The CCN family comprises cysteine-rich 61 (CYR61/CCN1), connective tIssue growth factor (CTGF/CCN2), nephroblastoma overexpressed (NOV/CCN3), and Wnt-induced secreted proteins-1 (WISP-1/CCN4), -2 (WISP-2/CCN5) and -3 (WISP-3/CCN6). These proteins stimulate mitosis, adhesion, apoptosis, extracellular matrix production, growth arrest and migration of multiple(More)
Connective tissue growth factor (CTGF) is a member of the recently described CCN gene family which contains CTGF itself, cyr61, nov, elm1, Cop1, and WISP-3. CTGF is transcriptionally activated by several factors although its stimulation by transforming growth factor beta (TGF-beta) has attracted considerable attention. CTGF acts to promote fibroblast(More)
Connective tissue growth factor (CCN2, also known as CTGF) is a matricellular protein that appears to play an important role in hepatic stellate cell (HSC)-mediated fibrogenesis. After signal peptide cleavage, the full-length CCN2 molecule comprises four structural modules (CCN2(1-4)) and is susceptible to proteolysis by HSC yielding isoforms comprising(More)
Connective tissue growth factor (CTGF) and cysteine-rich 61 (CYR61) are prototypical members of the CCN family which also contains nephroblastoma overexpressed (NOV) and Wnt-induced secreted proteins-1, -2 and -3 (WISP-1, -2, -3). These proteins function as extracellular matrix (ECM)-associated signaling molecules that contain structural modules allowing(More)
Uterine growth factors are potential effector molecules in embryo growth signaling pathways. Pig uterine luminal flushings contained a heparin-binding growth factor (HBGF) that required 0.8 M NaCl for elution from heparin columns and was termed HBGF-0.8. This factor, which was heat- and acid-labile and of Mr 10,000 as assessed by gel filtration, stimulated(More)
BACKGROUND Connective tissue growth factor (CCN2) is upregulated in pancreatic fibrosis and desmoplastic pancreatic tumours. CCN2 interacts with integrin alpha5beta1 on pancreatic stellate cells (PSC) in which it stimulates fibrogenesis, adhesion, migration, and proliferation. AIM To determine the structural domain(s) in CCN2 that interact with integrin(More)
BACKGROUND & AIMS Pancreatic stellate cells (PSCs) are proposed to play a key role in the development of pancreatic fibrosis. The aim of this study was to evaluate the production by rat activated PSCs of the fibrogenic protein, connective tissue growth factor (CCN2), and to determine the effects of CCN2 on PSC function. METHODS CCN2 production was(More)
A role for connective tissue growth factor (CTGF) in reproductive function has been suggested from recent studies in the pig. To extend these findings, we have analyzed the immunohistochemical localization of CTGF during the estrous cycle and early pregnancy in mice. During the diestrous and early proestrous stages, CTGF was localized at high levels to both(More)
The CCN family currently comprises six members (CCN1-6) that regulate diverse cell functions, including mitogenesis, adhesion, apoptosis, extracellular matrix (ECM) production, growth arrest, and migration. These properties can result in a multiplicity of effects during development, differentiation, wound healing, and disease states, such as tumorigenesis(More)
