Convergence of stress granules and protein aggregates in hippocampal cornu ammonis 1 at later reperfusion following global brain ischemia.
The delayed and selective vulnerability of post-ischemic hippocampal cornu ammonis (CA) 1 pyramidal neurons correlates with a lack of recovery of normal protein synthesis. Recent evidence implicates sequestration of translational machinery into protein aggregates and stress granules as factors underlying persistent translation arrest in CA1 neurons. However, the relationship between protein agg...
متن کاملHippocampal cellular stress responses after global brain ischemia and reperfusion.
Brain ischemia and reperfusion (I/R) induce neuronal intracellular stress responses, including the heat-shock response (HSR) and the unfolded protein response (UPR), but the roles of each in neuronal survival or death are not well understood. We assessed the relative expression of UPR (ATF4, CHOP, GRP78, XBP-1) and HSR-related (HSP70 and HSC70) mRNAs and proteins after brain I/R. We evaluated t...
متن کاملObestatin inhibits apoptosis and astrogliosis of hippocampal neurons following global cerebral ischemia reperfusion via antioxidant and anti-inflammatory mechanisms
Objective(s): Obestatin is a newly discovered peptide with antioxidant activities in different animal models. Recent studies have shown that Obestatin inhibits apoptosis following cardiac ischemia/reperfusion injury. Brain ischemia/reperfusion induces irreversible damage especially in the hippocampus area. This study aimed at examining the protective impact of Obestati...
متن کاملEffect of Coenzyme Q10 (ubiquinone) on hippocampal CA1 pyramidal cells following transient global ischemia/reperfusion in male wistar rat
Ischemia/Reperfusion (I/R)-induced cerebral injury has been reported as a leading cause of deathand long-term disabilities. Hippocampus is an area which is more sensitive to be affected by I/Rand hypoxic conditions. Coenzyme Q10 is a strong antioxidant which plays a role in membranestabilization. This study aims to investigate the possible role of CoQ10 in ameliorating thehistomorphological cha...
متن کاملReduction in ischemic brain injury following the administration of pentoxifylline after transient global ischemia/ reperfusion in a rat model
Background: It is well known that the hippocampus, the CA1 Pyramidal cells in particular, is selectively vulnerable during global cerebral ischemia. Recently, it is observed that pentoxifylline has a neuroprotective effect. This study explored the pharmacological relationship between ischemia-induced cell death of the hippocampus and the efficacy of a vasodilator agent (pentoxifylline) in the...
