Carnosine is an endogenous dipeptide found in the vertebrate skeletal muscles that is usually obtained through the diet. To investigate the mechanism by which carnosine regulates the migration and intravasation of human colorectal cancer (CRC) cells, we used cultured HCT-116 cells as an experimental model in this study. We examined HCT-116 cell migratory and intravasive abilities and expression of epithelial-mesenchymal transition (EMT)-associated molecules and matrix metalloproteinases (MMPs) after carnosine treatment. The results showed that both migration and invasion were inhibited in cells treated with carnosine. We found significant decreases in Twist-1 protein levels and increases in E-cadherin protein levels in HCT-116 cells after carnosine exposure. Although plasminogen activator (uPA) and MMP-9 mRNA and protein levels were decreased, TIMP-1 mRNA and protein levels were increased. Furthermore, the cytosolic levels of phosphorylated I kappa B (p-I kappa B) and NF-kappa B DNA-binding activity were reduced after carnosine treatment. These results indicate that carnosine inhibits the migration and intravasation of human CRC cells. The regulatory mechanism may occur by suppressing NF-kappa B activity and modulating MMP and EMT-related gene expression in HCT-116 cells.
