| Abstract | Background: Breast cancer, as the most frequent cancer diagnosed in women worldwide, is affected by different regulatory mechanisms and cellular processes such as microRNAs (miRNAs) and autophagy, which influence tumor cell progression. MiRNAs play a crucial role in cancer progression. Aberrant miRNA expression has been described in various human cancers. Growing evidence proposes that miRNAs have a considerable role in tumor development and may constitute robust biomarkers for cancer diagnosis and prognosis. Objectives: The aim of this study was to evaluate miRNA-638 (miR-638) expression level in breast cancer patients and its bioinformatics analysis. Methods: In this case-control study, miR-638 expression was examined in fresh breast tissues of 47 patients with breast cancer using real time polymerase chain reaction (PCR). Then the role of miR-638 in various signaling pathways was studied using Target Scan, the MicroRNA-Target Interactions (miRTarBase) database, miRWalk2.0 and the database for annotation, visualization and integrated discovery (DAVID). Results: The miR-638 expression level showed a significant decrease in breast cancer patients. Also, this miRNA might be involved in apoptosis, angiogenesis, and autophagy. Conclusions: According to the results, miR-638 can be used as a potential prognostic biomarker for cancer growth, and its low expression is thought to increase cancer progression by disrupting cell death and autophagy, which are considered as important pathways in breast cancer. | en |
