Objective(s): Pioglitazone, an anti-diabetic agent, has been widely used to treat type II diabetes. However, the effect of pioglitazone on myocardial ischemia reperfusion injury (MIRI) is still unclear. Herein, the objective of this study is to learn about the regulation and mechanism of pioglitazone effects on oxygen glucose deprivation (OGD)-induced myocardial cell injury.Materials and Method...
Peroxisome proliferator-activated receptor gamma (PPARγ) is emerging as a major regulator in neurological diseases. However, the role of (PPARγ) and its co-regulators in cerebrovascular endothelial dysfunction after stroke is unclear. Here, we have demonstrated that (PPARγ) activation by pioglitazone significantly inhibited both oxygen-glucose deprivation-induced cerebral vascular endothelial c...
we investigated the effects of 25 mg-porphyrin-fullerene nanoparticles, ( 25 mgpmc16) smart ferroporphyrin nanoparticles, on pc12 cells exposed to oxygen-glucose deprivation/reperfusion. in order to explore its effect on cells under oxygen-glucose deprivation conditions, the cultures were pretreated with 25 mgpmc16 24 hours prior to oxygen-glucose deprivation/reperfusion. to initiate the oxygen...
the present study aims to investigate the effect of noscapine (0.5-2.5 µm), an alkaloid from the opium poppy, on primary murine fetal cortical neurons exposed to oxygen–glucose deprivation (ogd), an in vitro model of ischemia. cells were transferred to glucose-free dmem (dulbecco's modified eagle medium) and were exposed to hypoxia in a small anaerobic chamber. cell viability and nitric ox...
abstractin the present work we set out to investigate the neuroprotective effects of noscapine (0.5-2 µm) in presence of d-glucose on primary murine foetal cortical neurons after oxygen–glucose deprivation/24 hrs recovery. cell viability, nitric oxide production and intracellular calcium ([ca2+]i) levels were evaluated by mtt assay, the modified griess method and fura-2 respectively. 25 and 100...
background: oligodendrocytes, the myelinating glial cells of central nervous system, are highly vulnerable to ischemic‑induced excitotoxic insult, a phenomenon in which calcium overload triggers cell death. berberine is an alkaloid extracted from medicinal herbs as coptidis rhizoma with several pharmacological effects like inhibition of neuronal apoptosis in cerebral ischemia. methods: we exami...
Small ubiquitin-like modifier (SUMO)2/3 but not SUMO1 conjugation is activated after transient cerebral ischemia. To investigate its function, we blocked neuronal SUMO2/3 translation through lentiviral microRNA delivery in primary cortical neurons. Viability was unaffected by SUMO2/3 silencing unless neurons were stressed by transient oxygen-glucose deprivation (OGD). Both 15 and 45 minutes of ...
the protective effect of a l-type calcium channel blocker, nimodipine, on cell injury induced by oxygen-glucose deprivation (ogd) in pc12 cells was investigated. pc12 cells were exposed to in-vitro oxygen-glucose deprivation (30 minutes and 60 minutes respectively) in the presence or absence of nimodipine (10mm/l) in three different time schedules (pre-24h, pre-3h and concurrently). cellular vi...
The current study tested the potential neuroprotective function of Tanshinone IIA (ThIIA) in neuronal cells with oxygen-glucose deprivation (ODG) and re-oxygenation (OGDR). In SH-SY5Y neuronal cells and primary murine cortical neurons, ThIIA pre-treatment attenuated OGDR-induced viability reduction and apoptosis. Further, OGDR-induced mitochondrial depolarization, reactive oxygen species produc...
