Cel badania: Oceniono związek pomiędzy występowaniem wariantów dwóch polimorfizmów pojedynczego nukleotydu -2518 A/G MCP-1 oraz 190 G/A CCR2 z rakiem jelita grubego (RJG). Materiał i metody: Do badania włączono pacjentów z różnym stopniem zaawansowania RJG oraz osoby zdrowe. Genotypy oznaczono metodą reakcji łańcuchowej polimerazy – polimorfizmu długości fragmentów restrykcyjnych (RFLP-PCR). Wyniki: Zaobserwowano związek pomiędzy rakiem jelita grubego i genotypem GG polimorfizmu -2518 G/A MCP-1. Nie zaobserwowano natomiast istotnej statystycznie korelacji pomiędzy RJG a polimorfizmem 190 A/G CCR2. Wnioski: Wyniki tego badania potwierdzają hipotezę, że polimorfizm w promotorze genu MCP-1 może przyczyniać się do rozwoju raka jelita grubego.

The aim of the study: We evaluated the connection between the presence of the -2518 A/G MCP-1 as well as 190 G/A CCR2 polymorphic variants and colorectal cancer (CRC) occurrence. Material and methods: Study group consisted of subjects with different stages of CRC as well as healthy controls. Genotypes were determined by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method. Results: W observed an association between the colorectal cancer and the GG genotype of the -2518 A/G MCP-1 single nucleotide polymorphism. No statistically significant correlation was found between CRC and the 190 G/A CCR2 polymorphism. Conclusion: The results of this study support the hypothesis that polymorphism in the MCP-1 gene may contribute to the etiology of colorectal cancer.

Inflammatory bowel diseases (IBD) are disorders originated from immune disturbances. The aim of the study was to evaluate the association between the -2518 A/G MCP-1 polymorphism and the risk of IBD development. Material and methods. Genotypes were determined by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method. Study group consisted of 197 subjects with IBD (120 with ulcerative colitis and 77 with Crohn’s disease) as well as 210 healthy controls. Results. The presence of the -2518 G/G MCP-1 genotype in the investigated groups seems to be connected with higher risk of inflammatory bowel disease as well as Crohn’s disease only (OR 2.26; 95% CI 1.44-3.54 and OR 2.08; 95% CI 1.21-3.46, respectively). Conclusions. Our data showed that the -2518 A/G MCP-1 polymorphism might be associated with the IBD occurrence and might be used as predictive factor of these diseases in a Polish population.
