RNA-Binding Motif Protein 3 as a Therapeutic and Prognostic Target for Drug Discovery

This comprehensive literature review delves into the multifaceted roles of RNA-binding motif protein 3 (RBM3) in cellular processes, disease pathogenesis, and therapeutic potential. RBM3 has been implicated in shaping cell morphology, synaptic protection in neurodegenerative conditions, and regulating gene expression through binding to specific RNA sequences. In cancer, RBM3 exhibits contrasting effects, influencing cell proliferation, tumorigenic potential, and RNA splicing. Clinical studies suggest RBM3 as a predictive biomarker in chemotherapy response for muscle-invasive bladder cancer. Despite promising therapeutic implications in neuroprotection and cancer, challenges persist in understanding the regulatory mechanisms and clinical behavior of RBM3. Further research is warranted to elucidate the molecular mechanisms underlying RBM3's diverse functions and its significance as a potential target for personalized medicine in cancer therapy. This review underscores the pivotal role of RBPs, particularly RBM3, in disease progression and highlights the need for continued investigation to harness their therapeutic potential effectively. This review evaluates evidence available through December 2025, with particular emphasis on studies published between 2010 and 2025.
