%X MicroRNAs (miRNAs) have emerged as crucial regulators of gene expression, playing pivotal roles in various biological processes, including cancer development and progression. Among them, miR-125b has garnered significant attention due to its multifaceted functional roles in human hepatocellular carcinoma (HCC). Extensive research has revealed that miR-125b plays a dual role in HCC, acting as both a tumor suppressor and an oncogene depending on the context. As a tumor suppressor, miR-125b exerts its inhibitory effects on HCC by targeting key oncogenic pathways and genes involved in cell proliferation, migration, invasion, and angiogenesis. Its downregulation in HCC is frequently observed and correlates with aggressive tumor characteristics and poor prognosis. Conversely, miR-125b can also function as an oncogene in specific HCC subtypes or under certain conditions. It has been shown to promote HCC growth, metastasis, and therapeutic resistance by targeting tumor suppressor genes, modulating the epithelial-mesenchymal transition (EMT) process, and enhancing cancer stem cell-like properties. The upregulation of miR-125b in HCC has been associated with advanced disease stages and unfavorable clinical outcomes. Furthermore, the dysregulation of miR-125b expression in HCC is influenced by a complex network of regulatory mechanisms. Understanding these regulatory mechanisms is crucial for deciphering the precise functional roles of miR-125b in HCC and exploring its potential as a diagnostic biomarker or therapeutic target. In the current review study, we comprehensively elucidated the diverse functional roles of miR-125b in HCC, providing a comprehensive overview of its regulatory mechanisms and impact on key cellular processes involved in HCC progression.
