The authors demonstrate that carnitine palmitoyltransferase 1A (CPT1A) expression is reduced in glioma stem cells (GSCs) in comparison with non-stem tumor cells. CPT1A overexpression promotes mitochondrial fusion and GSC differentiation by increasing the phosphorylation of dynamin-related protein 1 (Drp1) at Ser-637, thus impairing GSC-derived xenograft growth and prolonging survival in tumor-bearing mice. These results suggest that CPT1A could be a molecular target for GSC differentiation therapy.
