PRKDC and glioma: In this study, we reported that the p-DNA-PKcs (S2056) was significantly elevated in glioma compared with adjacent normal brain, and such a high level of phosphorylated DNA-PKcs tightly associated with malignancy of glioma, including clinical stage and the survival time of glioma patients, collectively demonstrating a pivotal role of DNA-PKcs in the progression of glioma.
