The positive expression of BTRC is stronger in CRC than in normal tissues. a BTRC transcripts in normal tissues (N) and tumor tissues (T) of READ and COAD from TCGA data. TPM: transcripts per million. n.s. = no significance. b The representative IHC pictures of BTRC protein expression in colon normal tissues and CRC tissues by the Human Protein Atlas. Scale bar is 200 μm (upper) and 100 μm (lower). The single arrowheads point to the positive intensity of BTRC in normal colon tissues, and the double arrowheads point to the positive intensity of BTRC in colon adenocarcinoma. BTRC expression in colon adenocarcinoma was lower than in colon normal tissues. c ImageJ was used to analyze the relative mean gray values of BTRC protein expression in IHC pictures of colon normal tissues (n = 3) and colon adenocarcinoma (n = 3) which were normalized to the corresponding mean gray values of stromal tissues in each IHC picture from the Human Protein Atlas. Relative gray value = (The intensity of BTRC expression in normal colorectal epithelium or colorectal tumor)/The intensity of BTRC expression in colorectal stromal cells. *p < 0.05
