Comparison of vascular growth factors in the murine brain reveals placenta growth factor as prime candidate for CNS revascularization
Vascular bypass procedures in the central nervous system (CNS) remain technically challenging, hindered by complications and often failing to prevent adverse outcome such as stroke. Thus, there is an unmet clinical need for a safe and effective CNS revascularization. Vascular endothelial growth factors (VEGFs) are promising candidates for revascularization; however, their effects appear to be tissue-specific and their potential in the CNS has not been fully explored. To test growth factors for angiogenesis in the CNS, we characterized the effects of endothelium-specific growth factors on the brain vasculature and parenchym...

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...

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...

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...

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]

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.

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...

Therapeutic potential of AAV9-S15D-RLC gene delivery in humanized MYL2 mouse model of HCM
This study is focused on aspartic acid-to-valine (D166V) mutation in the myosin regulatory light chain, RLC (MYL2 gene), associated with a malignant form of HCM. Since myosin RLC phosphorylation is critical for normal cardiac function, we aimed to exploit this post-translational modification via phosphomimetic-RLC gene therapy. We hypothesized that mimicking/modulating cardiac RLC phosphorylation in non-phosphorylatable D166V myocardium would improve heart function of HCM-D166V mice. Adeno-associated virus, serotype-9 (AAV9) was used to deliver phosphomimetic human RLC variant with serine-to-aspartic acid substitution at S...

Effects of GDNF-Transfected Marrow Stromal Cells on Rats with Intracerebral Hemorrhage
Objective: The present study aimed to investigate the effects of Mesenchymal stem cells/glial cell line derived neurotrophic factor (MSCs/GDNF) transplantation on nerve reconstruction in rats with intracerebral hemorrhage. Methods: GDNF transduction to MSCs was using adenovirus vector pAdEasy-1-pAdTrack-CMV prepared. Intracerebral hemorrhage (ICH) was induced by injection of collagenase and heparin into the caudate putamen. At the third day after a collagenase-induced ICH, adult male SD rats were randomly divided into saline group, MSCs group and MSCs/GDNF group.
