Up-regulation of MALAT1 in tumor tissues samples and cell lines. a The MALAT1 expression in 78 pairs of gastric cancer and corresponding non-cancerous gastric tissues was detected by qRT-PCR assays. **P < 0.05, the internal control was GAPDH. b Kaplan–Meier survival curve and log-rank test was perform to analyze the correlation between MALAT1 expression and the over survival (OS) time. c The MALAT1 expression in gastric cancer cells and an immortalized normal gastric epithelial cell line GES-1 was detected by qRT-PCR assays. **P < 0.05. d, e The MALAT1 expression in MKN45 or MKN28 cells was detected after knockdown of MALAT1 by qRT-PCR assays. Results were represented as the average ± SD based on 3 independent experiments. **P < 0.05
