The Fragile X Mental Retardation 1 (FMR1) gene is well-known for its role in Fragile X syndrome, a neurodevelopmental disorder, but emerging evidence suggests its involvement in regulating cellular metabolism, with implications for cancer biology. FMR1 encodes the Fragile X mental retardation protein (FMRP), an RNA-binding protein that controls various cellular processes, including translation, synaptic plasticity, and RNA metabolism. Recent studies have uncovered novel links between FMR1, metabolic regulation, and tumorigenesis. This review discusses the role of FMR1 in cellular metabolism and its potential involvement in cancer, focusing on glycolysis, mitochondrial metabolism, lipid metabolism, immune cell metabolism, and tumor immune evasion, and as a potential target to enhance immunotherapy, and highlights future research directions to elucidate its mechanistic roles in cancer.
