Epigenetic Control of Fatty-Acid Metabolism Sustains Glioma Stem Cells.

In this issue of Cancer Discovery, Gimple and colleagues examine superenhancers in glioblastoma and glioma stem cells (GSC), identifying one which promotes expression of ELOVL2, an enzyme in polyunsaturated fatty acid (PUFA) synthesis. They find that ELOVL2 products help maintain cell membrane organization and EGFR signaling in GSCs, and that targeting PUFA metabolism along with EGFR offers a potential novel therapeutic strategy for glioblastoma.See related article by Gimple et al., p. 1248.
