Background
Colorectal Cancer is found one of the most profound type of cancer around globe, affecting men and women with different ethnic and racial groups. Insulin-like growth factor 1 is known as peptide growth factor found to increase the proliferation of cell and prevent apoptosis. Insulin pathway might have linked with progression of colorectal cancer.
Methods
This study conducted on total 160 subjects, including 80 patients with colorectal cancer with 80 age and gender match controls. Clinical parameters were compared between the control group and Colorectal cancer group. Blood serum IGF-1 was quantified by using ELISA and IGF-1 rs6214(C/T) variations were investigated using TaqMan allelic discrimination assay.
Results
Blood serum level of Insulin growth factor-I (ng/ml) showed substantial association concerning groups while IGF-1 rs6214(C/T) genotype distribution observed increased in colorectal cancer patients as compared to controls with significant association. The variant TT and CT genotype frequency observed more common in cases as compared to control. However, the wild type CC genotype were common in cases used to compared with controls. The Odds Ratio reveal the risk of variant IGF-1 rs6214 T allele to increase 3 times compared to wild type allele.
Conclusion
The homozygous TT genotypes and T variant allele of IGF-1 rs6214(C/T) showed association with high serum Insulin growth factor level 1, may increase susceptibility to the colorectal cancer. This work will use to investigate the associations between Insulin-like growth factor 1 and rs6214(C/T) gene variant and blood serum level with the vulnerability to treat Colorectal. In summary, we have investigated the relationship between Insulin growth factor level hormone and colorectal cancer. Further studies are required to understand the association between colorectal cancer and polymorphism. However, this study can be serve as an informative study to uncover mechanisms behind main cause of colon cancer. Therefore, the genomic profiling of Insulin-like growth factor-1 can be helpful to treat colorectal cancer patients.
