Increased expression of circERBB2 indicates worse prognosis of GBC patients. a CircERBB2 expression level was determined by FISH. b Survival probability was calculated with Kaplan-Meier survival analysis. Increased expression of circERBB2 indicated worse prognosis of GBC patients (n = 149). c circERBB2 showed significantly positive correlation with PA2G4 in GBC tissues, but not in para-cancer tissues (n = 28). d Proposed model of the circERBB2-PA2G4-TIFIA complex in upregulating rDNA transcription and GBC progression
