OBJECTIVE Calcific aortic valve disease is a progressive condition that shares some common pathogenic features with atherosclerosis. Transforming growth factor-β1 is a recognized mediator of atherosclerosis and is expressed in aortic valve lesions. Transforming growth factorβ1 stimulates glycosaminoglycan elongation of proteoglycans that is associated with increased lipid binding. We investigat...
Megakaryocytes release platelets into the bloodstream by elongating proplatelets. In this study, we showed that human megakaryocytes constitutively release Transforming Growth Factor β1 and express its receptors. Importantly, Transforming Growth Factor β1 downstream signaling, through SMAD2/3 phosphorylation, was shown to be active in megakaryocytes extending proplatelets, indicating a type of ...
BACKGROUND Familial sick sinus syndrome is associated with gene mutations and dysfunction of ion channels. In contrast, degenerative fibrosis of the sinus node tissue plays an important role in the pathogenesis of acquired sick sinus syndrome. There is a close relationship between transforming growth factor-β1 mediated cardiac fibrosis and acquired arrhythmia. It is of interest to examine wheth...
Transforming growth factor-β1 is considered a key contributor to the progression of breast cancer. MicroRNAs are important factors in the development and progression of many malignancies. In the present study, upon studies of breast cancer cell lines and tissues, we showed that microRNA -196a-3p is decreased by transforming growth factor-β1 in breast cancer cells and associated with breast canc...
OBJECTIVES The biological functions of transforming growth factor-β signaling that involves Smad proteins have not been previously investigated with respect to coronary artery bypass grafts. The aim of the present study was to observe the immunostaining of proteins that are related to this signaling pathway. METHODS Fifteen remnants of coronary artery bypass grafts, including nine saphenous v...
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 ...
BACKGROUND Recent studies have demonstrated that transforming growth factor-β1 (TGF-β1) and connective transforming growth factor (CTGF) are associated with the pathophysiology of liver fibrosis. We isolated protocatechuic aldehyde, the major degradation of phenolic acids. OBJECTIVE This study was carried out to investigate the potential antifibrotic effect of Protocatechuic aldehyde (PA) on ...
OBJECTIVES: Henoch-Schönlein purpura nephritis and immunoglobulin A nephropathy are two diseases with similar clinical presentations but very different prognoses. Transforming growth factor β1 and monocyte chemoattractant protein-1 have been associated with the development of tissue fibrosis. We examined the development of tubulointerstitial fibrosis and its relationship with Transforming growt...
