The study investigated the mechanism of the up-regulation of aquaporin-4 (AQP4) and aquaporin-1 (AQP1) expression induced by spinal cord injury (SCI). Using adult rat spinal cord injury model, it was found that up-regulation of hypoxia inducible factor-1α (HIF-1α), vascular endothelial growth factor (VEGF), AQP4, and AQP1 in response to spinal cord injury(More)
Responsible for orchestrating cellular energy production, mitochondria are central to the maintenance of life and the gatekeepers of cell death. Its morphology is dynamic and controlled by continual and balanced fission and fusion events. In this study, we analyzed the mitochondrial dynamics and functions after spinal cord injury in rats and further to(More)
Salvianolic acid B (Sal B), a bioactive compound isolated from the Chinese medicinal herb danshen, is commonly used for the prevention and treatment of cardiovascular disease. The present study was performed to investigate the effect of Sal B on the blood–spinal cord barrier (BSCB) after spinal cord injury (SCI) in a rat model. Sal B (1, 10, and 50 mg/kg(More)
Mitochondrial division inhibitor 1 (Mdivi-1) is the most effective pharmacological inhibitor of mitochondrial fission. Spinal cord injury (SCI) is a common and serious trauma, which lacks efficient treatment. This study aimed to detect the role of Mdivi-1 in neuronal injury and its underlying mechanism after acute SCI (ASCI) in rats. Western blot analysis(More)
Spinal cord repair is a challenging task that has puzzled clinical specialists and scientists for a long time. Zinc plays an important role in regulating the expression of brain-derived neurotrophic factor (BDNF) in nervous system, which can improve the pathological state of neurons and promote regeneration of injured neurons, reduce neuronal apoptosis. Our(More)
Zinc plays an important role in regulating the expression of brain-derived neurotrophic factor (BDNF) and its receptor in nervous system, but the correlation among Zn(2+), zinc transporter, and BDNF in spinal cord injuries (SCI) is not fully understood. The purpose of this study was to investigate the expression of Zn(2+), zinc transporter 1 (ZnT-1), and(More)
Neural stem cells (NSCs) are deemed to be a potential cell therapy for brain and spinal cord reconstruction and regeneration following injury. In this study, we investigated the role of nanofibrous scaffolds on NSCs-derived neurons in the formation of neural networks. Miniature excitatory postsynaptic currents (mEPSCs) were recorded using the whole-cell(More)
Previous studies have shown that curcumin (Cur) can produce potent neuroprotective effects against damage due to spinal cord injury (SCI). However, whether Cur can preserve the function of the blood-spinal cord barrier (BSCB) is unclear. The present study was performed to investigate the mechanism underlying BSCB permeability changes, which were induced by(More)
Collapsin response mediator protein 2 (CRMP2) is a brain-specific multifunctional adaptor protein involved in neuronal polarity and axonal guidance. Our previous results showed CRMP2 may be involved in the hypoxic preconditioning and ischemic injury, but the mechanism was not clear. This study explored whether CRMP2 was involved in NMDA-induced neural(More)
This study was performed to investigate the effect of bone marrow stromal cells (BMSCs) combined with green tea polyphenols (GTPs) on the blood-spinal cord barrier (BSCB) permeability after spinal cord injury (SCI) in the rat model. In the model of SCI rats, we found that the water content and the BSCB permeability were decreased by BMSCs and GTPs(More)
