Neuron-specific SUMO knockdown suppresses global gene expression response and worsens functional outcome after transient forebrain ischemia in mice.
(Neuroscience, 2017-02)Small ubiquitin-like modifier (SUMO) conjugation (SUMOylation) plays key roles in neurologic function in health and disease. Neuronal SUMOylation is essential for emotionality and cognition, and this pathway is dramatically ... -
Neuronal IL-4Rα modulates neuronal apoptosis and cell viability during the acute phases of cerebral ischemia.
(The FEBS journal, 2018-08)Ischemic stroke caused by an embolus or local thrombosis results in neural tissue damage (an infarct) in the territory of the occluded cerebral artery. Decades of studies have increased our understanding of the molecular ... -
Neuroprotective efficacy from a lipophilic redox-modulating Mn(III) N-Hexylpyridylporphyrin, MnTnHex-2-PyP: rodent models of ischemic stroke and subarachnoid hemorrhage.
(The Journal of pharmacology and experimental therapeutics, 2011-09)Intracerebroventricular treatment with redox-regulating Mn(III) N-hexylpyridylporphyrin (MnPorphyrin) is remarkably efficacious in experimental central nervous system (CNS) injury. Clinical development has been arrested ... -
O-linked β-N-acetylglucosamine modification of proteins is activated in post-ischemic brains of young but not aged mice: Implications for impaired functional recovery from ischemic stress.
(Journal of cerebral blood flow and metabolism : official journal of the International Society of Cerebral Blood Flow and Metabolism, 2016-02)To evaluate the effect of age on the response of brains to an ischemic challenge, we subjected young and aged mice to transient forebrain ischemia, and analyzed the heat shock response and unfolded protein response, ubiquitin ... -
Perception Versus Actual Performance in Timely Tissue Plasminogen Activation Administration in the Management of Acute Ischemic Stroke.
(J Am Heart Assoc, 2015-07-22)BACKGROUND: Timely thrombolytic therapy can improve stroke outcomes. Nevertheless, the ability of US hospitals to meet guidelines for intravenous tissue plasminogen activator (tPA) remains suboptimal. What is unclear is ... -
PERK (Protein Kinase RNA-Like ER Kinase) Branch of the Unfolded Protein Response Confers Neuroprotection in Ischemic Stroke by Suppressing Protein Synthesis.
(Stroke, 2020-05)Background and Purpose- Ischemic stroke impairs endoplasmic reticulum (ER) function, causes ER stress, and activates the unfolded protein response. The unfolded protein response consists of 3 branches controlled by ER stress ... -
Post-ischemia common carotid artery occlusion worsens memory loss, but not sensorimotor deficits, in long-term survived stroke mice.
(Brain research bulletin, 2022-06)Ischemic stroke in rodents is usually induced by intraluminal occlusion of the middle cerebral artery (MCA) via the external carotid artery (ECA) or the common carotid artery (CCA). The latter route requires permanent CCA ... -
Relationship between hospital performance measures and outcomes in patients with acute ischaemic stroke: a prospective cohort study.
(BMJ open, 2018-08)OBJECTIVE:Evidence-based performance measures have been increasingly used to evaluate hospital quality of stroke care, but their impact on stroke outcomes has not been verified. We aimed to evaluate the correlations between ... -
Renal Dysfunction and In-Hospital Outcomes in Patients With Acute Ischemic Stroke After Intravenous Thrombolytic Therapy.
(Journal of the American Heart Association, 2019-10-09)Background The impact of estimated glomerular filtration rate (eGFR) on clinical short-term outcomes after stroke thrombolysis with tissue plasminogen activator remains controversial. Methods and Results We analyzed 18 320 ... -
Risks and Benefits Associated With Prestroke Antiplatelet Therapy Among Patients With Acute Ischemic Stroke Treated With Intravenous Tissue Plasminogen Activator.
(JAMA neurology, 2016-01)Intravenous tissue plasminogen activator (tPA) is known to improve outcomes in ischemic stroke; however, many patients may have been receiving antiplatelet therapy before acute ischemic stroke and could face an increased ... -
Risks of intracranial hemorrhage among patients with acute ischemic stroke receiving warfarin and treated with intravenous tissue plasminogen activator.
(JAMA, 2012-06)Intravenous tissue plasminogen activator (tPA) is known to improve outcomes in ischemic stroke; however, patients receiving long-term chronic warfarin therapy may face an increased risk for intracranial hemorrhage when treated ... -
Small ubiquitin-like modifier 3-modified proteome regulated by brain ischemia in novel small ubiquitin-like modifier transgenic mice: putative protective proteins/pathways.
(Stroke, 2014-04)<h4>Background and purpose</h4>Small ubiquitin-like modifier (SUMO) conjugation is a post-translational modification associated with many human diseases. Characterization of the SUMO-modified proteome is pivotal to define ... -
Targeting the SUMO pathway for neuroprotection in brain ischaemia.
(Stroke and vascular neurology, 2016-09)Small ubiquitin-like modifier (SUMO) conjugation (SUMOylation) is a post-translational protein modification that modulates almost all major cellular processes, and has been implicated in many human diseases. A growing body ... -
Thrombolysis in young adults with stroke: Findings from Get With The Guidelines-Stroke.
(Neurology, 2019-06)OBJECTIVE:To determine whether young adults (≤40 years old) with acute ischemic stroke are less likely to receive IV tissue plasminogen activator (tPA) and more likely to have longer times to brain imaging and treatment. ... -
XBP1 (X-Box-Binding Protein-1)-Dependent O-GlcNAcylation Is Neuroprotective in Ischemic Stroke in Young Mice and Its Impairment in Aged Mice Is Rescued by Thiamet-G.
(Stroke, 2017-06)<h4>Background and purpose</h4>Impaired protein homeostasis induced by endoplasmic reticulum dysfunction is a key feature of a variety of age-related brain diseases including stroke. To restore endoplasmic reticulum function ...
