Erythropoietin (EPO) regulates the proliferation and differentiation of erythroid cells by binding to its specific transmembrane receptor (EPOR). The presence of EPO and its receptor in the CNS suggests a different function for EPO other than erythropoiesis. The purpose of the present study was to examine EPOR expression and the role of EPO in the(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)
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)
Insulin-like growth factor-1 (IGF-1) is a brain-specific multifunctional protein involved in neuronal polarity and axonal guidance. Mature IGF-1 triggers three enzymes, mitogen-activated protein kinase (MAPK), phosphatidylinositol 3-kinase (PI3K), and phosphoinositide phospholipase C-γ (PLC-γ), which are its predominant downstream regulators. The PI3K-AKT(More)
Zinc concentrations in the dorsal horn of spinal cord are important for wound healing, neurological function, and reproduction. However, the response of the spinal cord to alterations in dietary zinc is unknown in rats after spinal cord injury (SCI). The current study explored cellular zinc levels and zinc transporter 1 (ZnT1) expression in the dorsal horn(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 Zn2+, zinc transporter, and BDNF in spinal cord injuries (SCI) is not fully understood. The purpose of this study was to investigate the expression of Zn2+, zinc transporter 1 (ZnT-1), and BDNF,(More)
OBJECTIVE Aminoguanidine (AG) can reduce brain edema and increase the recovery of neuron functions in surgical brain injury and stroke. To investigate the effect of AG on spinal cord injury (SCI) in rats and its mechanism. METHODS A total of 150 adult male Sprague Dawley rats (weighing, 230-255 g) were divided into control group (group A, 25 rats without(More)
Autophagy plays an essential role in neurodevelopment, axonal guidance, neuropathic pain remission, and neuronal survival. Inhibiting the mammalian target of rapamycin (mTOR) signaling pathway can induce the occurrence of autophagy. In this study, we initially detected the effect of probucol on autophagy after spinal cord injury (SCI) by intraperitoneally(More)
Photoinduced organic oxidation with iron (hydr)oxides in aqueous suspension has been argued with respect to two principal mechanisms: (a) photoinduced ligand-to-metal charge transfer within a surface complex and (b) semiconductor photocatalysis. In this work, the photodegradation of azo dye orange II with UV light (lambda > or = 320 nm) in the aerated(More)
