Storax Protected Primary Cortical Neurons from Oxygen-Glucose Deprivation/Reoxygenation Injury via Inhibiting the TLR4/TRAF6/NF- κB Signaling Pathway
This study aimed to elucidate the neuroprotective effects and underlying mechanisms of storax on oxygen-glucose deprivation/reoxygenation (OGD/R) in injured cortical neurons. The cortical neurons of Wistar rats were primarily cultured in vitro. TheTUNELmethod and CM-H2DCFDA probe were used to detect cell apoptosis and reactive oxygen species (ROS) expression. Enzyme-linked immunosorbent assay, reverse transcription-polymerase chain reaction, and Western blot were used to detect the expression of inflammatory cytokines and proteins of the TLR4/TRAF6/NF-κB signaling pathway. Immunofluorescence was used to measure NF-κB nuc...

Silent information regulator 1 ameliorates oxidative stress injury via PGC-1 α/PPARγ-Nrf2 pathway after ischemic stroke in rat
CONCLUSION: Overall, our data indicated that SIRT1 directly mediated the PGC-1α/PPARγ pathway in response to focal cerebral ischemia/reperfusion-induced neurological deficit, providing insights into the treatment of focal cerebral ischemia/reperfusion injury.PMID:34774993 | DOI:10.1016/j.brainresbull.2021.11.001

Astrocytic cytochrome P450 4A/20-hydroxyeicosatetraenoic acid contributes to angiogenesis in the experimental ischemic stroke.
Abstract 20-Hydroxyeicosatetraenoic acid (20-HETE), a cytochrome P450 4A (CYP4A) metabolite of arachidonic acid, is one of the primary eicosanoids in most of microcirculatory beds. Studies have indicated that 20-HETE has important functions in the modulation of vascular tone, ion transport, inflammation reaction, and cellular proliferation. Both we and others have demonstrated that 20-HETE plays an important role in acute phase of ischemic stroke. However, little is known about the effect of 20-HETE on recovery phase of stroke. Crosstalk between the cells within the neurovascular unit is increasingly suspected of ...

Diallyl trisufide protects against oxygen glucose deprivation -induced apoptosis by scavenging free radicals via the PI3K/Akt -mediated Nrf2/HO-1 signaling pathway in B35 neural cells.
Abstract Oxidative stress contributes to development of ischemic brain damage. Many antioxidants have been proven effective in ameliorating cerebral ischemia injury by inhibiting oxidative stress. DATS, an organosulfuric component of garlic oil, exhibits antioxidative effects. In present study, we used OGD model to investigate the neuroprotective effects of DATS and the mechanisms related to these effects. B35 neural cells exposed to OGD caused a decrease in cell viability and increases in the percentage of apoptotic cells and the level of intracellular cleaved caspase-3, all of which were markedly attenuated by D...

Inhibition of thioredoxin-1 with siRNA exacerbates apoptosis by activating the ASK1-JNK/p38 pathway in brain of a stroke model rats.
Abstract Apoptosis is critical for the development of cerebral ischemia/reperfusion injury. Thioredoxin-1(Trx-1) protein has been reported to have anti-apoptotic effects in a variety of cell types, and it has been implicated in brain injury after middle cerebral artery occlusion (MCAO). Thus, we studied the effects of Trx1 silencing after MCAO in rats and examined whether inhibition of endogenous Trx1 could increase tissue levels of apoptosis. Male Sprague-Dawley rats (N=170) were subjected to 1h of middle cerebral arterial occlusion followed by 24h of reperfusion. Trx1 siRNAs were injected into rat brains 24h pri...

Upregulation of Hsp72 mediates anoxia/reoxygention neuroprotection in the freshwater turtle via modulation of ROS.
Abstract The neuroprotective role of Hsp72 has been demonstrated in several ischemic/stroke models to occur primarily through mediation of apoptotic pathways, and a number of heat shock proteins are upregulated in animal models capable of extended anoxic survival. In the present study, we investigated the role of Hsp72 on cell death and apoptotic regulators in one anoxia tolerant model system, the freshwater turtle Trachemys scripta. Since Hsp72 is known to regulate apoptosis through interactions with Bcl-2, we manipulated the levels of Hsp72 and Bcl-2 with siRNA in neuronally enriched primary cell cultures and ex...

Activation of STAT3 is involved in neuroprotection by electroacupuncture pretreatment via cannabinoid CB1 receptors in rats.
In conclusion, EA pretreatment enhances STAT3 activation via CB1R to protect against cerebral ischemia, suggesting that STAT3 activation may be a novel target for stroke intervention. PMID: 23880371 [PubMed - as supplied by publisher]
