A novel tumor suppressor protein encoded by circular AKT3 RNA inhibits glioblastoma tumorigenicity by competing with active phosphoinositide-dependent Kinase-1. 3C Representative images showing plate colony formations from different cell lines were incorrectly selected during figure assembly; this affects circ-AKT3 IRES mut U373 (bottom left in left-hand colony formations), and circ-AKT3 shRNA control SW1783 and HS683 (top and bottom left in right-hand colony formations).
