The Association of the MTHFR Gene Polymorphisms with Breast Cancer Susceptibility
نویسندگان
چکیده مقاله:
Introduction: Breast cancer is the most common malignancy in women worldwide. It is also the second leading cause of cancer death among women after lung cancer. Considering the relationship among plasma folate levels, the level of uracil, and DNA damage in cell division, methyl tetrahydrofolate reductase (MTHFR) is a suitable candidate for studies on the susceptibility to cancer, including breast cancer. This study aimed to investigate the relationship between two polymorphisms in the MTHFR gene and the risk of breast cancer among women in Markazi Province, Iran. Material & Methods: This case-control study investigated the rs1801131 and rs1801133 polymorphisms of the MTHFR gene and breast cancer risk in a large population including 80 patients and 80 healthy women in Markazi Province, Iran, using the PCR-RFLP technique. The specimens were genotyped by agarose gel electrophoresis. Finally, the data were analyzed in SPSS software (version 26). (Ethic code: Ir.arakmu.rec.1396.25) Findings: There was a statistically significant difference between the two groups of patients and controls regarding three genotypes of the rs1801133 locus (P=0.006). Moreover, the CT genotype (P=0.001, OR=2.471, 95% CI=1.229-4.965) and total TT and CC genotypes (P=0.000, OR=3.375, 95% CI=1.716-6.637) were significantly associated with the risk of breast cancer. However, the TT genotype (P=0.538) showed a protective role against breast cancer. In contrast, there was no statistically significant difference between the two groups of patients and controls in terms of three genotypes of the rs1801131 locus (P=0.149), which is consistent with the results of some studies. Discussion & Conclusion: The rs1801133 polymorphism of the MTHFR gene can be used as a marker in clinical prognostic studies related to the risk of breast cancer.

Background: Breast cancer is one of the most common worldwide malignancies among women. Biological data suggest that damage induced by endogenous and exogenous factors affects the integrity of DNA and associated with susceptibility to breast cancer. Single nucleotide polymorphisms (SNPs) in DNA repair genes can associated with differences in the repair efficiency of DNA damage and may affect br...

Association between MTHFR gene polymorphisms (C677T, A1298C) and genetic susceptibility to prostate cancer: a meta-analysis.
Genetic polymorphisms (C677T and A1298C) in methylenetetrahydrofolate reductase (MTHFR) were shown to be related to prostate cancer risk in previous studies; however, the results are controversial. We performed a meta-analysis of previous studies and quantitatively estimated these associations. Pubmed, Embase, and Cochrane Library Database were searched for published case-control studies evalua...
