Study the Effect of RAGE and HMGB1 Genes Polymorphism on Breast Cancer Susceptibility in Iraqi Female

Abstract

Background: The most frequent malignancy among women globally is breast cancer (BC). Breast lobules or ducts are the genesis of breast cancer, which is an uncontrolled development of epithelial cells. High mobility group protein box 1 (HMGB1) possesses both pro- and anti-tumorigenic bioactivities, which contribute to its complicated function in carcinogenesis. Damage associated Molecular Pattern molecules (DAMPs) generated following tissue injury include HMGB1, many S100 proteins, and others. RAGE is thought to be a receptor for these molecul
Aim of the study: The study was aimed to find the High mobility group protein box 1 (HMGB1) HMGB1 (rs1412125) and Receptor for Advanced Glycation End Products RAGE (rs1800624) genotypic and allelic frequency. Using Allele Specefic polymerase chain reaction AC-PCR and Polymerase Chain Reaction Restriction Fragment Length Polymorphism RFLP-PCR in BC patients and healthy controls, as well as their correlation with breast cancer susceptibility.
Material and methods :. Samples were taken at Marjan Cancer Hospital, Babylon. HMGB1 rs1412125 and RAGE rs18400624 polymorphisms were evaluated for patients and controls using the PCR-RFLP and allele-specific polymerase chain reaction (AS-PCR) method. SPSS software was used to perform the statistical analysis.
Results : There is non-significant difference between patients and control in TT, AA, and TA genotyping of (rs1800624) in RAGE gene (p=0.22), non-significant difference between patients and control in TT, TC, and CC genotyping of (rs1412125) in HMGB1 gene (p=0.09).
Conclusion : Our results showed no association between HMGB1 polymorphisms and RAGE and breast cancer risk.
