It is known that the activation of N-methyl-D-aspartate (NMDA) receptors leads to an increase in extracellular taurine concentration in different brain regions. The mechanism that mediates this effect is not totally understood. In this study, rat hippocampal slices were used to determine the dependence of NMDA-induced taurine release on extracellular(More)
To assess the possible inhibitory action of nicotinamide adenine dinucleotides on the synaptic release of glutamate, electrophysiological and biochemical experiments were performed on rat hippocampal slices. Perfusion of adenosine, beta-nicotinamide adenine dinucleotide (NAD) or beta-nicotinamide adenine dinucleotide phosphate (NADP), reversibly inhibited(More)
The tsA58 allele of SV40 large T antigen has the ability to immortalize cells, which is thought to be due, in part, to binding of p53 protein by T antigen at 33 degrees C. At the nonpermissive temperature (39.5 degrees C), it is thought that p53 is released, inducing growth arrest, vulnerability to apoptosis, and loss of the immortal phenotype. In cell(More)
