Gastric cancer is one of the main malignancies threatening human health, and its occurrence involves multistep and multigene interactions. Epithelial-mesenchymal transition (EMT) is a biological process in which epithelial cells transform to mesenchymal phenotypic cells through specific procedures. Studies have shown that long non-coding RNAs (lncRNAs) can promote or inhibit EMT by binding to target proteins and competing microRNAs as competitive endogenous RNAs, and some specific EMT-related lncRNAs are deeply involved in the invasion and metastasis of gastric cancer. In this review, we summarized the recent mechanisms of EMT-related lncRNAs in the regulating the invasion and metastasis of gastric cancer.
