Abstract

Chemotherapy-induced peripheral neuropathy (CIPN) is a significant adverse effect of cancer therapies that profoundly disrupts the quality of life for patients. CIPN is characterized by sensory symptoms such as pain, tingling, and numbness, typically distributed in a “glove and stocking” pattern. Its underlying mechanisms remain incompletely understood, involving complex processes such as heightened neuronal excitability, alterations in ion channel function, neuroinflammation, and glial cell activation. MicroRNAs (miRNAs), small non-coding RNA molecules, play a pivotal role in regulating these processes by modulating gene expression and cellular functions. Emerging evidence suggests that specific miRNAs, including miR-30b-5p, miR-155, miR-124, and miR-21, are involved in regulating pathways that contribute to CIPN-related pain. These miRNAs influence the function of ion channels, glial cell activation, and neuroinflammation. MiRNAs hold significant promise as biomarkers for the early detection of CIPN. This review comprehensively examines the current understanding of miRNA-mediated mechanisms contributing to CIPN development. Key miRNAs implicated in modulating these pathways are discussed in detail, including their potential as diagnostic biomarkers and therapeutic targets. By integrating molecular insights with translational approaches, this review provides a framework for future research and clinical applications targeting miRNA pathways to mitigate CIPN and improve outcomes for cancer patients undergoing chemotherapy. © 2025 Informa UK Limited, trading as Taylor & Francis Group.
