CSIG-22. A CD133-Akt-Wnt SIGNALING AXIS PROVIDES FUNCTIONAL INSIGHT INTO THE ROLE OF CD133 IN GLIOBLASTOMA BRAIN TUMOR-INITIATING CELLS

Abstract Current transcriptional profiles of adult glioblastoma (GBM) recognize the activation of distinct signaling programs. Single-cell sequencing efforts have provided greater resolution of core developmental pathways implicated in disease progression and relapse. Of note, the Wnt pathway is activated in a subset of patients, despite the lack of recurrent activating mutations in human GBM. Given the description of CD133 as a marker of …
