Importance of PKCδ signaling in fractionated-radiation-induced expansion of glioma-initiating cells and resistance to cancer treatment

Abstract excerpt

Brain tumors frequently recur or progress as focal masses after treatment with ionizing radiation. However, the mechanisms underlying the repopulation of tumor cells after radiation have remained unclear. In this study, we show that cellular signaling from Abelson murine leukemia viral oncogene homolog (Abl) to protein kinase Cδ (PKCδ) is crucial for fractionated-radiation-induced expansion of glioma-initiating...
