The Expression of Formyl Peptide Receptor 1 is Correlated with Tumor Invasion of Human Colorectal Cancer.

ABSTRACT: Formyl peptide receptors (FPRs) are G protein-coupled chemoattractant receptors expressed mainly in phagocytic leukocytes. High expression of FPRs has also been detected in several cancers but the functions of FPR1 in tumor invasion and metastasis is poorly understood. In this study, we investigated the expression of FPRs in primary human colorectal cancer (CRC) and analyzed the association of FPRs expression with clinicopathological parameters. The levels of FPRs mRNA, especially those of FPR1, were significantly higher in colorectal tumors than in distant normal tissues and adjacent non-tumor tissues. FPR1 mRNA expression was also associated with tumor serosal infiltration. FPR1 protein expression was both in the colorectal epitheliums and tumor infiltrating neutrophils/macrophages. Furt
