Abstract

Fibroblast growth factor 12 (FGF12), a member of the intracellular fibroblast growth factor homologous factor (iFGF) subfamily, has been widely studied for its role in the modulation of voltage-gated ion channels. However, recent studies suggest that FGF12 possesses various cellular functions beyond ion channel regulation, particularly in cancer progression. Accumulating evidence indicates that the upregulation of FGF12 is associated with tumor survival, therapeutic resistance, and poor prognosis through signaling pathways independent of its canonical ion channel interactions. This review summarizes the current understanding of FGF12’s non-canonical functions, highlights its emerging roles in cellular regulation, and discusses its potential mechanism in oncogenic progression. Understanding these novel functions may provide a new aspect for therapeutic targeting of FGF12 in malignancies.
