Role of miRNA‑145‑5p in cancer (Review).

MicroRNA‑145‑5p (miRNA‑145‑5p) is a short non‑coding RNA located at chromosome 5q33.1, which has gained significant attention in several aspects of cellular regulation and biological functions. In malignant tumours, miRNA‑145‑5p may function as either a tumour suppressor or an oncogene, affecting tumour progression by targeting downstream genes or modulating their expression through upstream regulators. However, the full extent of miRNA‑145‑5p's role in cancer has remained to be determined. This review provides an overview of the role of miRNA‑145‑5p in cancer, investigates its potential as a biomarker for diagnosis, prognosis and treatment response, and evaluates its influence on cancer chemotherapy and radiotherapy. Finally, current strategies for systemic delivery of miRNA‑145‑5p in cancer therapies are summarized.
