The expression levels of both RBBP4 and RBBP7 were significantly higher in several cancers, including stomach adenocarcinoma, breast cancer, glioblastoma multiforme, cholangio carcinoma and liver hepatocellular carcinoma, compared with the normal tissues (P-value cut-off ≤ 0.01) (Supplemental Figure S5A; Supplemental Table S12 for TCGA abbreviations). This evidence concerns the gene RBBP4 and breast carcinoma.
