Abstract
Introduction: In women, breast cancer is a prevalent malignancy. One of the important genes in breast cancer progression is Pinin. LncRNAs H19 plays an important role in breast cancer cell development. In this study, the correlation between a miRNA-related rs532 polymorphism (G) and the level of expression of Pinin and lncRNA H19 in breast cancer tissues was investigated.
Methods: Tissue samples were collected from 64 patients with breast cancer. RT-PCR with highresolution melting (HRM) analysis was used.
Results: Our data suggest that there is significant up-regulation in the expression of lncRNA H19 and the Pinin gene in breast cancer tissue compared to the control ones. The Pinin polymorphism rs532 G is significantly associated with Pinin expression of breast cancer tissue compared to the control one.
Discussion: The rs532 G polymorphism is located around the pinin and its allele frequency is significantly associated with Pinin expression. Perhaps, rs532 G polymorphism could be functional in breast cancer progression through the impact on pinin expression. There is no correlation between SNP and lncRNA H19.
Conclusion: The polymorphism rs532 G polymorphism is significantly associated with Pinin expression of breast cancer tissue from Isfahan patients which suggests the miRNA-141has potential to regulate Pinin expression levels.
Keywords: Breast cancer, polymorphism, Pinin gene, LncRNA H19 gene, rs532, tumor.
