An increase in neuronal glutamate transporter expression after nerve injury was demonstrated by means of differential display PCR (DD-PCR) coupled with in situ hybridization. DD-PCR was carried out to compare differences in expression of mRNAs between axotomized and normal hypoglossal motoneurons in the rat. The expression of several gene fragments were(More)
An increase in cyclin G expression after nerve injury was demonstrated by differential display PCR, carried out to compare references in expression of mRNAs between axotomized and normal hypoglossal motoneurons in the rat. The nerve injury dramatically upregulated the expression of cyclin G mRNA in the motoneurons during the early phase of the nerve(More)
Numerous studies have suggested that growth factors and cytokines play an important role in the survival of injured neurons and in neurite elongation. Therefore, intracellular signalling pathways activated by growth factors and cytokine receptors play an important role in neuronal survival or for the re-establishment of connection. Since the JAK (janus(More)
Up-regulation of ERK (extracellular signal-regulated kinase or MAP kinase) and MEK (ERK kinase or MAPK kinase) expression after rat facial nerve injury was demonstrated by in situ hybridization histochemistry and immunohistochemistry. These two enzymes play roles in one of the major intracellular signal cascade pathways involving receptor tyrosine kinase(More)
Using in situ hybridization histochemistry and immunohistochemistry, the present study examines the cooperative regulation of transcription of molecules involved in the Ras-signal and the cAMP dependent protein kinase (PKA) pathways during peripheral nerve regeneration in rats. Injury to hypoglossal motor neurons resulted in an increase in extracellular(More)
The differential display method was applied to identify gene expression, which is especially up-regulated in denervated skeletal muscle. Total RNA from normal and denervated rat facial muscles (muscles zygomaticus, levator nasolabialis and caninus) was isolated, amplified by polymerase chain reaction (PCR) using certain primers and separated by(More)
