The expression of chemokine monocyte chemoattractant protein-1 in colorectal carcinoma / 中华消化杂志

ABSTRACT

Objective To study the relationship between the expression of chemokines monocyte chemoattractant protein 1 (MCP 1) and the biological behavior of colorectal carcinoma by detecting chemokine mRNA and protein in human colorectal cancerous tissues. Methods The expression of the MCP 1 mRNA was detected in colorectal carcinoma collected freshly from surgical specimens by RT PCR and the expression of the MCP 1 protein was assessed in colorectal carcinoma tissues collected from surgical specimens by immunohistochemistry. Results All the 12 colorectal carcinoma expressed the MCP 1 mRNA, which was detected by RT PCR; MCP 1 protein was detected in 90% of the tumors; The expression of the MCP 1 protein in colorectal carcinoma was correlated with its state of metastasis and the Dukes' stage. Conclusions The expression of chemokine MCP 1 in colorectal carcinoma may influence its biological behaviour.
