The P300-based brain–computer interfaces (P300 BCI) allow the user to select commands by focusing on them. technology involves electroencephalographic (EEG) representation of event-related potentials (ERP) that arise in response repetitive external stimulation. Conventional procedures for ERP extraction and analysis imply identical stimuli produce responses. However, floating onset EEG reaction...

BACKGROUND Despite advances in the treatment of heart failure, mortality remains high, particularly in individuals with diabetes. Activated transforming growth factor beta (TGF-β) contributes to the pathogenesis of the fibrotic interstitium observed in diabetic cardiomyopathy. We hypothesized that high glucose enhances the activity of the transcriptional co-activator p300, leading to the activa...

Prostate cancer is the most frequent non-skin cancer in men. Although the mechanisms involved in the progression of prostate cancer are not entirely understood, androgen receptor has been shown to play an important role. Androgen receptor is expressed in both early and late-stage prostate cancer. Also, androgen-regulated pathways are thought to be active as evidenced by elevated levels of prost...

The transcriptional cofactor p300 has histone acetyltransferase activity (HAT) and has been reported to participate in chromatin remodeling and DNA repair. We hypothesized that targeting p300 can enhance the cytotoxicity of gemcitabine, which induces pancreatic cancer cell apoptosis by damaging DNA. Expression of p300 was confirmed in pancreatic cancer cell lines and human pancreatic adenocarci...

PURPOSE To investigate the correlation among p300, CBP and MLL expression and the clinicopathological characteristics in resected SCLC patients. METHODS Two hundred and twenty-two resected SCLC patients were included in this study. We evaluated p300, CBP and MLL expression by immunohistochemistry. RESULTS Patients with high p300 expression had shorter OS and DFS than those with low p300 exp...

BACKGROUND The acceleration forces infringing the cervical spine in whiplash injury are frequently associated with multiple cerebral symptoms. The purpose of this study was to determine whether there is a correlation between cerebral perfusion findings, P300 recording (an electrophysiologic marker of cognitive ability), and neuropsychological tests in patients with whiplash injury. METHODS Tw...

Muscle proteolysis during sepsis and other catabolic conditions is, at least in part, regulated by glucocorticoids. Dexamethasone-treated myotubes are a commonly used in vitro model of muscle wasting. We reported recently that treatment of cultured L6 myotubes with dexamethasone resulted in increased gene and protein expression of the nuclear cofactor p300 but it is not known whether glucocorti...

Cyclic adenosine monophosphate response element binding (CREB)-binding protein (CBP) and p300 are multidomain transcriptional coactivators that help assemble large regulatory complexes at sites of active transcription. Nullizygosity of CBP or p300 results in pervasive defects in hematopoiesis. To systematically assess the structural domains of p300 required for normal hematopoiesis, we used rec...

AIM In the present study, the P300 component of the emotion-loaded visual event-related potential in response to photographs of babies crying or smiling was measured to evaluate cognitive function in elderly subjects, including those with dementia. METHODS The subjects were 48 elderly people who consulted a memory disorder clinic. The visual event-related potential was measured using oddball ...

NF-κB plays a vital role in cellular immune and inflammatory response, survival, and proliferation by regulating the transcription of various genes involved in these processes. To activate transcription, RelA (a prominent NF-κB family member) interacts with transcriptional co-activators like CREB-binding protein (CBP) and its paralog p300 in addition to its cognate κB sites on the promoter/enha...
