The REMBRANDT database was then used to analyze the survival of glioblastoma patients (n=181) based on expression of executioner caspase genes (CASP3, CASP6 and CASP7 for the caspase-3, -6, and -7 proteins) and initiator caspase genes (CASP8, CASP9 and CASP10 for the caspase-8, -9, and -10 proteins). Here, CASP9 is linked to glioblastoma.
