3-Nitrotyrosine inhibits fibroblast-mediated collagen gel contraction and chemotaxis.
Reactive nitrogen species induce tissue inflammation and nitrate tyrosine residues of various kinds of proteins. Recent studies have established that the free amino acid form of 3-nitrotyrosine induces cytotoxity and growth inhibition and alters the cellular function in cultured cells. The aim of this study was to evaluate whether 3-nitrotyrosine could affect tissue remodelling in fibroblasts. ...
متن کاملPermissive effect of fibronectin on collagen gel contraction mediated by bovine trabecular meshwork cells.
PURPOSE The effect of fibronectin on the contractility of trabecular meshwork (TM) cells was investigated. METHODS The contractility of bovine TM cells was evaluated by culture of the cells in a collagen gel and measurement of the change in the diameter of the gel under various conditions. The formation of stress fibers and the localization of integrin alpha5 and beta1 chains (which together ...
متن کاملSFS, a novel fibronectin-binding protein from Streptococcus equi, inhibits the binding between fibronectin and collagen.
The obligate parasitic bacterium Streptococcus equi subsp. equi is the causative agent of strangles, a serious disease of the upper respiratory tract in horses. In this study we have, using shotgun phage display, cloned from S. equi subsp. equi and characterized a gene, called sfs, encoding a protein termed SFS, representing a new type of fibronectin (Fn)-binding protein. The sfs gene was found...
متن کاملModulation of collagen gel contraction by decorin.
The small dermatan sulphate protein decorin interacts via its core protein with fibrillar collagens, and its glycosaminoglycan chains were proposed to be capable of self-association. It was therefore of interest to study the role of decorin in the contraction of cell-populated collagen lattices. Stable transfection of dihydrofolate reductase-deficient CHO cells with decorin cDNA resulted in imp...
متن کاملHypertrophic scar fibroblasts accelerate collagen gel contraction.
Excessive contraction of hypertrophic scar and subsequent contracture formation are a formidable problem after thermal injury. A comparison between fibroblasts from hypertrophic scar and normal skin was made with the use of fibroblast-populated collagen lattices as a measure of cellular generated contractile forces. Hypertrophic scar and normal skin fibroblasts were mixed with soluble tendon co...
