Transforming growth factor-β (TGF-β) stimulates α1(I) collagen mRNA synthesis in human lung fibroblasts through a mechanism that is partially sensitive to cycloheximide and that may involve synthesis of connective tissue growth factor (CTGF). Northern blot analyses indicate that TGF-β stimulates time- and dose-dependent increases in CTGF mRNA. In TGF-β-stimulated fibroblasts, maximal levels of ...

BACKGROUND Tumor invasion and metastasis cause most deaths in cancer patients. Connective tissue growth factor (CTGF), a secreted protein that binds to integrins, modulates the invasive behavior of certain human cancer cells, but few mechanistic details are known. We investigated the roles of CTGF and collapsin response mediator protein 1 (CRMP-1) in metastasis and invasion of human lung adenoc...

PURPOSE Conjunctival fibrosis due to excessive accumulation of collagens is an important histologic feature in ocular cicatricial pemphigoid (OCP). Studies have suggested a role of transforming growth factor (TGF)-beta1 in conjunctival fibrosis in patients with OCP. Connective tissue growth factor (CTGF) is an important downstream mediator of TGF-beta1-induced collagen synthesis. CTGF usually a...

Matrix accumulation in the renal tubulointerstitium is predictive of a progressive decline in renal function. Transforming growth factor-beta(1) (TGF-beta(1)) and, more recently, connective tissue growth factor (CTGF) are recognized to play key roles in mediating the fibrogenic response, independently of the primary renal insult. Further definition of the independent and interrelated effects of...

Perspectives on whether the functions of MAS, a G protein-coupled receptor, are beneficial or deleterious in the heart remain controversial. MAS gene knockout reduces coronary vasodilatation leading to ischemic injury. G protein signaling activated by MAS has been implicated in progression of adaptive cardiac hypertrophy to heart failure and fibrosis. In the present study, we observed increased...

Ovarian low-grade serous carcinoma (LGSC) is a rare disease and is now considered to be a distinct entity from high-grade serous carcinoma (HGSC), which is the most common and malignant form of epithelial ovarian cancer. Connective tissue growth factor (CTGF) is a secreted matricellular protein that has been shown to modulate many biological functions by interacting with multiple molecules in t...

Connective tissue growth factor (CTGF) level is elevated in eyes with proliferative vitreoretinal diseases, such as proliferative diabetic retinopathy and proliferative vitreoretinopathy (PVR), as we previously reported, but its functional characteristics on vitreoretinal cells are yet to be clarified. In this study, we demonstrated a growth-promoting effect of CTGF on cultured hyalocytes and b...

Connective tissue growth factor (CTGF) is abundantly expressed in the vascular smooth muscle cells (VSMC) of atherosclerotic lesions but not in normal vessels. CTGF is able to promote VSMC proliferation and migration and influences the composition of extracellular matrix. The mechanisms for controlling these events remain unclear. We studied the effects of CTGF on matrix metalloproteinases (MMP...

CCN2/CTGF (CCN family 2/connective tissue growth factor) is a multi-cellular protein with a broad range of activities. It modulates many cellular functions, including proliferation, migration, adhesion and extracellular matrix production, and it is thus involved in many biological and pathological processes. In particular, CCN2/CTGF is essential for normal skeletal development. To identify CCN2...

Connective tissue growth factor [CTGF]/CCN2 is a prototypic member of the CCN family of regulatory proteins. CTGF expression is up-regulated in a number of fibrotic diseases, including diabetic nephropathy, where it is believed to act as a downstream mediator of TGF-beta function; however, the exact mechanisms whereby CTGF mediates its effects remain unclear. Here, we describe the role of CTGF ...
