BRSK1 and glioblastoma: Genes, namely, PPP2R2C (protein phosphatase regulatory subunit B gamma), SH3GL2 (SH3 domain-containing GRB2-like 2, endophilin A1), BRSK1 (BR serine/threonine kinase 1), DDN (dendrin), CACNA1E (calcium voltage-gated channel subunit alpha1 E), and MAPK8IP2 (mitogen-activated protein kinase 8 interacting protein 2) were harmoniously underexpressed in GBM than in the normal tissues.
