Fig. 2From: System-based approaches as prognostic tools for glioblastomaAssessment of the prognostic significance of single proteins regulating caspases-dependent apoptosis. a-e Kaplan-Meier estimates for Apaf-1 (a), Procaspase-9 (c), SMAC (d) and XIAP (e) showed no statistical significant differences in PFS curves among patients grouped by protein expression (>median vs. ≤median, in black and gray, respectively). Patients expressing higher concentrations of Procaspase-3 (>median) had longer PFS compared to those with low levels (≤median), (log-rank P = 0.049, b)Back to article page
