670-Evolution of IDH-Mutant Glioma Progression
This research investigates how IDH-mutant gliomas transform from slow-growing tumors into aggressive, fatal malignancies. By comparing single-cell gene expression and chromatin accessibility, the authors found that these tumors start as indolent cells resembling oligodendrocyte progenitors (OPCs) fueled by epigenetic changes like DNA hypermethylation. As the disease progresses, the tumors shift toward a proliferative state resembling neural progenitor cells (NPCs) that share a similar epigenetic landscape but enact different genetic programs. This transition is marked by a loss of global DNA…
