ABSTRACT
Gastric cancer is one of the most common malignant tumors in the world, and EMT plays a key role in the development and metastasis of gastric cancer. The regulation of EMT is a complex network. Transcription factors such as SNAIL/SLUG, Twist1/2 and ZEB1/2 play an important induction role in the process of tumor EMT. In addition, the regulation of EMT is related to the participation of cytokines and miRNAs (such as miR-200 family). In recent years, with the deepening studies on non-coding RNAs, researchers discovered that ceRNA networks, involving lncRNA, circRNA, miRNA, mRNA and other RNA molecules, can extensively regulate the proliferation and metastasis of tumor cells, and are closely related to EMT. This paper reviews the role and molecular mechanism of lncRNA as ceRNA in EMT of gastric cancer, to deepen the understanding of ceRNA network in gastric cancer and other malignant tumors.
