The NSUN2-YBX1 axis enhances 5-Methylcytosine modification to facilitate NPM1-mediated nuclear translocation of PKM2, augmenting the Warburg effect and promoting nasopharyngeal carcinoma progression in a mouse model.

The NSUN2-YBX1 axis induces m5C modification of NPM1, leading to increased NPM1 stability and its expression. This upregulation facilitates the nuclear translocation of PKM2, which promotes aerobic glycolysis and drives the proliferation and metastasis of NPC. These findings highlight the potential of targeting NPM1 as a novel therapeutic approach for NPC.
