Canagliflozin Inhibits Human Endothelial Cell Proliferation and Tube Formation
In conclusion, the present study identified canagliflozin as a potent inhibitor of human EC proliferation. The anti-proliferative action of canagliflozin is observed in ECs isolated from both the venous and arterial circulation, and is partly due to the blockade of cyclin A expression. In addition, this study found that canagliflozin inhibits tube formation in cultured ECs and mouse aortic rings. Notably, these actions are specific for canagliflozin and not seen with other SGLT2 inhibitors. The ability of canagliflozin to exert these pleiotropic effects on EC function may contribute to both the adverse and salutary actions...

OCT4B-190 protects against ischemic stroke by modulating GSK-3 β/HDAC6.
OCT4B-190 protects against ischemic stroke by modulating GSK-3β/HDAC6. Exp Neurol. 2019 Apr 11;: Authors: Chen Y, Wu Z, Zhu X, Zhang M, Zang X, Li X, Xu Y Abstract OCT4 is a key regulator in maintaining the pluripotency and self-renewal of embryonic stem cells (ESCs). Human OCT4 gene has three mRNA isoforms, termed OCT4A, OCT4B and OCT4B1. The 190-amino-acid protein isoform (OCT4B-190) is one of the major products of OCT4B mRNA, the biological function of which is still not well defined. Recent evidence suggests that OCT4B-190 may function in the cellular stress response. The glycogen synthase kinase...

Publication date: 9 April 2019Source: Cell Reports, Volume 27, Issue 2Author(s): Jianxiong Zeng, Yaoming Wang, Zhifei Luo, Lin-Chun Chang, Ji Seung Yoo, Huan Yan, Younho Choi, Xiaochun Xie, Benjamin E. Deverman, Viviana Gradinaru, Stephanie L. Gupton, Berislav V. Zlokovic, Zhen Zhao, Jae U. JungSummaryExcessive and unresolved neuroinflammation is a key component of the pathological cascade in brain injuries such as ischemic stroke. Here, we report that TRIM9, a brain-specific tripartite motif (TRIM) protein, was highly expressed in the peri-infarct areas shortly after ischemic insults in mice, but expression was decreased ...

Induction of Brain Arteriovenous Malformation Through CRISPR/Cas9-Mediated Somatic Alk1 Gene Mutations in Adult Mice
AbstractBrain arteriovenous malformation (bAVM) is an important risk factor for intracranial hemorrhage. The pathogenesis of bAVM has not been fully understood. Animal models are important tools for dissecting bAVM pathogenesis and testing new therapies. We have developed several mouse bAVM models using genetically modified mice. However, due to the body size, mouse bAVM models have some limitations. Recent studies identified somatic mutations in sporadic human bAVM. To develop a feasible tool to create sporadic bAVM in rodent and animals larger than rodent, we made tests using the CRISPR/Cas9 technique to induce somatic g...

Efficacy Evaluation of Liver-Directed Gene Therapy in Fabry Mice
Conclusions: Collectively, these data provide strong evidence that our liver-directed AAV-mediated gene therapy approach holds considerable therapeutic potential for the treatment of Fabry disease. We anticipate that a single dose IV procedure will pose minimal burden to Fabry patients and will be a viable alternative to biweekly enzyme infusions, potentially reducing treatment-related morbidity whislt improving patient quality of life and potentially providing them with a functional long-term cure.DisclosuresKia: Freeline: Employment, Equity Ownership.

MST1 Suppression Reduces Early Brain Injury by Inhibiting the NF- κB/MMP-9 Pathway after Subarachnoid Hemorrhage in Mice.
Conclusions: The current findings indicate that MST1 participates in SAH-induced BBB disruption and white matter fiber damage via the downstream NF-κB-MMP-9 signaling pathway. Therefore, MST1 antagonists may serve as a novel therapeutic target to prevent early brain injury in SAH patients. PMID: 30018671 [PubMed - in process]

Preservation of interhemispheric cortical connections through corpus callosum following intravenous infusion of mesenchymal stem cells in a rat model of cerebral infarction.
Abstract Systemic administration of mesenchymal stem cells (MSCs) following cerebral infarction exerts functional improvements. Previous research has suggested potential therapeutic mechanisms that promote neuroprotection and synaptogenesis. These include secretion of neurotrophic factors, remodeling of neural circuits, restoration of the blood brain barrier, reduction of inflammatory infiltration and demyelination, and elevation of trophic factors. In addition to these mechanisms, we hypothesized that restored interhemispheric bilateral motor cortex connectivity might be an additional mechanism of functional reco...

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...

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...

A Review of Mathematical Models for Muscular Dystrophy: A Systems Biology Approach
Discussion With new developments in computational power and data availability, a growing amount of research is using a systems biology approach to understand pathogenesis and progression of disease. Effective and integrated in vitro and in silico models could inform biological phenomena, even without the need of a living subject. For instance, over the last few decades, collagen hydrogel with muscle derived cells (CHMDCs) have promised to revolutionize in vitro experiments and tissue engineering. For CHMDCs to reach the envisioned use, verification by use of mathematical simulations are needed. Recently while examining sha...

Parvovirus B19 Infection in Children With Arterial Ischemic Stroke Brief Report
Conclusions—Using MassTag–polymerase chain reaction, we detected parvovirus B19—a virus known to infect erythrocytes and endothelial cells—in some cases of childhood arterial ischemic stroke. This approach can generate new, testable hypotheses about childhood stroke pathogenesis.

Experimental cardiac radiation exposure induces ventricular diastolic dysfunction with preserved ejection fraction
Breast cancer radiotherapy increases the risk of heart failure with preserved ejection fraction (HFpEF). Cardiomyocytes are highly radioresistant, but radiation specifically affects coronary microvascular endothelial cells, with subsequent microvascular inflammation and rarefaction. The effects of radiation on left ventricular (LV) diastolic function are poorly characterized. We hypothesized that cardiac radiation exposure may result in diastolic dysfunction without reduced EF. Global cardiac expression of the sodium-iodide symporter (NIS) was induced by cardiotropic gene (adeno-associated virus serotype 9) delivery to 5-w...

ADAMTS13 controls vascular remodeling by modifying VWF reactivity during stroke recovery
Angiogenic response is essential for ischemic brain repair. The von Willebrand factor (VWF)–cleaving protease disintegrin and metalloprotease with thrombospondin type I motif, member 13 (ADAMTS13) is required for endothelial tube formation in vitro, but there is currently no in vivo evidence supporting a function of ADAMTS13 in angiogenesis. Here we show that mice deficient in ADAMTS13 exhibited reduced neovascularization, brain capillary perfusion, pericyte and smooth muscle cell coverage on microvessels, expression of the tight junction and basement membrane proteins, and accelerated blood-brain barrier (BBB) break...
