MAP3K1 SNP rs889312 potential risk and MAP3K9 SNP rs11628333 menopause dependent association for breast cancer

Abstract

Abstract Objectives Breast cancer is the leading cause of mortality in today’s world. An alarming rise in cancer incidence has been observed in the South Asian region. The aberrant molecular mechanisms regulating cell proliferation and development contribute to cancer development. A better understanding of the detailed molecular mechanisms at genetic and epigenetic levels can help to treat breast cancer more efficiently. The present study is aimed to identify the possible association of MAP3K1 SNP rs889312 and MAP3K9 rs11628333 in breast cancer in the South Asian region. Materials and methods Female breast cancer patients were recruited in the study. DNA was isolated from the blood samples collected from the patients. PCR-RFLP was used for genotyping, and data analysis was done by SPSS software. Results Genotyping data for MAP3K1 SNPrs889312 showed statistically significant association with breast cancer, while MAP3K9 SNPrs11628333 showed characteristic association of rare allele heterozygote’s and homozygotes in pre and post-menopausal patients, respectively. Conclusion The study concludes a strong association of the rs889312 with breast cancer in the Pakistani population and a characteristic association of unique genotypes TC and CC in pre- and post-menopausal breast cancer patients. These findings can provide a ready tool as a breast cancer marker in south Asian populations.
