LINC00152 Knock-down Suppresses Esophageal Cancer by EGFR Signaling Pathway

AIM: This study aims to explain the role and mechanism of lncRNA LINC00152 in esophageal cancer. METHODS: 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. RESULTS: 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. CONCLUSION: 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.
