It is well known that trauma is frequently accompanied by spontaneous functional recovery after spinal cord injury (SCI), but the underlying mechanisms remain elusive. In this study, BBB scores showed a gradual return of locomotor functions after SCT. Proteomics analysis revealed 16 differential protein spots in the gastrocnemius muscle between SCT and(More)
BACKGROUND AIMS The neuroprotective effects of olfactory ensheathing cells (OECs) after transplantation have largely been known in the injured nervous system. However, the underlying mechanisms still must be further elucidated. We explored the effects of OEC transplantation on the recovery of neurophysiologic function and the related anti-apoptosis(More)
Spinal cord injury (SCI) often results in motor disability concomitant with limit neuroplasticity; the underlying mechanism, however, is still unclear. This study established spinal cord transection rats model (T10), then performed cDNA microarray analysis and found that vimentin located in astrocytes was increased significantly in scar tissues after(More)
Neuroregeneration and apoptosis are two important pathophysiologic changes after spinal cord injury (SCI), but their underlying mechanisms remain unclear. MicroRNAs (miRNAs) play a crucial role in the regulation of neuroregeneration and neuronal apoptosis, research areas that have been greatly expanded in recent years. Here, using miRNA arrays to profile(More)
Acetylcholine receptors (AChRs) serve as connections between motor neurons and skeletal muscle and are essential for recovery from spinal cord transection (SCT). Recently, microRNAs have emerged as important potential biotherapeutics for several diseases; however, whether miRNAs operate in the modulation of AChRs remains unknown. We found increased AChRs(More)
Spinal cord injury (SCI) often causes neurological deficits with poor recovery; the treatment, however, is far from satisfaction, and the mechanisms remain unclear. Using immunohistochemistry and western blotting analysis, we found α-synuclein (SNCA) was significantly up-regulated in the spinal caudal segment of rats subjected to spinal cord transection at(More)
Patients with tumors that metastasize to bone frequently suffer from debilitating pain, and effective therapies for treating bone cancer are lacking. This study employed a novel strategy in which herpes simplex virus (HSV) carrying a small interfering RNA (siRNA) targeting platelet-derived growth factor (PDGF) was used to alleviate bone cancer pain. HSV(More)

Nicotinamide N-methyltransferase (NNMT) transfers the methyl from S-adenosyl-L-methionine (SAM) to nicotinamide (NA) to produce S-adenosyl-L-homocysteine (SAH) and 1-methylnicotinamide (MeN). NNMT has been implicated in a variety of diseases; however, the role of NNMT in drug addiction is largely unknown. Here, we found that the expression of Nnmt was(More)
Spinal cord injury (SCI) is frequently accompanied by a degree of spontaneous functional recovery. The underlying mechanisms through which such recovery is generated remain elusive. In this study, we observed a significant spontaneous motor function recovery 14 to 28 days after spinal cord transection (SCT) in rats. Using a comparative proteomics approach,(More)
