Abstract
AIM: To determine expression level of chemokine receptor 7 (CCR7) and explore its role in colorectal tumor pathogenesis.
METHODS: Immunohistochemistry was used to detect CCR7 protein in specimens. Expression of CCR7 mRNA was determined using reverse transcription PCR (RT-PCR). And Western blotting was used to detect CCR7 protein in colon cancer cells.
RESULTS: CCR7 mRNA expression was found in 45 colorectal cancer specimens and 12 cancer-adjacent normal tissues (χ2 = 34.44, P < 0.01). CCR7 protein expression was found in 34 colorectal cancer specimens and 6 cancer-adjacent normal tissues (χ2 = 28.51, P < 0.01). CCR7 mRNA and protein were expressed highly in colon cancer cell line SW-480, but lowly in HT-29.
CONCLUSION: CCR7 is involved in colorectal cancer pathogenesis and its expression in metastasis.
