ABSTRACT
As a highly malignant gastrointestinal tumor, pancreatic cancer is highly invasive and metastatic, which leads to the low overall survival rate of patients with pancreatic cancer. Studies have shown that long non-coding RNA (lncRNA) is involved in the development, progression, invasion, and metastasis of pancreatic cancer through epigenetic, transcriptional or post-transcriptional regulation. Dysregulated expression of lncRNA is observed in pancreatic cancer and induces epithelial mesenchymal transition (EMT) through specific regulatory mechanisms, thereby causing the changes in the biological behavior of tumor cells. This article reviews the mechanisms of lncRNA in promoting EMT, regulating tumor biological function as competing endogenous RNA, and affecting the development, invasion, and metastasis of pancreatic cancer via multiple pathways by regulating the ferroptosis, autophagy, and exosome of tumor cells, in order to provide a theoretical basis and new targets for the early diagnosis and treatment of pancreatic cancer.
