FIGURE 1.
Elevated plasma glycogen phosphorylase BB (GPBB) concentrations in high-grade glioma patients with TMZ resistance compared to those with TMZ sensitivity. Plasma GPBB concentration was measured before surgery. (A) Plasma GPBB concentration in toto, TMZ-sensitive and TMZ-resistant cohorts. (B) Plasma GPBB concentration in IDH1 mutant and IDH1 wild cohorts. (C) Plasma GPBB concentration in MGMT methylation and MGMT non-methylation cohorts. (D) Plasma GPBB concentration in 1p/19q co-deletion and 1p/19q wild cohorts. (E) ROC curve analysis of plasma GPBB concentration in response to TMZ. All values are expressed as means ± SEM, indicated by vertical bars. ∗Indicates a statistically significant (P < 0.05) difference from TMZ-sensitivity group. (F) Survival curve showing overall survival (OS) for high-grade glioma patients with high levels or low levels of plasma GPBB.
