Increased expression of collagens, transforming growth factor-β1, and -β3 in gluteal muscle contracture
BACKGROUND Gluteal muscle contracture (GMC) is a multi-factor human chronic fibrotic disease of the gluteal muscle. Fibrotic tissue is characterized by excessive accumulation of collagen in the muscle's extracellular matrix. Transforming growth factor (TGF)-beta1 and -beta2 are thought to play an important role in fibrogenesis, while TGF-beta3 is believed to have an anti-fibrotic function. We h...
متن کاملSphingosine-1-phosphate is a possible fibrogenic factor in gluteal muscle fibrosis.
Gluteal muscle contracture (GMC) is a chronic fibrotic disease of gluteal muscles due to multiple etiologies. The main pathologic process is characterized by proliferation of fibroblasts and excessive accumulation of collagen in the extracellular matrix of the muscle. Sphingosine-1-phosphate (S1P) is a bioactive sphingolipid and has been reported to be associated with various fibrotic diseases....
متن کاملRoles of TGF-β/Smad signaling pathway in pathogenesis and development of gluteal muscle contracture
PURPOSE OF THE STUDY Gluteal muscle contracture (GMC) is a chronic fibrotic disease of gluteal muscles which is characterized by excessive deposition of collagen in the extracellular matrix. Transforming growth factor (TGF)-βs have been shown to play an important role in the progression of GMC. However, the underlying mechanisms are not entirely clear. We sought to explore the expression of TGF...
متن کاملTransforming growth factor-beta1 promotes the morphological and functional differentiation of the myofibroblast.
The myofibroblast is responsible for the generation of contractile force associated with wound contraction and pathological contractures and is characterized by the presence of alpha-smooth muscle (alpha-sm) actin-containing stress fibers, vinculin-containing fibronexus adhesion complexes, and fibronectin fibrils containing the ED-A splice variant. Transforming growth factor-beta1 (TGF-beta1) c...
متن کاملRole of collagen-binding heat shock protein 47 and transforming growth factor-beta1 in conjunctival scarring in ocular cicatricial pemphigoid.
PURPOSE Submucosal fibrosis due to excessive accumulation of collagens is an important histologic feature in the pathogenesis of ocular cicatricial pemphigoid (OCP). Heat shock protein 47 (HSP47), a collagen-binding protein, plays an important role in the biosynthesis of procollagens. In the present study, we examined the role of HSP47 in conjunctival scarring in patients with OCP. METHODS Bi...
