CEBPB and nonpapillary renal cell carcinoma: Analysis of CEBPB expression in 33 cancer types using data from TCGA and GTEx revealed significant overexpression in nine cancer types: breast invasive carcinoma (BRCA) (p < 0.001), colon adenocarcinoma (COAD) (p < 0.001), esophageal carcinoma (ESCA) (p < 0.001), glioblastoma multiforme (GBM) (p < 0.001), head and neck squamous cell carcinoma (HNSC) (p < 0.001), kidney renal clear cell carcinoma (ccRCC) (p < 0.001), kidney renal papillary cell carcinoma (KIRP) (p < 0.001), rectum adenocarcinoma (READ) (p < 0.001), and stomach adenocarcinoma (STAD) (p < 0.001) (Fig. 1B).
