To investigate the pathophysiological role of fibroblasts in tissue metabolism, we analysed gelatin-degrading enzymes secreted from skin cells in culture. Using a gelatin-zymography method, matrix metalloproteinase (MMP)-2 was constitutively secreted from fibroblasts, whereas both MMP-2 and MMP-9 were secreted from keratinocytes. MMP-9 expression by fibroblasts was induced by the addition of tr...

BACKGROUND To evaluate differential expression of transforming growth factor (TGF-beta1), latent transforming factor-binding proteins (LTBP-1, LTBP-2) and elastin microfibril components (fibrillin-1 and fibrillin-2) in vaginal tissue from women with stress urinary incontinence (SUI). METHODS In this case-control study, vaginal tissue from women in both phases of the menstrual cycle was obtain...

Objective: To investigate effect from total glucosides of paeony on protein expression of nuclear factorκB and transforming growth factor β1 in liver tissue of rats with hepatic fibrosis. Methods: Healthy SD rats were randomly chosen and divided into normal group (group N), model group (group M) and TGP high, medium, low dose treatment group (T1-T3). Except the normal group, all the groups rece...

Transforming growth factor-beta (TGF-beta) activity is controlled at many levels including the conversion of the latent secreted form to its active state. TGF-beta is often released as part of an inactive tripartite complex consisting of TGF-beta, the TGF-beta propeptide, and a molecule of latent TGF-beta binding protein (LTBP). The interaction of TGF-beta and its cleaved propeptide renders the...

Late-onset Alzheimer's disease (LOAD) is the most common form of dementia in the elderly. LOAD has a complex and largely unknown etiology with strong genetic determinants. Genetics of LOAD is known to involve several genetic risk factors among which the Apolipoprotein E (APOE) gene seems to be the major recognized genetic determinant. Recent efforts have been made to identify other genetic fact...

Bronchial smooth muscle cell (BSMC) hyperplasia is a typical feature of airway remodeling and contributes to airway obstruction and hyperresponsiveness in asthma. Fibroblast growth factor 2 (FGF-2) and transforming growth factor beta1 (TGF-beta1) are sequentially upregulated in asthmatic airways after allergic challenge. Whereas FGF-2 induces BSMC proliferation, the mitogenic effect of TGF-beta...

After injury to the CNS, extracellular matrix molecules such as tenascin are upregulated around the injury site and may be involved in inhibition of axon growth. In the present study, astrocytes were investigated to determine which cell types, growth factors, or cytokines are responsible for the injury-induced regulation of tenascin. The addition of activated macrophage- or microglial-condition...

Transforming growth factor (TGF)-beta1 is rapidly activated after ionizing radiation, but its specific role in cellular responses to DNA damage is not known. Here we use Tgfbeta1 knockout mice to show that radiation-induced apoptotic response is TGF-beta1 dependent in the mammary epithelium, and that both apoptosis and inhibition of proliferation in response to DNA damage decrease as a function...

introduction: transforming growth factor-beta 1 (tgf-β1) is a pleiotropic cytokine with potent anti-inflammatory property, which has been considered as an essential risk factor in the inflammatory process of ischemic stroke (is), by involving in the pathophysiological progression of hypertension, atherosclerosis, and lipid metabolisms. -509c/t tgf-β1 gene polymorphism has been found to be assoc...
