The Villin/Gelsolin/Fragmin Superfamily Proteins in Plants

Journal of Integrative Plant Biology 2007年第8期49卷 1183-1191页

作者： Hui Su Ting Wang Huaijian dong haiyun Ren (Key Laboratory of Cell Proliferation and Regulation Biology of Ministry of Education and College of Life Sciences Beijing Normal University Beijing 100875 China Key Laboratory of Cell Proliferation and Regulation Biology of Ministry of Education and College of Life Sciences Beijing Normal University Beijing 100875 China

The villin/gelsolin/fragmin superfamily is a conserved Ca^2＋-dependent family of actin-regulating proteins that is widely present both in mammalian and non-mammalian organisms. They have traditionally been characterized by the same core of three or six tandem gelsolin subdomains. The study in vertebrates and lower eukaryotic cells has revealed that the villin/gelsolin/fragmin superfamily of proteins has versatile functions including severing, capping, nucleating or bundling actin filaments. In plants, encouraging progress has been made in this field of research in recent years. This review will summarize the identified plant homologs of villin/gelsolin/fragmin superfamily, thus providing a basis for reflection on their biochemical activities and functions in plants.

目的:探讨长链非编码RNA(lncRNA)CASC9对高糖(HG)诱导的人肾小管上皮细胞损伤的影响和可能机制。方法:体外培养人肾小管上皮细胞HK-2,用25 mmol/L葡萄糖干预24 h,RT-qPCR法检测细胞中CASC9和miR-513a-5p表达。分别转染CASC9过表达载体、miR-513a-5p抑制剂或共转染过表达载体与miR-513a-5p模拟物至HK-2细胞,然后用25 mmol/L葡萄糖干预24 h,ELISA检测细胞培养上清中IL-6和TNF-α表达,流式细胞术检测细胞凋亡,Western blot检测细胞中cleavedcaspase3和cleaved-caspase9蛋白表达。双荧光素酶报告基因实验验证CASC9和miR-513a-5p的调控关系。结果:HK-2细胞经高糖处理后,细胞中CASC9的表达量减少(P<0.05),而miR-513a-5p的表达量增加(P<0.05)。上调CASC9或下调miR-513a-5p的HK-2细胞经高糖处理后,细胞培养上清中IL-6和TNF-α表达量减少(P<0.05),细胞凋亡率和细胞中cleaved-caspase3和cleaved-caspase9蛋白表达量降低(P<0.05)。CASC9可靶向结合miR-513a-5p,且上调CASC9抑制HK-2细胞中miR-513a-5p表达。上调miR-513a-5p逆转上调CASC9对高糖诱导的HK-2细胞培养上清中IL-6和TNF-α表达量及细胞凋亡率、cleaved-caspase3和cleaved-caspase9蛋白表达的影响。结论:上调CASC9可能通过靶向下调miR-513a-5p阻碍高糖诱导的人肾小管上皮细胞HK-2分泌炎症因子及细胞凋亡。
