Vascular endothelial growth factor (VEGF) is a mediator of airway inflammation and remodelling in asthma. Transforming growth factor (TGF)-beta(1) plays pivotal roles in diverse biological processes, including tissue remodelling and repair in a number of chronic lung diseases. However, there are few studies elucidating the interactions between VEGF and TGF-beta(1) in allergic airway disease. A ...

Transforming growth factor beta (TGF-beta) is released from cells in a latent form consisting of the mature growth factor associated with an aminoterminal propeptide and latent TGF-beta binding protein (LTBP). The endogenous activation of latent TGF-beta has been described in co-cultures of endothelial and smooth muscle cells. However, the mechanism of this activation remains unknown. Antibodie...

introduction: natural biomaterials and growth factors are key factors in tissue engineering. the objective of the present study was to evaluate transforming growth factor beta 1 (tgf-β1) and curcumin on proliferation and differentiation of nasal-derived chondrocyte seeded on the fibrin glue scaffold. methods: chondrocytes were isolated from nasal samples. nasal-derived chondrocytes were seeded ...

High molecular weight transforming growth factor-beta (TGF beta) is a physiologically active TGF secreted by nodular sclerosing Reed-Sternberg cells. Five monoclonal murine antibodies were prepared that distinguished Hodgkin's TGF beta from platelet-derived TGF beta using an enzyme-linked immunosorbent assay, neutralization of biologic activity, and Western blotting. These monoclonal antibodies...

The transforming growth factor-beta (TGF-beta) pathway plays dual roles in cancer, inhibiting epithelial cell growth under normal physiologic conditions, but promoting invasion and metastasis once growth inhibitory responses are lost. Two recent papers show that TGF-beta receptor III is the most common TGF-beta pathway component downregulated in prostate cancer. Here, we discuss the implication...

Background: To our knowledge, there is a hypothesis regardingthe association of vitiligo with other autoimmune disorders.Organ-specific autoantibodies are found more frequently in theserum of vitiligo patients. Recent studies have demonstratedthe role of alterations in serum transforming growth factor-beta(TGF-beta) released from regulatory T cells in the pathogenesisof depigmentation observed ...

The distribution of transforming growth factor (TGF)-alpha and TGF-beta 1 mRNA containing cells in adult mouse brain was examined using in situ hybridization histochemistry. There were no detectable TGF-beta 1 mRNA-containing cells found in the brain. TGF-alpha mRNA was localized to cell bodies of the caudate nucleus, dentate gyrus, anterior olfactory nuclei, and a laminar distribution of mitra...

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&n...

Alteration in the expression of growth factors is widely accepted as being one of several critical defects in the generation of the malignant cell. In the present study, 19 human metastatic melanoma cell lines were compared to 14 normal human foreskin melanocyte cell lines for the production of RNA transcripts specific for 11 different growth factors. Using the extremely sensitive technique of ...

Transforming growth factor-beta (TGF-beta) is a multifunctional polypeptide that regulates cell growth, differentiation, and extracellular matrix formation. Studies on genetically engineered animal models have demonstrated that TGF-beta-mediated signaling pathway plays a critical role in both normal development and tumorigenesis of the breast. In pathogenesis of breast cancer, the role of TGF-b...
