RNF113A as a poor prognostic factor promotes metastasis and invasion of cervical cancer through miR197/PRP19/P38MAPK signaling pathway.

ABSTRACT

It has been discovered that aberrant expression of RNF113A plays a significant role in various diseases, including esophageal cancer, hepatocellular carcinoma, and X-linked trichothiodystrophy syndrome. Nevertheless, its functional implications in cervical cancer (CC) remain unclear. The objective of this study was to investigate the role of RNF113A in both the development and prognosis of CC. To achieve this objective, a total of sixty cases were included in the follow-up investigation. The findings revealed a significant up-regulation of RNF113A protein in CC tissues compared to paired paracancerous tissues, and a high expression level of RNF113A was strongly associated with malignant phenotypes such as lymph node metastasis, differentiation degree, depth of invasion, and FIGO stage. Meanwhile, RNF113A was found to be an independent prognostic risk factor, with its high expression significantly correlating with a reduced overall survival period in patients. To elucidate the underlying cause and mechanism of the unfavorable prognosis associated with RNF113A, comprehensive functional investigations were conducted both in vitro and in vivo.Interestingly, it was revealed that RNF113A promoted migration and invasion while inhibiting apoptosis of CC cells, thereby contributing to a poor prognosis. Mechanistically, RNF113A regulated the progression and prognosis of CC through the miR197/Prp19/p38Mark signaling pathway. Overall, our findings underscore the potential clinical significance of RNF113A as an unfavorable prognostic factor in CC.
