High expression of APOO in malignant breast tissues is associated with poor prognosis in patients with BRCA. (A) Increased or decreased APOO in different tumor types from TCGA database were determined by TIMER. (B) APOO expression levels in BRCA and normal tissues. (C) APOO expression levels in BRCA and matched normal tissues. (D) APOO expression in BRCA tissues from HPA. (E) The ROC curve analysis of APOO in BRCA patients from TCGA database.
