Abstract
Gastric cancer is the third most frequent cancer with high prevalence and mortality globally. Circular RNAs (circRNAs) play a key role in cancer regulation, including gastric cancer. Nevertheless, only a few circRNAs have been well elucidated in gastric cancer. Hence, we investigated the action of circ_0067514 on gastric cancer and clarified the underlying mechanism. Here, we found that circ_0067514 was decreased in gastric cancer patients and cancer cells. The circ_0067514 expression was correlated with gastric cancer overall survival, lymph node metastasis, tumor, node, metastasis (TNM) stage, and histological differentiation. Overexpression of circ_0067514 blocked proliferation, invasion, and glycolysis of gastric cancer cells. Besides, circ_0067514 regulated large tumor suppressor kinase 2 (LATS2) expression by absorbing microRNA (miR)-654-3p. Furthermore, circ_0067514 modulated gastric cancer aggressive behaviors and glycolysis via miR-654-3p/LATS2 axis. Moreover, circ_0067514 constrained tumor growth in vivo. Together, this study showed that circ_0067514 suppressed gastric cancer aggressive development and glycolysis via miR-654-3p/LATS2 axis, making circ_0067514 a valuable target for preventing gastric cancer progression.
