Abstract

Increasing evidence proves that circular RNAs (circRNAs) play an important role in regulating the biological behaviors of tumors. The central purpose of this research was to investigate the functions of circRNA in gastric cancer. The utilization of real-time PCR was to test circPTN expression in gastric cancer cells. Cell counting colony formation assays, CCK-8 assay, and EdU assay were used to investigate proliferation. Transwell assay was applied to investigate migration. We discovered that circPTN was highly expressed in gastric cancer cells. Low expression of circPTN inhibits gastric cancer cell proliferation and migration. Elevated expression of circPTN promotes gastric cancer cell proliferation and migration. Moreover, we discovered that circPTN could accelerate self-renewal and increase the expression of stemness markers. The results of our study suggested that a high level of circPTN expression promotes the proliferation and stemness of gastric cancer cells.
