INFLUENCE OF GLYCOSAMINOGLYCANS ISOLATED FROM THE RAT LIVER WITH VARIOUS STAGES OF CARBON TETRACHLORIDE-INDUCED FIBROSIS UPON COLLAGEN FIBRILLOGENESIS IN VITRO
The influence of glycosaminoglycans (GAG) on collagen fibrillogenesis in vitro was investigated. GAG and collagen were isolated from the liver of rats treated with carbon tetrachloride at various time intervals (3-16 weeks). It was found that GAG obtained from the fibrotic liver accelerated collagen fibril formation. This effect was more evident in a solution of type I collagen than type II...
متن کاملThe ultrastructure of fibronectin fibers pulled from a protein monolayer at the air-liquid interface and the mechanism of the sheet-to-fiber transition
Fibronectin is a globular protein that circulates in the blood and undergoes fibrillogenesis if stretched or under other partially denaturing conditions, even in the absence of cells. Stretch assays made by pulling fibers from droplets of solutions containing high concentrations of fibronectin have previously been introduced in mechanobiology, particularly to ask how bacteria and cells exploit ...
متن کاملHypoxia increases the abundance but not the assembly of extracellular fibronectin during epithelial cell transdifferentiation.
Increased production and assembly of extracellular matrix proteins during transdifferentiation of epithelial cells to a mesenchymal phenotype contributes to diseases such as renal and pulmonary fibrosis. TGF-β and hypoxia, two cues that initiate injury-induced fibrosis, caused human kidney cells to develop a mesenchymal phenotype, including increased fibronectin expression and secretion. Howeve...
متن کاملStudying early stages of fibronectin fibrillogenesis in living cells by atomic force microscopy
Fibronectin (FN) is an extracellular matrix protein that can be assembled by cells into large fibrillar networks, but the dynamics of FN remodeling and the transition through intermediate fibrillar stages are still incompletely understood. Here we have used a combination of fluorescence microscopy and time-lapse atomic force microscopy (AFM) to visualize initial stages of FN fibrillogenesis in ...
متن کاملFibronectin Unfolding Revisited: Modeling Cell Traction-Mediated Unfolding of the Tenth Type-III Repeat
Fibronectin polymerization is essential for the development and repair of the extracellular matrix. Consequently, deciphering the mechanism of fibronectin fibril formation is of immense interest. Fibronectin fibrillogenesis is driven by cell-traction forces that mechanically unfold particular modules within fibronectin. Previously, mechanical unfolding of fibronectin has been modeled by applyin...
