Integrative Regulatory Networks of MicroRNA-483: Unveiling Its Systematic Role in Human Diseases and Clinical Implications

MicroRNA-483 regulates multiple human disease categories, spanning oncology, cardiopulmonary, metabolic, immune, neurological, and musculoskeletal pathologies. We integrate experimentally validated interactions from 146 studies to construct a comprehensive regulatory network, encompassing transcription factors, long non-coding RNAs, circular RNAs, and messenger RNA targets. Our analysis reveals that miR-483 promotes tumorigenesis by suppressing tumor-suppressive checkpoints, yet it protects cardiopulmonary, metabolic, and neurological tissues from pathological injury. This functional duality arises from tissue-specific modulation of shared signaling pathways, particularly TGF-β and MAPK cascades, which function as the core hubs driving its context-dependent activity across six disease categories. By mapping miR-483 regulatory circuits across multiple diseases, we define the molecular determinants of its context-dependent activity. These findings establish miR-483 as both a diagnostic biomarker and a therapeutic target whose function is dictated by cellular context.
