We examined calcitonin gene-related peptide (CGRP) expression dynamics in the dorsal root ganglia (DRGs) and spinal cords of adult rats subjected to one of the following three types of unilateral sciatic nerve injury: crush (SNC), ligation (SNL), or transection combined with subsequent neurorrhaphy (SNT). Following SNC, CGRP immunoreactivity (IR) was(More)
OBJECTIVE To explore the effects of exogenous transforming growth factor-beta 1 (TGFbeta1) on peripheral nerve regeneration after the peripheral nerve injury and if TGFbeta1 regulates the expression of basic fibroblast growth factor (bFGF) in the anterior horn motoneurons of spinal cord during regeneration. METHODS Forty-eight rats were crushed on the(More)
MicroRNAs (miRNAs) play an important role in the development, differentiation, proliferation, survival, and oncogenesis of cells and organisms including nervous system. However, the role of miRNAs in primary neurons of dorsal root ganglion (DRG) after injury was not clear. In this study, a miRNA microarray analysis was performed, and a total of 21 miRNAs(More)
Hepatocyte growth factor (HGF) and its receptor c-Met play pivotal roles in post-traumatic regeneration of the nervous system. However, following peripheral nerve injury, the role and regulation of the HGF/c-Met system is less clear. Therefore, using a sciatic nerve ligation (SNL) model, spatiotemporal changes in HGF and c-Met expression were detected in(More)
Robos are transmembrane receptors that mediate Slit signaling to repel growth cone outgrowth and neural migration in the developing central nervous system. Their distribution and function in the peripheral nervous system remains unclear. In the present study, we examined expression of Slit1 and Robo2 in adult rat dorsal root ganglion (DRG), spinal cord and(More)
It was the aim of the present study to characterize the modulatory effect of muscarinic agonists on the overflow of norepinephrine and neuropeptide Y (NPY) from the in situ perfused guinea pig heart, induced by electrical stimulation of the left stellate ganglion (6 Hz, 5 V, 1 min). The muscarinic agonists oxotremorine (0.01-1 microM) and carbachol (0.1-10(More)
The Slit-Robo GTPase-activating proteins (srGAPs) play an important role in neurite outgrowth and axon guidance; however, little is known about its role in nerve regeneration after injury. Here, we studied the expression of srGAPs in mouse dorsal root ganglia (DRG) following sciatic nerve transection (SNT) using morphometric and immunohistochemical(More)
OBJECTIVE To explore effect of srGAP3 promotes neurite outgrowth of dorsal root ganglion neurons. METHODS In this study, expression of Slit1 was observed predominantly in the glia, while expression of Robo2 and srGAP3 was detected in sensory neurons of postnatal rat cultured dorsal root ganglion (DRG). Furthermore, upregulation of srGAP3 following sciatic(More)
