NUP37 promotes the proliferation and invasion of glioma cells through DNMT1-mediated methylation.

Nuclear regulation has potential in cancer therapy, with the nuclear pore complex (NPC) serving as a critical channel between the nucleus and cytoplasm, playing a role in regulating various biological processes and cancer. DNA methylation, an epigenetic modification mediated by DNA methyltransferases (DNMTs), influences gene expression and cell differentiation, and is crucial for the development and progression of tumor cells. Gliomas are the most common primary brain tumors, with glioblastoma being particularly aggressive, characterized by invasiveness, migration capability, and resistance to conventional treatments, resulting in poor prognosis. Our study revealed that the expression level of NUP37 affects the proliferation and invasion of glioma cells, and that the overexpression of DNMT1 can alleviate the adverse effects caused by NUP37 depletion. These findings suggest that NUP37 promotes the proliferation and invasion of glioma cells through its interaction with DNMT1.
