The protective effect of a L-type calcium channel blocker, nimodipine, on cell injury induced by oxygen-glucose deprivation (OGD) in PC12 cells was investigated. PC12 cells were exposed to in-vitro oxygen-glucose deprivation (30 minutes and 60 minutes respectively) in the presence or absence of nimodipine (10mM/L) in three different time schedules (pre-24h, pre-3h and concurrently). Cellular vi...
Kevin C. H. Pang, Advisor J. Devin McAuley, Co-Chair The present series of studies examined effects of MK-801, an NMDA antagonist, on short-interval timing in rats. The first study used two experiments to examine timing performance using the peak-interval (PI) and PI-gap procedures during chronic exposure of MK801. The first of these experiments investigated the effects of three MK-801 doses (0...
Okadaic acid (OKA) is a potent inhibitor of protein phosphatases 1/2A (PP2A). Inhibition of PP2A leads to hyperphosphorylation of Tau protein. Hyperphosphorylated Tau protein is present in intraneuronal neurofibrillary tangles a characteristic feature of neuropathology of Alzheimer's disease. Intracerebroventricular (ICV) administration of OKA causes neurotoxicity, which is associated with incr...
Brain-derived neurotrophic factor (BDNF) through TrkB activation is central for brain functioning. Since the demonstration that plasmin is able to process pro-BDNF to mature BDNF and that these two forms have opposite effects on neuronal survival and plasticity, a particular attention has been paid to the link between tissue plasminogen activator (tPA)/plasmin system and BDNF metabolism. Howeve...
PURPOSE Nitric oxide (NO) has been known as an important regulator of osteoblasts and periodontal ligament cell activity. This study was performed to investigate the relationship between NO-mediated cell death of human periodontal ligament fibroblasts (PDLFs) and N-methyl-D-aspartic acid (NMDA) receptor antagonist (+)-5-methyl-10, 11-dihydro-5H-dibenzo[a,d]cyclohepten-5, 10-imine hydrogen malea...
Fetal alcohol exposure results in cognitive and neurobehavioral deficits, but the effects of modifying genetic loci on the severity of these sequelas have not been well characterized. Although the cAMP signaling pathway has been shown to be an important modulator of ethanol sensitivity in adult mice, its potential role in modulating ethanol-induced neurodegeneration has not been examined. Adeny...
