m 1 A Regulator TRMT10C Predicts Poorer Survival and Contributes to Malignant Behavior in Gynecological Cancers

N1-methyladenosine (m¹A) is an important post-transcriptional modification in RNA, and plays critical roles in cellular functions. However, the relationship between m¹A regulators and clinical significance of gynecological cancers remains unknown. In this study, we systematically analyzed RNA-seq and clinical data from several public database. Cell proliferation and migration assays were performed to verify the function of the m¹A writer TRMT10C in cancer cells. We observed genetic alterations and dysregulated expressions of m¹A regulators in gynecological cancer samples. We demonstrated that several m¹A regulators could serve as prognostic biomarkers for gynecological cancer patients. The high correlations among the expression of m¹A, N6-methyladenosine (m⁶A), and 5mC regulators were also revealed. Gene set enrichment analysis indicated that the mechanism of TRMT10C in regulating tumorigenesis was related to a variety of cancer-related pathways. Moreover, silencing TRMT10C suppressed the proliferation, colony formation, and migration of ovarian cancer and cervical cancer cells. In summary, our results highlight the importance of m¹A regulators in regulating oncogenesis, and indicate that targeting specific m¹A regulators might be a potential therapeutic strategy for gynecological cancers.
