和流式细胞仪分析评估了细胞响应。研究确认了COM处理后,316L-Cu SS能够抑制输尿管上皮细胞(UECs)的细胞凋亡。进一步的是, 研究人员通过蛋白免疫印迹分析和实时定量PCR技

草酸钙单水合物(COM)是结石的主要组成成分,并能够造成细胞膜损伤。另外,细胞损伤是COM晶体结合造成的主要事件。最近,有研究人员在含铜不锈钢(316L-Cu SS)孵育后,探究了细胞和晶体之间的相互作用,并利用MTS和流式细胞仪分析评估了细胞响应。

研究确认了COM处理后,316L-Cu SS能够抑制输尿管上皮细胞(UECs)的细胞凋亡。进一步的是, 研究人员通过蛋白免疫印迹分析和实时定量PCR技术(qPCR)Cu/Zn超氧化物歧化酶(CuZnSOD)的分子表达表明了316L-Cu SS能够抑制氧化胁迫,从而导致CuZnSOD表达的上调。更多的是,研究人员通过蛋白免疫印迹和qPCR调查了晶体粘附细胞因子CD44的表达,并利用酶联免疫印迹(ELISA)测量了相关的透明质酸(HA)的分泌情况。

最后,研究人员指出,所有的结果确定了316L-Cu SS孵育的细胞的相关表达均下调,表明了316L-Cu SS能够抑制晶体的粘附。
