Expression and prognostic characteristics of m 5 C regulators in low-grade glioma

Glioma is the most common intracranial malignant tumour. A clear diagnosis and molecular targeted therapy are of great significance for improving the survival time and quality of life of patients with low-grade glioma. 5-methylcytosine methylation is one of the ways of RNA modification, but there are limited studies on the role of m C methylation of low-grade glioma. Single-nucleotide variant, RNA expression matrix and corresponding clinical data of low-grade glioma came from public database. The single-nucleotide variant and expression of m C regulators were estimated. A prognostic model based on m C regulators was constructed by Cox regression. Potential functions of these molecules were assessed by gene set enrichment analysis. DNMT3A mutation was the most frequent among the m C regulators in low-grade glioma. NSUN3, TET2, TRDMT1, ALYREF, DNMT3B, DNMT1, NOP2 and NSUN2 were up-regulated. One prognostic model was constructed which had a strong predictive power for the overall survival of low-grade glioma. We studied the expression and prognostic characteristics of m C regulators in low-grade glioma, supplied biomarkers for the diagnosis and prognosis and provided the foundation for the study of the pathogenesis of low-grade glioma.
