Isoquercitrin Upregulates Aldolase C Through Nrf2 to Ameliorate OGD/R-Induced Damage in SH-SY5Y Cells.

Isoquercitrin (ISO), an extract from Chinese traditional herb, exhibits potent neuroprotective roles in various disease models. However, its role in stroke is not fully understood. We established oxygen-glucose deprivation and reoxygenation (OGD/R) model in SH-SY5Y cell to study the roles of ISO in stroke.

Black Bamboo Rhizome Extract Improves Cognitive Dysfunction by Upregulating the Expression of Hippocampal BDNF and CREB in Rats with Cerebral Ischaemia-Reperfusion Injury.

Introduction: The study aimed to explore the effects of treatment with black bamboo rhizome extracts on learning and memory and determine the underlying mechanisms in rats with cerebral ischaemia-reperfusion injury.

Methods: Sprague-Dawley rats were randomly divided into the following four groups: control, middle cerebral artery occlusion (MCAO), low-dose drug, and high-dose drug groups. Rats underwent MCAO using a suture method before drug treatment.

Neuroprotection by 2,3,5,4'-tetrahydroxystilbene-2-O-β-D-glucoside extracts from against cerebral ischemia/reperfusion injury through the 5-hydroxytryptamine/5-hydroxytryptamine receptor pathway.

To investigate the therapeutic effect of 2,3,5,4'-tetrahydroxystilbene-2-O-β-D-glucoside (TSG) on the expression of 5-hydroxytryptamine (5-HT)/5-HT receptor 2A (5-HT2A), 5-HT transporter (5-HTT), and uncoupling protein 4 (UCP4) after cerebral ischemia/reperfusion (I/R) injury. Sprague-Dawley rats were randomly divided into control, model and 125 (low-dose), 250 (middle-dose), and 500 (high-dose) mg/mL TSG groups. Rat cerebral I/R injury model was established by middle cerebral artery occlusion (MCAO).
