Wounds and wound healing have always been one of the most important subjects that experimental researches were dedicated to. Simvastatin has been used for long as a common lipid lowering agent which was reported to have some pleiotropic effects such as antioxidation, anti-inflammation and immunomodulation. In this study we aimed to determine the effect of simvastatin on wound healing process in...

BACKGROUND Prostacyclin analogs are potent vasodilators and possess anti-inflammatory properties. However, the effect of prostacyclin on extracellular matrix (ECM) in COPD is not well known. Collagen fibrils and proteoglycans are essential ECM components in the lung and fibroblasts are key players in regulating the homeostasis of ECM proteins. The aim was to study the synthesis of prostacyclin ...

We have previously shown that estradiol suppresses the synthesis of type I collagen by murine mesangial cells grown in the presence of serum via activation of the transcription factor activator protein-1 (AP-1). We hypothesized that estradiol upregulates AP-1 via activation of the mitogen-activated protein (MAP) kinase cascade, a signal transduction pathway that regulates AP-1 activity. Estradi...

Collagen types I and III, coded by COL1A1/COL1A2 and COL3A1 genes, are the major fibrillar collagens produced by fibroblasts, including cardiac fibroblasts of the adult heart. Characteristic for different cardiomyopathies is a remodeling process associated with an upregulation of collagen synthesis, which leads to fibrosis. We report identification of three mRNA-binding proteins, heterogeneous ...

We have previously shown that estradiol suppresses types I and IV collagen synthesis by mesangial cells grown in the presence of serum. In the present study, we examined the interaction between estradiol and transforming growth factor-β (TGF-β) on collagen IV synthesis. In a luciferase reporter gene construct containing the type IV collagen promoter and α1-chain regulatory sequences, we found t...

OBJECTIVE The treatment of cartilage defects with matrix-embedded autologous chondrocytes is a promising method to support the repair process. In this study we gathered quality parameters of collagen I matrices and embedded autologous chondrocytes at the time of transplantation We determined number, morphology, and distribution of matrix-embedded chondrocytes as well as their synthesis performa...

We have developed a collagen-mRNA platform for controllable protein production that is intended to be less prone to the problems associated with commonly used mRNA therapy as well as with collagen skin-healing procedures. A collagen mimic was constructed according to a recombinant method and was used as scaffold for translating mRNA chains into proteins. Cysteines were genetically inserted into...

In the present study, to investigate the effect of glucosamine, a component of glycosaminoglycans with a chondroprotective action, on articular cartilage in athletes, we looked at soccer players, who expose their joints to excessive motion and loading, and compared the levels of biomarkers for type II collagen degradation (CTX-II) and type II collagen synthesis (CPII) between soccer players and...
