Researchers identify source of a brain cancerβs deadly transformation
Slow-growing glioma tumors become more aggressive when their cells shift identities and acquire new genetic mutations.
New research from @jingyiwu.bsky.social, @drbradb.bsky.social, @suvalab.bsky.social, and others shows how slow-growing brain tumors called gliomas turn aggressive and deadly. The team pinpointed genetic shifts that push these tumors into the fast lane. #Science

6/We speculated this modelβwhere epigenetic events drive early clonal expansion and immune evasion, allowing tumors to progress until they acquire genetic mutationsβmay apply broadly across human cancers.

5/It also explains the distinct clinical behaviors of low- and high-grade IDH-mutant gliomas, including why low-grade tumors respond to IDH inhibitors, while high-grade ones do not.

4/This suggests that IDH mutations and hypermethylation suppress interferon (IFN) responses, which are crucial for the survival of these gliomas.

3/We also found these tumors initially depend on an epigenetic driver, DNA methylation, but later shift to genetic drivers, such as the deletion of tumor suppressors and interferon pathway genes.

2/ This suggests that IDH-mutant gliomas may begin with transforming OPCs into malignant OPC-like cells, followed by reprogramming into a highly proliferative NPC-like state.

1/We found that low-grade tumors primarily comprise cells resembling slow-proliferating oligodendrocyte precursor cells (OPCs), while high-grade tumors are dominated by cells resembling fast-proliferating neural progenitor cells (NPCs).
