To explore the correlation of expression of long non-coding RNA (lncRNA) zinc finger E-box binding homeobox 2 antisense RNA 1 (ZEB2-AS1) in gastric cancer tissues, analyze the correlations of its expression level with the clinicopathological features of gastric cancer and the malignant phenotype of tumor cells, and investigate the molecular mechanism of action of ZEB2-AS1 in gastric cancer.
