Background: The P300 components of auditory event related potentials (ERPs) are objective measures related to information and cognitive processing. Objectives: To assess P300 ERPs in female patients with fibromyalgia (FM) in comparison with healthy age matched controls. To investigate the relationship between P300 potentials and pain threshold levels of patients, and subsequent effect of sertra...

Acetylation of proteins by p300 histone acetyltransferase plays a critical role in the regulation of gene expression. The prior discovery of an autoacetylated regulatory loop in the p300 histone acetyltransferase (HAT) domain prompted us to further explore the mechanisms of p300 autoacetylation. Here we have described a kinetic and mass spectrometric analysis of p300 HAT autoacetylation. The ra...

Background: Scant and equivocal research exists examining the effects of button-pressing on P300. Button-pressing may decrease P300 latency and amplitude. The melding of motor potentials and P300 may also confound studies of P300 topography, such as studies of temporal scalp-area asymmetries in schizophrenia. Method: P300 was measured on button-press and silent-count tasks in control subjects. ...

Neurodegenerative diseases are associated with failed proteostasis and accumulation of insoluble protein aggregates that compromise neuronal function survival. In Parkinson’s disease, a major pathological finding is Lewy bodies neurites mainly composed phosphorylated aggregated α-synuclein fragments organelle membranes. Here, we analyzed series selective inhibitors acting on multidomain protein...

p300/CBP is a transcriptional adaptor that integrates signals from many sequence-specific activators via direct interactions. Various cellular and viral factors target p300/CBP to modulate transcription and/or cell cycle progression. One such factor, the cellular p300/CBP associated factor (PCAF), possesses intrinsic histone acetyltransferase activity. Here, we demonstrate that p300/CBP is not ...
