Massive neuronal apoptosis and accumulation of protein aggregates in the cortex and hippocampus of the brain are hallmarks of several neurodegenerative disorders, indicating ubiquitin proteasome system (UPS) dysfunction. Lactacystin, a classical proteasome inhibitor, is used to simulate ubiquitin proteasome system dysfunction in neurons to mimic(More)
Mouse neuroblastoma cell lines are often used in lieu of mouse primary neurons in ex vivo experiments, as they provide an easier platform for transfection, compared to the latter. A well-known inherent problem with this strategy is the relatively low transfection efficiency (15-30%) of mouse neuroblastoma cell lines such as neuro-2A and N1E-115. We were(More)
The involvement of cyclin-dependent kinase-5 (Cdk5) and p25, the proteolytic fragment of activator p35, has long been implicated in the development of neuron-fibrillary tangles (NFTs), a hallmark of Alzheimer's disease (AD). Findings in this area over the past decade have been highly controversial and inconclusive. Here we report unprecedented detection of(More)
