The purpose of this study was to investigate the effects of limb ischemic preconditioning (LIP) on apoptosis of pyramidal neurons in the CA1 hippocampus induced by global cerebral ischemia-reperfusion in rats. Forty-six rats whose bilateral vertebral arteries were occluded permanently were assigned to one of four groups: sham group, limb ischemia group, cerebral ischemia group and LIP group. LI...
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...
Apoptosis, a major pathogenesis of cerebral ischemia, is closely associated with the dysregulation of MAPK/ERK signaling pathway. The transplantation of neural stem cells (NSCs), as a therapeutic target of cerebral ischemia, could repair missing cells and the activation of endogenous cells to provide "self-repair". However, the neuroprotective mechanism of the transplantation of NSCs against ce...
We investigated the role of the Wnt signaling pathway in cerebral ischemia/reperfusion injury by examining β-catenin and glycogen synthase kinase-3β protein expression in the rat hippocampal CA1 region following acute cerebral ischemia/reperfusion. Our results demonstrate that cell apoptosis increases in the CA1 region following ischemia/reperfusion. In addition, β-catenin and glycogen synthase...
Objective(s): This work aimed to assess the effect of 10 new chromon-3-aldehyde derivatives on changes of mitochondrial function under the conditions of brain ischemia in rats. Materials and Methods: The work was executed on BALB/c male-mice (acute toxicity was evaluated) and male Wistar rats, which were used to model cerebral ischemia b...
Kallikrein/kinin has been shown to protect against ischemia/reperfusion-induced myocardial infarction and apoptosis. In the present study, we examined the potential neuroprotective action of kallikrein gene transfer in cerebral ischemia. Adult, male Sprague-Dawley rats were subjected to a 1-hour occlusion of the middle cerebral artery followed by intracerebroventricular injection of adenovirus ...
Chemokine-like factor 1 (CKLF1) is a novel C-C chemokine, and plays important roles in immune response and brain development. In previous study, we have found that the expression of CKLF1 increased after focal cerebral ischemia and inhibition of CKLF1 using antagonist C19 peptide protected against cerebral ischemia. However, few studies have focused on the role of CKLF1 on neuronal apoptosis. T...
We investigated the effects of nilvadipine and amlodipine on the cerebral ischemia-induced impairment of spatial memory in 8-arm radial maze performance and hippocampal CA1 apoptosis in rats. Single cerebral ischemia impaired memory without inducing apoptosis. In these rats, neither nilvadipine nor amlodipine at 3.2 mg/kg, i.p. improved the impaired memory. On the other hand, repeated cerebral ...
The role of resveratrol in cerebral ischemia/reperfusion injury is not well understood. The aim of this study was to investigate whether resveratrol modulates inflammation and oxidative stress in cerebral ischemia/reperfusion injury in mice. Rats were subjected to 2 h of transient middle cerebral artery occlusion (MCAO), followed by 24 h of reperfusion. Rats were randomly exposed to sham operat...
global cerebral ischemia (gci) and reperfusion induced apoptosis that lead to cell injury and death. the bax and bcl-2 are pro-apoptotic and anti-apoptotic genes, respectively. these genes belong to the b-cell lymphoma-2 (bcl-2) family.in this study; we assessed the effect of pentoxifylline drug on bax/bcl2 gene dosage expression changes following ischemic reperfusion injury in kidney. in thi...
