Abstract
Focal adhesion kinase (FAK) and proline-rich tyrosine kinase (PYK2) are two related non-receptor tyrosine kinases which are thought to play a role in transducing extracellular matrix (ECM)-derived survival signals into cells. The functions of FAK and PYK2 are linked to autophosphorylation of their specific tyrosine residues, Tyr-397 in FAK and Tyr-402 in PYK2, and then association with different signalling proteins which mediate activation of downstream targets such as ERK and JNK mitogen-activated kinase cascades. Thus, modulation of FAK as well as PYK2 autophosphorylation may affect several intracellular pathways and may participate in a variety of pathological settings. The present study provides a systematic investigation of the influence of experimental ischemia, induced by oxygen-glucose-deprivation, on the FAK- and PYK2-mediated signalling in organotypic hippocampal slice cultures. OGD induced primary down-regulation of FAK and PYK2 autophosphorylation (at Tyr 397 and Tyr 402, respectively) at 24-48 h of reoxygenation was accompanied by the diminution of phosphorylation/activation of Src and JNK. In contrast, the activity of Akt and ERK1/2 remained on the control level. It indicates that Akt kinase as well as ERK1/2 does not interfere with OGD-induced neuronal damage. The inhibition of the early step of FAK and PYK2 activation demonstrated by the decrease of tyrosine autophosphorylation may comprise an important portion of the response expressed by modulation of some coupled signal transduction pathways.

Abstract
It is well-established that hyperthermia increases neuronal death and worsens stroke outcome. However, little is known about the mechanisms of how hyperthermia is involved in this neuronal death process. In the present study, we examined how temperature increase exacerbates neuronal death using a model of chemical ischemia. Chemical ischemia was induced by treating SH-SY5Y neuroblastoma cells with sodium azide and deoxyglucose. Temperature increase was treated by placing the cells at 37°C (control) and 41°C (experimental). Cell survival was determined by trypan blue assay and ATP levels were measured with ATP assay kits. Protein expression was detected by western blot. Treatment with sodium azide resulted in cell death in a dose-responsive manner. Increased temperature worsened the ATP depletion and cell volume shrinkage. Temperature increase also enhanced ER stress as demonstrated by the elevated level of phospho-eIF2α and C/EBP homologous protein (CHOP). Inhibition of CHOP expression significantly decreased sodium azide-induced neuronal death. In addition, the increased temperature intensified the activation of caspase-3, an apoptotic effector protease, and inhibition of capspase-3 significantly reduced cell death. These findings support that temperature increase worsened the neuronal death by depleting intracellular ATP, inducing ER stress response and activating apoptotic signal transduction.

Abstract
To investigate the role of purinergic P2 receptors under ischemia, we studied the effect of P2 receptor antagonists on synaptic transmission and mitogen-activated protein kinase (MAPK) activation under oxygen and glucose deprivation (OGD) in rat hippocampal slices. The effect of the P2 antagonists pyridoxalphosphate-6-azophenyl-2',4'-disulfonate (PPADS, unselective, 30 μm), N( 6) -methyl-2'-deoxyadenosine-3',5'-bisphosphate (MRS2179, selective for P2Y(1) receptor, 10 μm), Brilliant Blue G (BBG, selective for P2X(7) receptor, 1 μm), and 5-[[[(3-phenoxyphenyl)methyl][(1S)-1,2,3,4-tetrahydro-1-naphthalenyl]amino]carbonyl]-1,2,4-benzenetricarboxylic acid (A-317491, selective for P2X(3) receptor, 10 μm), and of the newly synthesized P2X(3) receptor antagonists 2-amino-9-(5-iodo-2-isopropyl-4-methoxybenzyl)adenine (PX21, 1 μm) and 2-amino-9-(5-iodo-2-isopropyl-4-methoxybenzyl)-N( 6)-methyladenine (PX24, 1 μm), on the depression of field excitatory postsynaptic potentials (fEPSPs) and anoxic depolarization (AD) elicited by 7 min of OGD were evaluated. All antagonists significantly prevented these effects. The extent of CA1 cell injury was assessed 3 h after the end of 7 min of OGD by propidium iodide staining. Substantial CA1 pyramidal neuronal damage, detected in untreated slices exposed to OGD injury, was significantly prevented by PPADS (30 μm), MRS2179 (10 μm), and BBG (1 μm). Western blot analysis showed that, 10 min after the end of the 7 min of OGD, extracellular signal-regulated kinase (ERK)1/2 MAPK activation was significantly increased. MRS2179, BBG, PPADS and A-317491 significantly counteracted ERK1/2 activation. Hippocampal slices incubated with the ERK1/2 inhibitors 1,4-diamino-2,3-dicyano-1,4-bis(2-aminophenylthio)butadiene (U0126, 10 μm) and α-[amino[(4-aminophenyl)thio]methylene]-2-(trifluoromethyl) benzeneacetonitrile (SL327, 10 μm) showed significant fEPSP recovery after OGD and delayed AD, supporting the involvement of ERK1/2 in neuronal damage induced by OGD. These results indicate that subtypes of hippocampal P2 purinergic receptors have a harmful effect on neurotransmission in the CA1 hippocampus by participating in AD appearance and activation of ERK1/2.

Abstract
An intracellular calcium ([Ca(2+)](i)) increase is involved in sodium azide (NaN(3))-induced neurotoxicity, an in vitro model of brain ischemia. In this study the questions of possible additional sources of calcium influx, besides glutamate receptor activation, and of the time-course of NaN(3) effects have been addressed by measuring [Ca(2+)](i) in rat primary cortical cultures with the FURA-2 method. Basal [Ca(2+)](i) of neuronal populations was concentration-dependently increased 30 min, but not 24h, after a 10-min NaN(3) (3-30 mM) treatment; conversely, the net increase induced by electrical stimulation (10Hz, 10s) was consistently reduced. All the above effects depended on glutamate release and consequent NMDA receptor activation, since the NMDA antagonist MK-801 (1 microM) prevented them, and the spontaneous efflux of [(3)H]-d-aspartate from superfused neurons was concentration-dependently increased by NaN(3). In single neuronal cells, NaN(3) application progressively and concentration-dependently increased [Ca(2+)](i) (to 177+/-5% and 249+/-7% of the controls, 4 and 12 min after a 10mM-treatment, respectively). EGTA (5mM) pretreatment reduced the effect of 10mM NaN(3) (to 118+/-5% at 4 min, and to 148+/-10% at 12 min, respectively), while 1 microM cyclosporin A did not. Both MK-801 and CNQX (a non-NMDA glutamate antagonist, 10 microM) prevented NaN(3) effect at 4 min (to 147+/-8% and 153+/-5%, respectively), but not at 12 min after NaN(3) treatment. Conversely, 10 microM verapamil and 0.1 microM omega-conotoxin (L- and N-type calcium channel blockers, respectively) significantly attenuated NaN(3) effects at 12 min (to 198+/-8% and 164+/-5%, respectively), but not at 4 min; the P/Q-type calcium channel blocker, agatoxin, 0.3 microM, was ineffective. These findings show that the predominant source of calcium increase induced by NaN(3) is extracellular, involving glutamate receptor activation in a first step and calcium channel (mainly of the N-type) opening in a second step.
