Activation of the mitogen‐activated protein kinase (MAPK) signaling pathway, which includes c‐Jun NH2‐terminal kinase (JNK), the p38 MAPK, and the extra‐cellular signal‐related kinase (ERK), has been implicated in the development and progression of HGGs, including GBM (3). Here, MAPK8 is linked to glioblastoma.
