Abstract
BACKGROUND/AIM: MicroRNAs (miRNAs) are non-coding RNA molecules that exert post-transcriptional gene expression regulation in response to cellular or environmental changes. Genetic variation affects their synthesis and cellular actions, and single nucleotide polymorphisms (SNPs) are one example of genetic variants studied in relation to various diseases. Literature indicates that the differentially expressed miRNA-145 in patients' serum is an essential biomarker for abdominal aortic aneurysm (AAA). However, the correlation between specific miR-145 genetic polymorphisms with AAA susceptibility is inadequately studied. MATERIALS AND METHODS: Eighty-seven AAA patients and 122 healthy controls were recruited. Peripheral blood samples were genotyped for miRNA-145 SNPs; rs55945735, rs73798217 and rs353291. RESULTS: The GG genotype of the rs55945735 polymorphism (p=0.047) and the AG genotype of the rs353291 polymorphism (p=0.036) were overrepresented in AAA patients compared to healthy individuals, revealing an association with susceptibility to AAA development. CONCLUSION: SNPs rs55945735 and rs353291 are associated with AAA susceptibility.
