Abstract

Chronic inflammation and dyslipidemia are associated with an increase in the incidence of colorectal cancer (CRC). Serum C- reactive protein (CRP) and oxidized low-density lipoprotein (oxLDL), as Lectin-like oxidized low-density lipoprotein receptor-1 (LOX-1) ligands, increase during inflammation and dyslipidemia, respectively. To evaluate the effects of CRP on the expression of important genes involved in the development of CRC, the CRC cell line, LS174T, was treated with the commercial CRP. Based on the Real-time PCR data, in the presence of CRP, LOX-1, CEA, MMP1, and MMP2 mRNA expression significantly increased, compared to the control group. Moreover, in the presence of CRP, secretion, and expression of CEA in the cell lysate and conditioned media increased in a concentration-dependent manner. The results of flow cytometry showed that expression of LOX-1 receptors at the cell surface increased significantly in the presence of 10 mg/L of CRP. However, inhibition of LOX-1 receptors with a specific monoclonal antibody reduced the effects of CRP on protein/mRNA expression. In conclusion, Increased CRP level, can potentially elevate the expression of important genes in CRC by stimulating LOX-1 receptors.
