PURPOSE Connective tissue growth factor (CTGF) appears to play a significant role in mediating fibrosis in several tissues. To gain further understanding of the role of CTGF in the scar formation that occurs after glaucoma filtering surgery (GFS), experiments were performed in a rabbit model. METHODS . Three experiments were performed: (1) CTGF and transforming growth factor (TGF)-beta expres...

OBJECTIVE Connective tissue growth factor (CTGF) is a major fibrogenic factor. Increased retinal CTGF levels have been implicated to play a role in diabetic retinopathy. SERPINA3K is a serine proteinase inhibitor, and its levels were decreased in retinas with diabetic retinopathy. The purpose of this study was to investigate the role of SERPINA3K in the regulation of CTGF and fibrogenesis and i...

Connective tissue growth factor (CTGF) plays an important role in fibrosis by modulating cell migration and cell growth but may also modify tumor growth and metastasis. Because CTGF is overexpressed in pancreatic ductal adenocarcinoma, we investigated the in vitro effects of CTGF on the proliferation and invasiveness of PANC-1 pancreatic cancer cells and examined the consequences of its in vivo...

In vitro experiments showed that the connecting tubule (CNT) sends a signal that dilates the afferent arteriole (Af-Art) when Na(+) reabsorption in the CNT lumen increases. We call this process CNT glomerular feedback (CTGF) to differentiate it from tubuloglomerular feedback (TGF), which is a cross talk between the macula densa (MD) and the Af-Art. In TGF, the MD signals the Af-Art to constrict...

Transforming growth factor-β1 (TGF-β1) plays an important role in the pathogenesis and progression of chronic kidney disease. Connective tissue growth factor (CTGF) is a critical fibrogenic mediator of TGF-β1. Mammalian sirtuin 1 (Sirt1) is reported to attenuate renal fibrosis by inhibiting the TGF-β1 pathway. This study was designed to detect whether the delivery of CTGF siRNA in vivo directly...

Cardiac transplantation is an effective treatment for multiple types of heart failure refractive to therapy. Although immunosuppressive therapeutics have increased survival rates within the first year posttransplant, chronic rejection (CR) remains a significant barrier to long-term graft survival. Indicators of CR include patchy interstitial fibrosis, vascular occlusion and progressive loss of ...

Connective tissue growth factor (CTGF) has a major role in development of fibrosis and in the wound-healing process. Microarray analysis of 44 classical Hodgkin lymphoma (cHL) samples showed higher CTGF messenger RNA expression in the nodular sclerosis (NS) than in the mixed cellularity (MC) subtype. When analyzed by immunohistochemical analysis, Hodgkin-Reed-Sternberg (H-RS) cells and macropha...

PURPOSE Connective Tissue Growth Factor (CTGF) is an inducible secretory protein known to regulate proliferation and extracellular matrix production in various cell types. We hypothesize that CTGF plays a critical role in the physiological regulation of aqueous humor outflow through the trabecular meshwork (TM) by influencing extracellular matrix synthesis and organization. METHODS To determi...

Connective tissue growth factor (CTGF) participates in diverse fibrotic processes including glomerulosclerosis. The adenylyl cyclase agonist forskolin inhibits CTGF expression in mesangial cells by unclear mechanisms. We recently reported that the histone H3K79 methyltransferase disruptor of telomeric silencing-1 (Dot1) suppresses CTGF gene expression in collecting duct cells (J Clin Invest 117...

PURPOSE To investigate the role of connective tissue growth factor (CTGF) in the pathogenesis of proliferative vitreoretinopathy (PVR). METHODS Expression of CTGF was evaluated immunohistochemically in human PVR membranes, and the accumulation of CTGF in the vitreous was evaluated by ELISA. The effects of CTGF on type I collagen mRNA and protein expression in RPE were assayed by real-time PCR...
