The switch from short-term to long-term facilitation of the synapses between sensory and motor neurons mediating gill and tail withdrawal reflexes in Aplysia requires CREB-mediated transcription and new protein synthesis. We isolated several downstream genes, one of which encodes a neuron-specific ubiquitin C-terminal hydrolase. This rapidly induced gene(More)
Long-term synaptic plasticity requires both gene expression in the nucleus and local protein synthesis at synapses. The effector proteins that link molecular events in the cell body with local maintenance of synaptic strength are not known. We now show that treatment with serotonin (5-HT) that produces long-term facilitation induces the Aplysia eukaryotic(More)
In this study, we found that two amino acids reacted with 2,5-hexanedione to form new reaction products in vitro, respectively. In the reaction of beta-alanine and 2,5-hexanedione, a reaction product was obtained and analyses of obtained results showed it was 3-(2,5-dimethyl-1H-pyrrol-1-yl)propanoic acid; in the reaction of glycine and 2,5-hexanedione, a(More)
Fusion plasmid pSV-Luc20 and pSV-Luc19 were constructed by using the larger BamHI restricted fragments of plasmid pDO432 containing the firefly luciferase (luc) gene and HindIII-BamHI restricted fragment of plasmid pSVK100 containing the SV-40 promoter as insert and vector, respectively. The fusion plasmid had different ligation orientations between the(More)
