To determine whether CXCR3 is expressed in colon carcinoma (CRC), we analysed by quantitative RT–PCR (real-time quantitative reverse transcription polymerase chain reaction) the expression levels of CXCR3 on surgical re-section pieces of human colon carcinoma and on corresponding healthy colon tissues. This evidence concerns the gene CXCR3 and colorectal carcinoma.
