Abstract

Uterine corpus endometrial carcinoma (UCEC) is one of the most common gynecological malignancies, with an annually increasing incidence and a poor prognosis. lncRNAs and MicroRNAs regulate the progression of UCEC through ceRNA networks. Additionally, m6A modification plays various roles in UCEC, and abnormal regulation of it can directly affect tumor progression. However, the role of m6A-associated ceRNA networks in UCEC remains unclear. This study showed that the AC074117.1/miR-193a-3p axis promoted the malignant progression of UCEC through ALKBH5, an m6A demethylase. MeRIP assay indicated that ALKBH5 regulated m6A modification in UCEC. Gene set enrichment analysis and cell proliferation and migration assays showed that the AC074117.1/miR-193a-3p/ALKBH5 axis regulated the proliferation and migration of UCEC cells. With regard to mechanistic analysis, dual-luciferase reporter assay demonstrated that AC074117.1 acted as a ceRNA for miR-193a-3p, influencing the expression of ALKBH5. Furthermore, rescue experiments validated that the regulatory effects of miR-193a-3p on the malignant progression of UCEC relied on ALKBH5 to some extent. Altogether, this study revealed an m6A-related ceRNA network in UCEC, which may serve as a target for early diagnosis and treatment.
