Tat-NTS Suppresses the Proliferation, Migration and Invasion of Glioblastoma Cells by Inhibiting Annexin-A1 Nuclear Translocation
Cell Mol Neurobiol. 2021 Aug 3. doi: 10.1007/s10571-021-01134-y. Online ahead of print.ABSTRACTPrevention of the nuclear translocation of ANXA1 with Tat-NTS was recently reported to alleviate neuronal injury and protect against cerebral stroke. However, the role that Tat-NTS plays in the occurrence and development of gliomas still needs to be elucidated. Therefore, human glioblastoma (GB) cells were treated with various concentrations of Tat-NTS for 24 h, and cell proliferation, migration and invasion were assessed with CCK-8 and Transwell assays. The nuclear translocation of ANXA1 was evaluated by subcellular extraction a...

Orexin-A alleviates astrocytic apoptosis and inflammation via Inhibiting OX1R-mediated NF- κB and MAPK signaling pathways in cerebral ischemia/reperfusion injury
Biochim Biophys Acta Mol Basis Dis. 2021 Aug 3:166230. doi: 10.1016/j.bbadis.2021.166230. Online ahead of print.ABSTRACTOrexin-A (OXA) is a neuropeptide with neuroprotective effect by reducing cerebral ischemia/reperfusion injury (CIRI). Inflammation and apoptosis mediated by astrocyte activation are the key pathological mechanisms for CIRI. We thus attempted to confirm neuroprotective effects of OXA on astrocytic inflammation and apoptosis in CIRI and clarify the relative mechanisms. A middle cerebral artery occlusion and reperfusion (MCAO/R) rat model and U251 glioma cells model subjected to oxygen glucose deprivation an...

Safety of apixaban for venous thromboembolic primary prophylaxis in patients with newly diagnosed malignant glioma
In this study, we treated ten patients with newly diagnosed MG with apixaban, 2.5  mg twice daily beginning 2–21 days after craniotomy and continuing for up to 6 months. Unacceptable toxicity was defined by ≥ grade 2 CNS or non-CNS hemorrhage, a thromboembolic event (i.e. stroke) or cardiovascular event requiring anticoagulation or anti-platelet therapy. There were no unacc eptable toxicities to report and no treatment-related adverse events. None of the patients on the study were diagnosed with a VTE while receiving apixaban. We conclude that apixaban can be given safely to patients with primary MG shortly after cra...

The PROGRAM study: awake mapping versus asleep mapping versus no mapping for high-grade glioma resections: study protocol for an international multicenter prospective three-arm cohort study
This study is an international, multicenter, prospective three-arm cohort study of observational nature. Consecutive HGG patients will be operated with awake mapping, asleep mapping or no mapping with a 1:1:1 ratio. Primary endpoints are: (1) proportion of patients with National Institute of Health Stroke Scale deterioration at 6 weeks, 3 months and 6 months after surgery and (2) residual tumour volume of the contrast-enhancing and non-contrast-enhancing part as assessed by a neuroradiologist on postoperative contrast MRI scans. Secondary endpoints are: (1) overall survival and (2) progression-free survival at 12 months af...

Verbal and memory deficits caused by aphasic status epilepticus after resection of a left temporal lobe glioma
CONCLUSION: Prolonged ASE can induce verbal and memory deficits. Early intervention with intravenous anesthetics is required to obtain a favorable neurological prognosis.PMID:34992930 | PMC:PMC8720448 | DOI:10.25259/SNI_1120_2021

Cancers, Vol. 14, Pages 1207: Intercellular Communication in the Brain through Tunneling Nanotubes
Vignais Intercellular communication is essential for tissue homeostasis and function. Understanding how cells interact with each other is paramount, as crosstalk between cells is often dysregulated in diseases and can contribute to their progression. Cells communicate with each other through several modalities, including paracrine secretion and specialized structures ensuring physical contact between them. Among these intercellular specialized structures, tunneling nanotubes (TNTs) are now recognized as a means of cell-to-cell communication through the exchange of cellular cargo, controlled by a variety of biological t...

Eloquent Lower Grade Gliomas, a Highly Vulnerable Cohort: Assessment of Patients ’ Functional Outcome After Surgery Based on the LoG-Glio Registry
Majority of lower grade glioma (LGG) are located eloquently rendering surgical resection challenging. Aim of our study was to assess rate of permanent deficits and its predisposing risk factors. We retrieved 83 patients harboring an eloquently located LGGs from the prospective LoG-Glio Database. Patients without surgery or incomplete postoperative data were excluded. Sign rank test, explorative correlations by Spearman ρ and multivariable regression for new postoperative deficits were calculated. Eloquent region involved predominantly motor (45%) and language (40%). At first follow up after 3 months permanent neuro-logica...

Long Non Coding RNA Based Regulation of Cerebrovascular Endothelium
The rapid and high throughput discovery of long non coding RNAs (lncRNAs) has far outstripped the functional annotation of these novel transcripts in their respective cellular contexts. The cells of the blood brain barrier (BBB), especially the cerebrovascular endothelial cells (CVECs), are strictly regulated to maintain a controlled state of homeostasis for undisrupted brain function. Several key pathways are understood in CVEC function that lead to the development and maintenance of their barrier properties, the dysregulation of which leads to BBB breakdown and neuronal injury. Endothelial lncRNAs have been discovered an...
