CircFOXP1 alleviates brain injury after acute ischemic stroke by regulating STAT3/apoptotic signaling
Transl Res. 2023 Feb 12:S1931-5244(23)00022-1. doi: 10.1016/j.trsl.2023.01.007. Online ahead of print.ABSTRACTAccording to previous studies, circular RNAs (circRNAs) are involved in multiple pathological processes of acute ischemic stroke (AIS). However, the relationship between circFOXP1 and IS has not yet been reported. Here, we found that circFOXP1 expression was significantly decreased in the peripheral blood of AIS patients compared to controls and was associated with the severity and prognosis of AIS. Functionally, knockdown and overexpression of circFOXP1 promoted and inhibited apoptotic signaling, respectively, fol...

Perilipin 5 protects against oxygen-glucose deprivation/reoxygenation-elicited neuronal damage by inhibiting oxidative stress and inflammatory injury via the Akt-GSK-3 β-Nrf2 pathway
CONCLUSIONS: Plin5 confers neuroprotection for neurons against OGD/R damage via effects on the Nrf2-Akt-GSK-3β pathway. This work indicates a possible role of Plin5 in cerebral ischemic stroke and the up-regulation of Plin5 is a sort of survival strategy for neurons suffering from ischemic injury.PMID:35367744 | DOI:10.1016/j.intimp.2022.108718

HIF ‑1α attenuates neuronal apoptosis by upregulating EPO expression following cerebral ischemia‑reperfusion injury in a rat MCAO model.
HIF‑1α attenuates neuronal apoptosis by upregulating EPO expression following cerebral ischemia‑reperfusion injury in a rat MCAO model. Int J Mol Med. 2020 Jan 28;: Authors: Li J, Tao T, Xu J, Liu Z, Zou Z, Jin M Abstract Hypoxia‑inducible factor‑1α (HIF‑1α) is a key transcriptional factor in response to hypoxia and is involved in ischemic stroke. In the present study, the potential for HIF‑1α to inhibit neuronal apoptosis through upregulating erythropoietin (EPO) was investigated in a transient middle cerebral artery occlusion (tMCAO) rat stroke model. For this purpose, a recombinant ...

Overexpression of Adiponectin Improves Neurobehavioral Outcomes After Focal Cerebral Ischemia in Aged Mice.
CONCLUSIONS: Our results demonstrate that APN overexpression reduces ischemic brain injury and improves neurobehavioral function recovery in aged mice than in young mice, suggesting APN is more beneficial in aged animals after ischemic stroke. PMID: 24164711 [PubMed - as supplied by publisher]

LRG1 Promotes Apoptosis and Autophagy through the TGFβ-smad1/5 Signaling Pathway to Exacerbate Ischemia/Reperfusion Injury
In this study, we discussed the function and mechanism of LRG1 in acute ischemic stroke from both basic and clinical research points of view. Mice underwent transient middle cerebral artery occlusion (tMCAO) surgery two weeks after LRG1 was overexpressed by the delivery of adeno-associated virus (AAV). For wild-type mice, both the protein and the transcript of LRG1 in the brain tissue were elevated after tMCAO. Meanwhile, the serum levels of LRG1 were decreased after tMCAO. The neuronal injury was shown aggravated in the AAV-LRG1 group (AAV-LRG1 mice with tMCAO) through infarction volume, neurological score, HE, and Nissl ...

Changes in Levels of Hypoxia-Induced Mediators in Rat Hippocampus During Chronic Cerebral Hypoperfusion.
Abstract The hypoxia-inducible factor (HIF)-mediated signaling pathway is an adaptive and protective mechanism that is triggered by hypoxia, ischemia, and other pathophysiological conditions. The expression of HIF-1α and downstream genes, some of which are pro-apoptotic whereas others are pro-survival, is up-regulated in ischemic stroke. Interestingly, however, the effects of HIF-1α activation are different in the early and late stages of acute cerebral ischemia, and these differences may depend on the duration and severity of hypoxia. Therefore, in the present study, we investigated the effect of HIF-1α activa...

Stem Cell Factor Gene Transfer Improves Cardiac Function After Myocardial Infarction in Swine Original Articles
Conclusions— Local overexpression of SCF post-MI induces the recruitment of c-kit+ cells at the infarct border area acutely. In the chronic stages, SCF gene transfer was associated with improved cardiac function in a preclinical model of ischemic cardiomyopathy.

Adenoviruses-mediated RNA interference targeting cytosolic phospholipase A2 α attenuates focal ischemic brain damage in mice.
Adenoviruses-mediated RNA interference targeting cytosolic phospholipase A2α attenuates focal ischemic brain damage in mice. Mol Med Rep. 2018 Feb 15;: Authors: Wu H, Liu H, Zuo F, Zhang L Abstract Cerebral ischemia injury is a clinical, frequently occurring disease, which causes a heavy burden on society and families. It has been demonstrated that cytosolic phospholipase A2α (cPLA2α) is significant in neurological injury caused by ischemic brain injury, and inhibition of cPLA2α may reduce stroke injury. In the present study, the role of cPLA2α was investigated in a mouse model of middle cerebral...

Neuroscience is the Next Oncology
by Michael D. Ehlers, MD, PhD Dr. Ehlers is with Biogen in Cambridge, Massachusetts. Innov Clin Neurosci. 2018;15(3–4):15–16 Funding: No funding was received for the preparation of this article. Disclosures: Dr. Ehlers is an employee and shareholder at Biogen Inc. in Cambridge, Massachusetts. Prominent and expensive failures in Alzheimer’s disease therapies have led to a contagious belief system in some parts of the biopharma industry that neuroscience is just too hard, too risky, and too uncertain. But, might this belief system itself be a residual bias of the past? Close inspection reveals all the signs of a coming...
