FGFR3 Gene Editing    

Fibroblast growth factor receptor 3 (FGFR3), also known as CD333, is a tyrosine kinase receptor located on the cell membrane and belongs to the FGFR family. The FGFR3 gene is located on human chromosome 4 at p16.3 and contains 19 exons, expressing several slightly different isoforms. FGFR3 protein structure comprises an extracellular structure with 2 or 3 immunoglobulin-like domains, a transmembrane domain and a cytoplasmic tyrosine kinase domain. When the extracellular portion binds with FGF, FGFR3 dimerizes and autophosphorylates and then triggers a downstream signaling cascade that ultimately affects cell growth, migration, angiogenesis, and differentiation.

FGFR3 mutations are often closely related to diseases, including human genetic diseases (Table 1) and cancer. Studies have shown that FGFR3 can regulate ossification and thus affect bone growth, and the over-activation of FGFR3 can lead to achondroplasia, a dominant hereditary disease. In addition, overexpression of FGFR3 provides an oncogenic signal. In bladder cancer, FGFR3 appears post-translational modifications that do not occur in normal cells, suggesting that FGFR3 may be a potential target for the treatment of bladder cancer. FGFR3 inhibitors have been used in cancer treatment in many early clinical trials, such as BGJ398 for urothelial cancer. Studies on the tyrosine kinase signaling pathways mediated by FGFR3 in cell proliferation, drug resistance against anticancer drugs, and other cellular activities have played an important role in promoting bioscience research and new drugs development.
