During pregnancy, maternal β-cells undergo compensatory changes, including increased β-cell mass and enhanced glucose-stimulated insulin secretion. Failure of these adaptations to occur results in gestational diabetes mellitus. The secreted protein connective tissue growth factor (CTGF) is critical for normal β-cell development and promotes regeneration after partial β-cell ablation. During emb...

In skin, connective tissue growth factor (CTGF/CCN2) is induced during tissue repair. However, what the exact cell types are that express CTGF in normal and wounded skin remain controversial. In this report, we use transgenic knock-in mice in which the Pacific jellyfish Aequorea victoria enhanced green fluorescent protein (E-GFP) gene has been inserted between the endogenous CTGF promoter and g...

Tubular epithelial cells secrete connective tissue growth factor (CTGF, CCN2), which contributes to tubulointerstitial fibrosis. However, the molecular regulation of CTGF in human primary tubular epithelial cells (hPTECs) is not well defined. Therefore, CTGF expression was characterized in hPTECs isolated from healthy parts of tumor nephrectomies, with special emphasis on the regulation by tran...

Connective tissue growth factor (CTGF) is a M(r)38,000 cysteine-rich peptide, the synthesis and secretion of which are selectively induced by transforming growth factor beta (TGF-beta). The relationship of CTGF to TGF-beta action on fibroblastic cells is not well understood. TGF-beta has the unique ability to stimulate the growth of normal fibroblasts in soft agar, a property of transformed cel...

Increasing evidence shows that DNA methylation is involved in the development and progression of diabetes mellitus (DM) and its complications. Previous studies conducted by our group have indicated that high glucose levels may induce the demethylation process of the connective tissue growth factor (CTGF) gene promoter and increase the expression of CTGF in human glomerular mesangial cells. Base...

BACKGROUND Prokineticin-1 (PROK1) and connective tissue growth factor (CTGF) are expressed in human endometrium and first-trimester decidua and have individually been proposed to have roles in implantation and placentation. We have recently demonstrated that CTGF may be a target gene for PROK1 in gene array analysis of a prokineticin receptor-1 stably transfected Ishikawa endometrial epithelial...

OBJECTIVE Complications due to fibrosis development are common in patients with well-differentiated endocrine carcinomas in the small intestine (ileal carcinoids). Connective tissue growth factor (CTGF) expression in ileal carcinoids may be related to this fibrosis development. This study aimed to examine CTGF expression in relation to local myofibroblast differentiation in a large series of il...

Connective tissue growth factor (CTGF) is one of the candidate factors mediating downstream events of transforming growth factor-beta (TGF-beta), but its role in fibrogenic properties of TGF-beta and in tubulointerstitial fibrosis has not yet been clarified. Using unilateral ureteral obstruction (UUO) in rats, we analyzed gene expression of TGF-beta1, CTGF, and fibronectin. We further investiga...

Connective tissue growth factor (CTGF/CCN2) is thought to play a role in normal wound repair and bone remodeling, but also promotes fibrosis in several disease processes including diabetic nephropathy, sclerodoma and pancreatitis. A contribution to desmoplasia associated with pancreatic cancer progression has also been proposed. CTGF is induced by TGFbeta in diverse cell types, but TGFbeta rece...

Aims: To determine the localisation and distribution of connective tissue growth factor (CCN2; CTGF) and transforming growth factor β type 1 (TGF-β1) in uterine tissues from cycling and early pregnant pigs. Methods: In situ hybridisation and immunohistochemistry were used to localise CCN2 (CTGF) or TGF-β1 in uteri obtained from gilts on days 0, 5, 10, 12, 15, and 18 of the oestrous cycle or day...
