This study aims to explain the role and mechanism of lncRNA LINC00152 in esophageal cancer.
The 30 pairs of esophageal cancer and adjacent normal tissues were collected and measuring the lncRNA LINC00152 expression by ISH and RT-qPCR assay. In the next cell experiment, Eca 109 and Kyse 150 cells were divided into 3 groups: NC group were treated with non-treatment; BL group were transfected with empty vector and lncRNA group were transfected with lncRNA LINC00152. The cells proliferation were measured by MTT assay; the cells apoptosis and cell cycle were evaluated by flow cytometry. The relative proteins expressions were measured by WB assay.
Compared with NC groups, the cell proliferation rate of lncRNA groups were significantly suppressed (P<0.05, respectively); the cell apoptosis and G1 phase rates were significantly enhanced in the lncRNA groups (P<0.05, respectively). In the proteins expressions, the EGFR, PI3K and AKT proteins expressions of lncRNA group were significantly inhibited and the P21 proteins expressions were significantly stimulated in the lncRNA groups compared with those of NC groups in Eca 109 and Kyse 150 cells.
The lncRNA LINC00152 had anti-tumor effects on esophageal cancer in the Eca 109 and Kyse 150 cells, the mechanisms were relative with EGFR pathway.
本研究旨在阐释长链非编码RNA LINC00152在食管癌中的作用及机制。
收集30对食管癌组织及癌旁正常组织,采用原位杂交(ISH)和逆转录定量聚合酶链反应(RT-qPCR)检测长链非编码RNA LINC00152的表达。在接下来的细胞实验中,将Eca 109和Kyse 150细胞分为3组:NC组不做处理;BL组转染空载体;lncRNA组转染长链非编码RNA LINC00152。采用MTT法检测细胞增殖;通过流式细胞术评估细胞凋亡和细胞周期。采用蛋白质免疫印迹法(WB)检测相关蛋白表达。
与NC组相比,lncRNA组细胞增殖率显著受到抑制(P均<0.05);lncRNA组细胞凋亡率和G1期比例显著升高(P均<0.05)。在蛋白质表达方面,与Eca 109和Kyse 150细胞中的NC组相比,lncRNA组中表皮生长因子受体(EGFR)、磷脂酰肌醇-3激酶(PI3K)和蛋白激酶B(AKT)蛋白表达显著受到抑制,而P21蛋白表达显著受到促进。
长链非编码RNA LINC00152对Eca 109和Kyse 150细胞中的食管癌具有抗肿瘤作用,其机制与EGFR通路相关。
