| Abstract | Background: Colorectal cancer (CRC) is a major global health concern, and the link with Fusobacterium nucleatum has received considerable attention. Objectives: This study aimed to explore the prevalence of F. nucleatum and to assess the expression of the msh2, mlh1, and msh6 genes in CRC patients compared to a control group using real-time PCR. Methods: Forty CRC patients and twenty individuals from a control group participated in this study. Gastroenterologists collected biopsy specimens from which DNA and RNA were extracted using a specialized tissue extraction kit. Complementary DNA (cDNA) was then synthesized. Real-time PCR was employed to evaluate the expression levels of the msh2, mlh1, and msh6 genes and the presence of the F. nucleatum-specific 16srRNA gene to determine the relative prevalence of this bacterium in each group. Results: Results indicated a higher prevalence of the F. nucleatum-specific 16srRNA gene in CRC patients than in the control group. Additionally, expression levels of the msh2, mlh1, and msh6 genes were significantly higher in the cancer group, suggesting their role in CRC pathogenesis. The distribution of F. nucleatum was particularly high in the sigmoid and rectum areas of the colon. Conclusions: This study underscores the significance of F. nucleatum in CRC and provides insights into its association with altered gene expression patterns. Understanding the prevalence of F. nucleatum and its impact on msh2, mlh1, and msh6 genes may aid in developing improved diagnostic and therapeutic strategies for CRC. Further research is necessary to elucidate these relationships more comprehensively. | en |
