Description

Connective Tissue Growth Factor (CTGF) is a member of the CCN (CYR61/CTGF/NOV) family of secreted proteins that share a multimodular organization. Each CCN member contains an IGF­binding protein domain, a von Willebrand factor type C domain, a thrombospondin type I domain, and a cysteine knot domain. The multimodular CTGF binds multiple ligands and shows effects in development, differentiation, and tumorigenesis. CTGF is a mitogen that is secreted by vascular endothelial cells. It plays a role in chondrocyte proliferation and differentiation, cell adhesion in many cell types, and is related to platelet-derived growth factor. The C­terminal cysteine knot motif contains the heparin and low-density lipoprotein receptor (LDLR) binding sites that contributes to the adhesive and mitogenic properties of CTGF.  Certain polymorphisms in this gene have been linked with a higher incidence of systemic sclerosis. CTGF is the central mediator of tissue remodeling and fibrosis.  It is implicated in tumor progression and metastasis.  It promotes epithelial to mesenchymal transition (EMT), a process whereby normal epithelial cells become migratory, matrix-producing fibroblasts important for invasion and metastasis.  Elevated CTGF levels are found in desmoplastic cancer where it supports the formation of the extensive fibrous connective tissue (desmoplasia) around cancer.  Blockade of the expression or activity of CTGF reduces tumor growth and metastasis in serveral cancer animal model.
