Background
Periostin is a 90-kDa secreted matricellular protein that consists of a typical signal peptide, an EMI domain, four tandem fasciclin-1 (FAS-1) domains implicated in cell adhesion and protein–protein interactions, and a C-terminal splice variant-rich domain that can generate six isoforms; it is predominantly expressed in collagen-rich connective tissues such as periodontal ligament, periosteum, heart valves, skin, and fibrotic lesions, where it is rapidly induced by TGF-β, IL-4/IL-13, mechanical stress or hypoxia and then deposited into the extracellular matrix via integrin-mediated binding to αvβ3, αvβ5 or α6β4 receptors on fibroblasts, thereby promoting collagen fibrillogenesis, cross-linking and tissue remodeling during embryonic development, wound healing, bone fracture repair, cardiac remodeling after myocardial infarction, and pathological fibrosis in asthma, atopic dermatitis, liver cirrhosis and various solid tumors, while also activating PI3K/Akt, FAK/Src, ERK and YAP/TAZ signaling pathways that enhance epithelial–mesenchymal transition, angiogenesis, cancer cell invasion, metastatic niche formation and chemoresistance, making it a valuable biomarker for disease progression and a potential therapeutic target for fibrosis and cancer.
