  • Introduction: Breast cancer is one of the most common cancers among women, and early diagnosis plays a key role in improving the prognosis of the disease. In recent years, non-coding RNAs, including circRNAs and miRNAs, have emerged as potential biomarkers for cancer diagnosis and prognosis. circ_0000745 (SPECC1) and hsa-miR-145-5p are two important molecules involved in the regulation of genes related to breast cancer, which may play critical roles in cell proliferation and cancer progression.
  • Methods: In this study, tumor tissue and normal tissue samples were collected from patients with breast adenocarcinoma. Total RNA was extracted from tissue samples, and cDNA synthesis was subsequently performed. The expression levels of circ_0000745 and hsa-miR-145-5p were then assessed using qRT-PCR. Additionally, the relationship between the expression of these RNAs and the clinical characteristics of the patients was examined.
  • Results: The findings revealed a significant upregulation of circ_0000745 in cancerous tissues compared to normal tissues. In contrast, hsa-miR-145-5p was significantly downregulated in tumor tissues. These results suggest a potential role for these two molecules in regulating processes related to cell proliferation and migration in breast cancer.
  • Conclusion: The upregulation of circ_0000745 and downregulation of hsa-miR-145-5p may serve as a novel biomarker pattern for the diagnosis and prognosis of breast cancer. These findings indicate that the circRNA-miRNA axis could be a potential therapeutic target in breast cancer treatment, warranting further investigation.
