Novel mechanistic insight on the neuroprotective effect of berberine: The role of PPAR δ for antioxidant action
Free Radic Biol Med. 2022 Jan 27:S0891-5849(22)00033-8. doi: 10.1016/j.freeradbiomed.2022.01.022. Online ahead of print.ABSTRACTCerebral ischemic stroke ranks the second leading cause of death and the third leading cause of disability in lifetime all around the world, urgently necessitating effective therapeutic interventions. Reactive oxygen species (ROS) have been implicated in stroke pathogenesis and peroxisome proliferator-activated receptors (PPARs) are prominent targets for ROS management. Although recent research has shown antioxidant effect of berberine (BBR), little is known regarding its effect upon ROS-PPARs sig...

Impact of UCP2 depletion on heat stroke-induced mitochondrial function in human umbilical vein endothelial cells
CONCLUSION: Our results indicate that UCP2 protects against HS-induced vascular endothelial damage and that it enhances mitochondrial function. These findings reveal that UCP2 can be a potential contributor to mechanism-based therapeutic strategies for HS.PMID:35129048 | DOI:10.1080/02656736.2022.2032846

The Mfn1- βIIPKC Interaction Regulates Mitochondrial Dysfunction via Sirt3 Following Experimental Subarachnoid Hemorrhage
AbstractNeuronal injury following subarachnoid hemorrhage (SAH) has been shown to be associated with mitochondrial dysfunction and oxidative stress. βIIPKC, a subtype of protein kinase C (PKC), accumulates on the mitochondrial outer membrane and phosphorylates mitofusin 1 (Mfn1) at serine 86. Here, we investigated the role of Mfn1-βIIPKC interaction in brain damage and neurological function in both in vivo and in vitro experimental SAH models. The expression of βIIPKC protein and the interaction of Mfn1-βIIPKC were found to be increased after OxyHb treatment in primary cultured cortical neurons and were also observed i...

Isoflurane and Netrin-1 combination therapy enhances angiogenesis and neurological recovery by improving the expression of HIF-1 α-Netrin-1-UNC5B/VEGF cascade to attenuate cerebral ischemia injury
In conclusion, our results suggested that ISO combined with NT-1 could promote angiogenesis, recover long-term neurobehavioral function, and attenuate cerebral ischemia injury by activating the HIF-1α-Netrin-1-UNC5B/VEGF cascade.PMID:35247371 | DOI:10.1016/j.expneurol.2022.114028

DL-3-n-butylphthalide prevents oxidative stress and atherosclerosis by targeting Keap-1 and inhibiting Keap-1/Nrf-2 interaction
Eur J Pharm Sci. 2022 Mar 5:106164. doi: 10.1016/j.ejps.2022.106164. Online ahead of print.ABSTRACTAtherosclerosis is the common pathophysiological foundation of ischaemic stroke and myocardial ischaemia. Oxidative stress is intricately related to the progress of atherosclerosis. DL-3-n-butylphthalide (NBP) is a synthesized raceme of L-3-n-butylphthalide that is first isolated from celery. As a neuroprotective agent, NBP also exhibits potent antioxidative activity. Our research aimed to evaluate the effect of NBP on atherosclerosis and to explore the underlying antioxidative mechanisms and targets. Firstly, we detected the...

Acute Administration of Metformin Protects Against Neuronal Apoptosis Induced by Cerebral Ischemia-Reperfusion Injury via Regulation of the AMPK/CREB/BDNF Pathway
Metformin is a first-line anti-diabetic agent with a powerful hypoglycemic effect. Several studies have reported that metformin can improve the prognosis of stroke patients and that this effect is independent of its hypoglycemic effect; however, the specific mechanism remains unclear. In this research, we explored the effect and specific mechanism of metformin in cerebral ischemia-reperfusion (I/R) injury by constructing a transient middle cerebral artery occlusion model in vivo and a glucose and oxygen deprivation/reoxygenation (OGD/R) model in vitro. The results of the in vivo experiments showed that acute treatment with...

Non-mitogenic fibroblast growth factor 1 protects against ischemic stroke by regulating microglia/macrophage polarization through Nrf2 and NF- κB pathways
Neuropharmacology. 2022 Apr 19:109064. doi: 10.1016/j.neuropharm.2022.109064. Online ahead of print.ABSTRACTMicroglia are immune cells in the central nervous system (CNS) that participate in response to pathological process after ischemic injury. Non-mitogenic fibroblast growth factor 1 (nmFGF1) is an effective neuroprotective factor that is also known as a metabolic regulator. The present study aimed to investigate the effects and mechanism of the neuroprotective ability of nmFGF1 on microglia in mice after photothrombosis (PT) stroke model, to determine whether it could ameliorate ischemic injury in stroke experiment. We...
