Abstract:
Aim: MicroRNAs (miRNAs) are small regulatory RNA molecules that control gene activity by base pairing with target messenger RNA leading to their cleavage or translational repression. Previous studies show an involvement of miRNAs in various diseases including cancer. Members of the Mir-23a cluster (MIR23A, MIR24–2 and MIR27A) are involved in breast cancer (BC). Methods: In the present study, miR-23a/24-2/27a cluster was screened for genetic mutation in BC patients. Results: Heterozygous (A/G allele) as well as homozygous (G/G allele) variants were found in mir-27a gene in screened BC patients. RNA structural analysis revealed that the single nucleotide polymorphism (SNP) effects the size of the terminal loop in the precursor miRNA (pre-miRNA). Conclusion: The altered (G allele) hairpin structure observed was two bases longer than the reference (A allele) hairpin.
