The Role of NSUN Family Genes in m5C Methylation and Diseases.

ABSTRACT: 5-Methylcytosine (m5C) methylation is a widely present nucleic acid modification in various RNAs and is a reversible epigenetic modification that affects RNA stability, nuclear export, and translation processes. Methylation writers are responsible for adding methyl groups to RNA molecules, regulating gene expression and cellular function through catalyzing methyl transfer reactions. In order to more intuitively demonstrate the important value of NOL1/NOP2/SUN domain (NSUN) family genes in both tumor and non-tumor diseases, we conducted a relevant review. The NSUN family genes (NSUN1/NOP2, NSUN2, NSUN3, NSUN4, NSUN5, NSUN6, NSUN7) are the main writers of m5C methylation. These genes can regulate methylation and affect the expression of other genes and are important in tumor and non-tumor di
