Transforming growth factorbeta1 (TGF-beta1) is the main modulator of the healing process after tissue injury. In the kidney, if TGF-beta1 release is not switched off, extracellular matrix components (ECM) are accumulated and tissue fibrosis occurs. Urinary TGF-beta1 levels reflect its renal production and it has been determined in various types of glomerular disease. In this review, a critical ...
Transforming growth factor beta is a potent immunomodulator with both pro- and antiinflammatory activities. Based on its immunosuppressive actions, exogenous TGF-beta has been shown to inhibit autoimmune and chronic inflammatory diseases. To further explore the potential therapeutic role of TGF-beta, we administered a plasmid DNA encoding human TGF-beta1 intramuscularly to rats with streptococc...
The socioeconomic implications of trypanosomosis in sub-Saharan Africa and the limitations of its current control regimes have stimulated research into alternative control methods. Considering the pro- and anti-inflammatory properties of transforming growth factor beta1 (TGF-beta1) and its potential to enhance immunity against protozoan parasites, we examined the effects of intraperitoneally de...
We have previously shown that abnormal iron metabolism might be one underlying mechanism of the renal damage observed in the angiotensin II-infused rat. Transforming growth factor-beta1 (TGF-beta1) is known to play a crucial role in the development of renal damage induced by activation of the renin-angiotensin-aldosterone system. The purpose of the present study was to examine the effects of an...
Alcohol abuse markedly increases the risk of sepsis-mediated acute lung injury. In a rat model, ethanol ingestion alone (in the absence of any other stress) causes pulmonary glutathione depletion, increased expression of transforming growth factor-beta1 (TGF-beta1), and alveolar epithelial barrier dysfunction, even though the lung appears grossly normal. However, during endotoxemia, ethanol-fed...
BACKGROUND AND OBJECTIVE Research has confirmed that transforming growth factor-beta1 (TGF-beta1) is one of the cytokines related to radiation pneumonitis. But the level of TGF-beta1 in serum needed to predict radiation pneumonitis is still not clear. This study assessed the value of TGF-beta1 in both serum and induced sputum in predicting radiation pneumonitis, providing a reference for the ra...
Adipose tissue-derived mesenchymal stem cells (AT-MSCs) in combination with bone morphogenetic protein-2 (BMP-2) or transforming growth factor-beta1 (TGF-beta1) are under evaluation for bone tissue engineering. Posttranslational modification of type I collagen is essential for functional bone tissue with adequate physical and mechanical properties. We investigated whether BMP-2 (10-100 ng/mL) a...
Differential effects of EGF and TGF-beta1 on fibroblast activity in fibrin-based tissue equivalents.
Transforming growth factor-beta1 (TGF-beta1) is commonly used to promote matrix production for engineered tissues in vitro, yet it also enhances fibroblast contractility. For applications where contraction is undesirable, we hypothesized that epidermal growth factor (EGF) would yield equivalent mechanical properties without enhancing contractility. In this study, the response of human dermal fi...
There is increasing evidence that epithelial to mesenchymal transition (EMT) is involved in cancer progression. Because local invasion and metastasis occurs early in the pathogenesis of esophageal adenocarcinoma, we hypothesized that EMT may be important in this disease. Using immunohistochemistry in a well-characterized set of adenocarcinoma tissues, we showed down-regulation of epithelial mar...
Hepatocyte growth factor (HGF) receptor is a transmembrane receptor tyrosine kinase encoded by the c-met protooncogene. In this study, we demonstrated that c-met expression was upregulated in the kidney after obstructive injury in mice. Because the pattern of c-met induction was closely correlated with transforming growth factor-beta1 (TGF-beta1) expression in vivo, we further investigated the ...
