Co-transfection of decorin and interleukin-10 modulates pro-fibrotic extracellular matrix gene expression in human tenocyte culture

چکیده
Extracellular matrix synthesis and remodelling are driven by increased activity of transforming growth factor beta 1 (TGF-β1). In tendon tissue repair, increased activity of TGF-β1 leads to progressive fibrosis. Decorin (DCN) and interleukin 10 (IL-10) antagonise pathological collagen synthesis by exerting a neutralising effect via downregulation of TGF-β1. Herein, we report that the delivery of DCN and IL-10 transgenes from a collagen hydrogel system supresses the constitutive expression of TGF-β1 and a range of pro-fibrotic extracellular matrix genes.

Activation of extracellular signal-regulated protein kinase1,2 results in down-regulation of decorin expression in fibroblasts.
Decorin is a small leucine-rich extracellular matrix proteoglycan, the expression of which is down-regulated in proliferating and malignantly transformed cells. In the present study we show that the expression of decorin in fibroblasts is suppressed by epidermal growth factor (EGF) and PMA, and that the effect of both is potently inhibited by blocking the extracellular signal-regulated protein ...
متن کاملCharacterization of tendon cell cultures of the human rotator cuff.
Rotator cuff tears are common soft tissue injuries of the musculoskeletal system that heal by formation of repair tissue and may lead to high retear rates and joint dysfunction. In particular, tissue from chronic, large tendon tears is of such degenerative nature that it may be prone to retear after surgical repair. Besides several biomechanical approaches, biologically based strategies such as...

Background: Previous studies have shown that some cytokines have protective effects on cartilage in joint diseases. In the current study, effects of IL-4 against morphological changes and tissue degradation induced by IL-1α on bovine nasal cartilage (BNC) explants were investigated. Methods: Fresh BNC samples were prepared from a slaughterhouse under sterile conditions. BNC explants culture was...

Introduction: The decorin is a myokine that modulates the growth and the development of the cancer cells through the interaction with TGF-β. The present study is aimed to evaluate the protective effects of 8 weeks interval aerobic exercise on the expression of decorin and TGF-β, and tumor volume in a typical animal of breast tumor. Materials and Methods: In a exprimental research, forty adult f...
متن کاملOptimization of Agrobacterium-mediated transformation in oyster mushroom (Pleurotus ostreatus) by vector containing human pro-insulin gene
Transferring foreign genes into mushroom mediated by Agrobacterium tumefaciens is a standard technique in genetic engineering. Recombinant human insulin has been greatly used in the treatment of type I diabetes. The production of edible mushroom derived insulin should facilitate oral delivery. In this study we used the Agrobacterium tumefaciens mediated transformation method for the transfer an...
