CTGF is a matricellular protein that belongs to the CCN (Cyr61/CTGF/Nov) family. It plays a pivotal role in diverse biological processes, including cell adhesion, migration, proliferation, and differentiation. CTGF is also involved in wound healing and fibrosis. In cancer, CTGF’s function is multifaceted, affecting tumor growth, angiogenesis, and the remodeling of the tumor microenvironment.
CTGF is overexpressed in several cancer types, such as pancreatic, breast, and prostate cancers. In these contexts, higher levels of CTGF have been associated with enhanced tumor growth, angiogenesis, and metastasis.
Elevated CTGF expression often correlates with adverse clinical features.
CCN2 - Cellular Communication Network Factor 2 / Connective Tissue Growth Factor
Abbreviation: CCN2, CTGF
Type: Matricellular protein / extracellular signaling protein
Function: CCN2 is a secreted matricellular protein that regulates cell adhesion, migration, proliferation, extracellular-matrix remodeling, fibrosis, angiogenesis, and interactions between tumor cells and stromal cells. It is strongly influenced by signaling pathways including TGF-β, YAP/TAZ, integrins, and growth-factor signaling.
Cancer: ↑ Frequently increased in tumors and tumor-associated stroma. Elevated CCN2 can promote fibrosis, cancer-associated fibroblast activation, extracellular-matrix deposition, tumor-cell survival, invasion, angiogenesis, metastatic niche formation, and resistance to therapy. Its effects are context-dependent, but increased CCN2 is predominantly associated with tumor progression in many solid cancers.
