BACKGROUND
Cyr61, also known as CCN1, is a 40 45
kDa matricellular glycoprotein that plays an important role in cellular adhesion and migration (1). Cyr61 consists of an
IGFBP domain, a VWF type C domain, a TSP type I domain, and a cysteine knot domain (2). Mature human Cyr61 shares 93% amino acid sequence identity with
mouse and rat Cyr61. It is widely expressed during development and in adult tissues (2, 3). Cyr61 associates with the extracellular matrix (ECM) and with many cell
surface molecules including Integrins αVβ3, αVβ5, αMβ2, and α6β1, Syndecan4,
and heparan sulfate proteoglycans (1, 3). Cyr61 mediates the adhesion and migration
of multiple cell types and also promotes vascular endothelial cell tubule formation (4 6).
Plasmin cleavage of ECMbound
Cyr61 releases a 28 kDa Nterminal
fragment which retains the ability to promote endothelial cell migration (7). Cyr61 exhibits both tumorigenic and tumor suppressor properties. It is up-regulated and
promotes tumorigenesis, angiogenesis, and metastasis in breast, renal, gastric, squamous cell, and colorectal carcinomas as well as in glioma (8 - 12). In contrast,
when down-regulated, it suppresses tumor growth in endometrial, hepatic, and nonsmall
cell lung cancers (8, 13, 14). Cyr61 is also up-regulated in injured skin and
bone where it induces the expression of growth factors, cytokines, proteases, and integrins involved in wound repair (15, 16).
