ELOVL2 and glioblastoma: Here, finding of the association between high ELOVL2 expression in GBMs and worsened patient prognosis (Fig. 5a and Additional file 3: Figure S7F), coupled with the demonstrated requirement of ELOVL2 for GBM cells tumorigenicity in vivo, demonstrates a causal link between ELOVL2 and GBM growth.
