摘 要：Non-enzymatic chitinase-3 like-protein-1(CHI3L1)belongs to glycoside hydrolase family 18.It binds to chitin,heparin,and hyaluronic acid,and is regulated by extracellular matrix changes,cytokines,growth factors,drugs,and stress.CHI3L1 is synthesized and secreted by a multitude of cells including macrophages,neutrophils,synoviocytes,chondrocytes,fibroblast-like cells,smooth muscle cells,and tumor cells.It plays a major role in tissue injury,inflammation,tissue repair,and remodeling responses.CHI3L1 has been strongly associated with diseases including asthma,arthritis,sepsis,diabetes,liver fibrosis,and coronary artery disease.Moreover,following its initial identification in the culture supernatant of the MG63 osteosarcoma cell line,CHI3L1 has been shown to be overexpressed in a wealth of both human cancers and animal tumor models.To date,interleukin-13 receptor subunit alpha-2,transmembrane protein 219,galectin-3,chemo-attractant receptor-homologous 2,and CD44 have been identified as CHI3L1 receptors.CHI3L1 signaling plays a critical role in cancer cell growth,proliferation,invasion,metastasis,angiogenesis,activation of tumor-associated macrophages,and Th2 polarization of CD4+T cells.Interestingly,CHI3L1-based targeted therapy has been increasingly applied to the treatment of tumors including glioma and colon cancer as well as rheumatoid arthritis.This review summarizes the potential roles and mechanisms of CHI3L1 in oncogenesis and disease pathogenesis,then posits investigational strategies for targeted therapies.
