[ 1 ] - Effect of Chondroitinase ABC Enzyme on Glial Fibrillary Acidic Protein, Chondroitin Sulfated Proteoglycans and Chondroitin 4-Sulfate Levels in an Animal Model of Spinal Cord Injury
Background: Following spinal cord injury, reactive astrocytes upregulate chondroitin sulfate proteoglycans (CSPGs) which act as a barrier to neuronal repair and regeneration. Therefore, enzymatic digestion of CSPGs by chondroitinase ABC (cABC) is a key strategy in the treatment of spinal cord injury. Furthermore, cABC has been shown to attenuate post spinal cord injury inflamma...
[ 2 ] - Downregulation of Matrix Metalloproteinases 2 and 9 is Involved in the Protective Effect of Trehalose on Spinal Cord Injury
Upregulation of matrix metalloproteinases (MMPs), in particular MMP-2 and MMP-9 contributes to secondary pathogenesis of spinal cord injury (SCI) via promoting inflammation. Recently, we reported that trehalose suppresses inflammatory responses following SCI. Therefore, we investigated the effect of trehalose on MMP-2 and MMP-9 expression in SCI. A weight-drop contusion SCI was induced in male ...
[ 3 ] - Effect of Trehalose on the Expression of Heat Shock Protein 70 Gene in PC12 Cells Treated with Hydrogen Peroxide
Background and purpose: Oxidative stress is implicated in the pathogenesis of various diseases, including neurological disorders. In such stressful conditions, heat shock protein 70 (HSP70) protects cells, thus its pharmacological induction can be protective. The disaccharide trehalose exhibits various beneficial effects, including antioxidative effect. However, its impact on HSP70 is not obvio...
[ 4 ] - Effect of Trehalose on Neurocan and Neural-Glial Antigen 2 Genes Expression in Rats with Spinal Cord Injury
Background: Chondroitin sulfate proteoglycans (CSPGs) are the major cause of axonal regeneration failure at the site of lesion in spinal cord injury (SCI). Inflammation is believed to stimulate the upregulation of CSPGs expression. Recent evidence showed that trehalose reduces the development of inflammation in SCI. The aim of this study was to investigate the effect of trehalo...
[ 5 ] - Thermostabilized chondroitinase ABC Promotes Neuroprotection after Contusion Spinal Cord Injury
Background: Chondroitinase ABC (cABC), due to its loosening impact on the extracellular matrix scaffold, has been used to enhance regeneration of injured axonal tracts after spinal cord injury (SCI). However, cABC thermal instability at physiological temperature has limited its clinical application. The disaccharide trehalose has been shown to increase the stability of cABC in body temperature....
[ 6 ] - Protective Effect of Trehalose Against H2O2-induced Cytotoxicity and Oxidative Stress in PC-12 Cell Line and the Role of Heat Shock Protein-27
Background: Oxidative stress has been shown to be an important factor, which plays a significant role in the pathogenesis of neurodegenerative disorders. Heat Shock Protein-27 (HSP-27) has been implicated in antioxidant responses against oxidative stress. Trehalose is a natural disaccharide widely used in a variety of food products with demonstrated protective effects against several neurodegen...
