Obestatin 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 کاملErythropoietin prevents neuronal apoptosis after cerebral ischemia and metabolic stress.
Erythropoietin (EPO) promotes neuronal survival after hypoxia and other metabolic insults by largely unknown mechanisms. Apoptosis and necrosis have been proposed as mechanisms of cellular demise, and either could be the target of actions of EPO. This study evaluates whether antiapoptotic mechanisms can account for the neuroprotective actions of EPO. Systemic administration of EPO (5,000 units/...
متن کاملApoptosis in a neonatal rat model of cerebral hypoxia-ischemia.
BACKGROUND AND PURPOSE The mechanisms of excitotoxic cell death in cerebral ischemia are poorly understood. In addition to necrosis, apoptotic cell death may occur. The purpose of this study was to determine whether an established model of cerebral hypoxia-ischemia in the neonatal rat demonstrates any features of apoptosis. METHODS Seven-day-old neonatal rats underwent bilateral, permanent ca...
متن کاملEffects of Usnic Acid on Apoptosis and Expression of Bax and Bcl-2 Proteins in Hippocampal CA1 Neurons Following Cerebral Ischemia-Reperfusion
Introduction: Cerebral ischemia-reperfusion causes complex pathological mechanisms that lead to tissue damage, such as neuronal apoptosis. Usnic acid is a secondary metabolite of lichen and has various biological properties including antioxidant and anti-inflammatory activities. This study aimed to investigate the neuroprotective effects of usnic acid on apoptotic cell death and apoptotic-relat...
متن کاملAutophagy Upregulation and Apoptosis Downregulation in DAHP and Triptolide Treated Cerebral Ischemia
It has previously been demonstrated that ischemic stroke activates autophagy pathways; however, the mechanism remains unclear. The aim of this study is to further investigate the role that autophagy plays in cerebral ischemia. 2, 4-diamino-6-hydroxy-pyrimidine (DAHP), for its nitric oxide synthase (NOS) inhibiting neuroprotective effect, and triptolide (TP), for its anti-inflammatory property, ...
