Abstract
MicroRNAs (miRNAs) are small non-coding RNAs that serve key roles in cell proliferation, migration, invasion and apoptosis by regulating gene expression.In malignant tumors, miRNA-122 serves either as a tumor suppressor or oncogene, influencing tumor progression via downstream gene targeting.However, the precise role of miRNA-122 in cancer remains unclear.miRNA-122 is a potential biomarker and modulator of radiotherapy and chemotherapy.The present review aimed to summarize the roles of miRNA-122 in cancer, its potential as a biomarker for diagnosis and prognosis and its implications in cancer therapy, including radiotherapy and chemotherapy, alongside strategies for systemic delivery.
