Previous studies have demonstrated that pretreatment with electroacupuncture (EA) elicits rapid tolerance to focal cerebral ischemia and that Wnt/β-catenin plays an essential role in cell survival and proliferation. In the present study, we investigated the role of Wnt/β-catenin in EA pretreatment-induced neuroprotection. Two hours after EA pretreatment, focal cerebral ischemia was induced by m...
Caspase-9 is critical for cytochrome c (cyto-c)-dependent apoptosis and normal brain development. We determined that this apical protease in the cyto-c pathway for apoptosis resides inside mitochondria in several types of cells, including cardiomyocytes and many neurons. Caspase-9 is released from isolated mitochondria on treatment with Ca2+ or Bax, stimuli implicated in ischemic neuronal cell ...
Perinatal hypoxia-ischemia is a major cause of acute mortality in newborns and cognitive and motor impairments in children. Cerebral hypoxia-ischemia leads to excitotoxicity and necrotic and apoptotic cell death, in which mitochondria play a major role. Increased resistance against major damage can be achieved by preconditioning triggered by subtle insults. CO, a toxic molecule that is also gen...
The present study aimed to investigate the effects of the phosphoinositide 3‑kinase (PI3K)/Akt signaling pathway on the Wnt/β‑catenin signaling pathway in rats with focal cerebral ischemia‑reperfusion injury. A total of 96 rat focal cerebral ischemia‑reperfusion models, established according to a modified version of Longa's method, were randomly divided into four groups: Sham‑operated (S), cere...
Introduction: Oxidative stress plays a crucial role in the impairment of synaptic plasticity following cerebral ischemia which ultimately results in memory dysfunction. Hence, application of antioxidant agents could be beneficial in the management of memory deficit after brain ischemia. Minocycline is a tetracycline antibiotic with antioxidant effect. The main objective of this work was to asse...
Introduction: Stroke is a neurological disease and one of the leading causes of death all over the world. It is also an important cause of disability in people over age over 65. It may be possible to reduce the incidence of cerebral ischemia using antioxidants, followed by inhibition of oxidative and inflammatory mechanisms. Troxerutin is a natural bioflavonoid with antioxidant and anti-inflamm...
