Due to its late detection and limited sensitivity to radiotherapy and chemotherapy, the 5-year survival rate is less than 5%. With the advancement of science and technology, the critical role of miRNA in cancer has been confirmed. miRNA has rapidly emerged as promising targets for the development of novel anti-cancer therapies. Among them, miR-107 and its potential downstream target gene ZFPM2 have been found to be associated with various cancers, but research on their roles in pancreatic cancer remains limited. They hold potential value for improving the current challenges in early detection and treatment of pancreatic cancer. This article reviews the existing research on miR-107 and ZFPM2 in other tumors, aiming to provide new insights for early detection and targeted therapy of pancreatic cancer.展开更多
