摘要: 目的 探索环状 RNA PRKCI (circular ribonucleic acid PRKCI, CircPRKCI) 通过 miR-101-3p / 转化生长因子 βⅢ 型受体 ( transforming growth factor beta type Ⅲ receptor, TGFBR3) 轴对食管鳞状细胞癌 ( esophageal squamous cell carcinoma, ESCC) 细胞恶性行为学的影响方法 si-NC、 si-CircPRKCI、 miRNC、 miR-101-3p mimics、 vector + miR-101-3p mimics、 CircPRKCI + miR-101-3p mimics 转染至 KYSE150 细胞中, 采用实时荧光定量 PCR ( Real-time quantitative PCR, RT-qPCR) 法检测细胞 CircPRKCImiR-101-3pTGFBR3 mRNA 表达并采用 RT-qPCR、 细胞计数试剂盒 8 ( cell counting kit-8, CCK-8) 、 Transwell 流式细胞术蛋白质印迹法检测各组细胞恶性行为情况结果 CircPRKCI TGFBR3 mRNA KYSE150细胞中上调, miR-101-3p 表达下调 (P< 0. 05); 沉默 CircPRKCI 能够靶向上调 miR-101-3p, 抑制 TGFBR3 表达以及细胞活力侵袭与迁移能力, 增强细胞凋亡 (P< 0. 05); 上调 miR-101-3p 能够显著抑制 KYSE150 细胞恶性行为, 而过表达 CircPRKCI 会减弱上调 miR-101-3p KYSE150 细胞恶性行为的抑制作用 ( P < 0. 05)。 结论 CircPRKCI 可通过靶向负调节 miR-101-3p / TGFBR3 , 影响 ESCC 细胞的增殖迁移侵袭与凋亡等恶性生物学行为

Abstract:

Objective To explore the impact of circular RNA PRKCI (CircPRKCI) on malignant behavior of esophageal squamous cell carcinoma (ESCC) cells through the miR-101-3p / transforming growth factor beta type Ⅲ receptor ( TGFBR3) axis. Methods si-NC, si-CircPRKCI,miR-NC, miR-101-3mimics, vector + miR-101-3mimics, and CircPRKCI miR-101-3mimicswere transfected into KYSE150 cells, RT-qPCR was used to detect the mRNA expression levels ofCircPRKCImiR-101-3and TGFBR3 in cells. RT-qPCR, cell counting kit-8 (CCK-8) method,transwell assay, flow cytometry, and Western blotting were used to detect the malignant behavior ofcells in each group. Results CircPRKCI and TGFBR3 mRNA were upregulated and miR-101-3expression was downregulated in KYSE150 cells (< 0. 05). Silencing CircPRKCI was able to target and upregulate miR-101-3and to inhibit TGFBR3 expression as well as cell viability, and cell invasive and migratory capacity, and to enhance the cell apoptosis (< 0. 05). Up-regulation of miR- 101-3significantly inhibited the malignant behavior of KYSE150 cells, whereas the overexpression of CircPRKCI attenuated the inhibitory effect of up-regulation of miR-101-3on the malignant behavior of KYSE150 cells (P<0.05). Conclusion CircPRKCI can target and negatively regulate the miR-101-3p/TGFBR3 axis to affect malignant biological behavior such as proliferation, migration, invasion and apoptosis of ESCC cells.
