bronchial asthma is the common chronic inflammatory disease and is characterized by chronic airway inflammation, airway remodeling, and airway hyperreactivity (ahr). aim of this study was to investigate the effects of mitochondrial atp-sensitive potassium channels (mitokatp) on the proliferation and secretion of human airway smooth muscle cells (hasmcs). hasmcs were treated with the serum from ...

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 ...

Transforming growth factor β1 (TGF-β1) is a cytokine affecting cell proliferation and development, which also has an immunomodulatory activity. Correlations between polymorphisms of the TGF-β1 gene and clinical parameters of inflammatory bowel disease (IBD) were reported previously in adults. Here, we tested whether such correlations occur in pediatric patients suffering from IBD. One hundred a...

BACKGROUND CCN2 acts as an anabolic growth factor to regulate osteoblast differentiation and function. CCN2 is induced by TGF-β1 and acts as a mediator of TGF-β1 induced matrix production in osteoblasts and Src is required for CCN2 induction by TGF-β1; however, the molecular mechanisms that control CCN2 induction in osteoblasts are poorly understood. AFAP1 binds activated forms of Src and can d...

Pulmonary fibrosis is a fatal progressive disease with no effective therapy. Transforming growth factor (TGF)-β1 has long been regarded as a central mediator of tissue fibrosis that involves multiple organs including skin, liver, kidney, and lung. Thus, TGF-β1 and its signaling pathways have been attractive therapeutic targets for the development of antifibrotic drugs. However, the essential bi...

Circulating platelets contain high concentrations of TGF-β1 in their α-granules and release it on platelet adhesion/activation. We hypothesized that uncontrolled in vitro release of platelet TGF-β1 may confound measurement of plasma TGF-β1 in mice and that in vivo release and activation may contribute to cardiac pathology in response to constriction of the transverse aorta, which produces both ...

OBJECTIVE To investigate the expression and correlation of transforming growth factor-β1 (TGF-β1) and fibroblast growth factor receptor 4 (FGFR4) in human hepatocellular carcinoma (HCC) and the relationship with clinicopathological features and prognosis. MATERIALS AND METHODS The expression of TGF-β1 and FGFR4 in 126 HCC samples was detected immunohistochemically. Combined with clinical post...

Propofol anesthesia and sedation are known to downregulate the functions of many hematopoietic cells, such as macrophages and neutrophils, in vivo. However, the effects of propofol on secretion of the regulatory cytokine transforming growth factor β1 (TGF-β1) in vivo are unknown. In this study, the effects of propofol on TGF-β1 expression in human peripheral blood mononuclear cells, umbilical v...

INTRODUCTION While the anti-resorptive effects of the bisphosphonates (BPs) are well documented, many questions remain about their mechanisms of action, particularly following long-term use. This study evaluated the effects of alendronate (Ale) treatment on TGF-β1 signaling in mesenchymal stem cells (MSCs) and osteocytes, and the relationship between prolonged alendronate treatment on systemic ...
