Abstract

With the continuous progress in modern medicine, the early detection rate of gastric cancer has increased, and the mortality rate has decreased. However, gastric cancer remains the third leading cause of cancer-related death worldwide, with a high recurrence rate. Metastasis is the leading cause of death and recurrence of gastric cancer, which greatly hinders treatment success. Cancer development is a complex process involving multiple sequential steps. In the metastatic cascade, local invasion may be considered an initial, crucial step in the development of a malignant tumor, which leads to distant metastasis. Epithelial-mesenchymal transformation (EMT) is one of the most important developmental processes that occur during tumor invasion. EMT confers certain basic abilities to cancer cells, such as migration, invasion and anti-apoptotic ability, thus initiating and increasing metastasis. However, little is known about the molecular mechanisms that promote EMT and gastric cancer cell metastasis. A number of recent studies have found that circular RNAs(circRNAs)are associated with gastric cancer EMT, regulating the EMT process and promoting the occurrence and development of tumors. Because of their unique continuous circular structure, circRNAs have relatively high stability in plasma and cells, making them more suitable as diagnostic biomarkers in malignant tumors. Therefore, understanding the mechanism of circRNAs in EMT in gastric cancer is an important research direction to actively prevent tumor metastasis and improve the therapeutic effect on advanced malignant tumors.
