IDH1 and glioblastoma: In addition, we also compared the survival of GBM patients with wild-type IDH between the patients with low 6PGD pY481 scores and the patients with high 6PGD pY481 scores, which showed that 6PGD Y481 phosphorylation could also separate these patients into good- and poor-prognostic groups (Supplementary Fig. 6e).
