A beta-adrenergic receptor kinase-like enzyme is involved in olfactory signal termination.
(Proc Natl Acad Sci U S A, 1993-02-15)We have previously shown that second-messenger-dependent kinases (cAMP-dependent kinase, protein kinase C) in the olfactory system are essential in terminating second-messenger signaling in response to odorants. We now document ... -
A blinded randomized assessment of laser Doppler flowmetry efficacy in standardizing outcome from intraluminal filament MCAO in the rat.
(Journal of neuroscience methods, 2015-02)<h4>Background</h4>Laser Doppler flowmetry (LDF) is widely used for estimating cerebral blood flow changes during intraluminal middle cerebral artery occlusion (MCAO). No investigation has systematically examined LDF efficacy ... -
A membrane-associated progesterone-binding protein, 25-Dx, is regulated by progesterone in brain regions involved in female reproductive behaviors.
(Proc Natl Acad Sci U S A, 2000-11-07)The ventromedial hypothalamus (VMH) plays a central role in the regulation of the female reproductive behavior lordosis, a behavior dependent upon the sequential activation of receptors for the ovarian steroid hormones estradiol ... -
A model of sequential heart and composite tissue allotransplant in rats.
(Plast Reconstr Surg, 2010-07)BACKGROUND: Some of the 600,000 patients with solid organ allotransplants need reconstruction with a composite tissue allotransplant, such as the hand, abdominal wall, or face. The aim of this study was to develop a rat ... -
A Peptide Uncoupling BDNF Receptor TrkB from Phospholipase Cγ1 Prevents Epilepsy Induced by Status Epilepticus.
(Neuron, 2015-11-04)The BDNF receptor tyrosine kinase, TrkB, underlies nervous system function in both health and disease. Excessive activation of TrkB caused by status epilepticus promotes development of temporal lobe epilepsy (TLE), revealing ... -
A selective inhibitor of eIF2alpha dephosphorylation protects cells from ER stress.
(Science (New York, N.Y.), 2005-02)Most protein phosphatases have little intrinsic substrate specificity, making selective pharmacological inhibition of specific dephosphorylation reactions a challenging problem. In a screen for small molecules that protect ... -
A wireless multi-channel recording system for freely behaving mice and rats.
(PLoS One, 2011)To understand the neural basis of behavior, it is necessary to record brain activity in freely moving animals. Advances in implantable multi-electrode array technology have enabled researchers to record the activity of neuronal ... -
Acetylcholine Modulates Cerebellar Granule Cell Spiking by Regulating the Balance of Synaptic Excitation and Inhibition.
(The Journal of neuroscience : the official journal of the Society for Neuroscience, 2020-04)Sensorimotor integration in the cerebellum is essential for refining motor output, and the first stage of this processing occurs in the granule cell layer. Recent evidence suggests that granule cell layer synaptic integration ... -
Altered diffusion tensor imaging measurements in aged transgenic Huntington disease rats.
(Brain Struct Funct, 2013-05)Rodent models of Huntington disease (HD) are valuable tools for investigating HD pathophysiology and evaluating new therapeutic approaches. Non-invasive characterization of HD-related phenotype changes is important for monitoring ... -
An immunoglobulin C kappa-reactive single chain antibody fusion protein induces tolerance through receptor editing in a normal polyclonal immune system.
(J Exp Med, 2005-03-07)Understanding immune tolerance mechanisms is a major goal of immunology research, but mechanistic studies have generally required the use of mouse models carrying untargeted or targeted antigen receptor transgenes, which ... -
An off-the-shelf artificial cardiac patch improves cardiac repair after myocardial infarction in rats and pigs.
(Science translational medicine, 2020-04)Cell therapy has been a promising strategy for cardiac repair after injury or infarction; however, low retention and engraftment of transplanted cells limit potential therapeutic efficacy. Seeding scaffold material with ... -
Anti-hypotensive treatment and endothelin blockade synergistically antagonize exercise fatigue in rats under simulated high altitude.
(PLoS One, 2014)Rapid ascent to high altitude causes illness and fatigue, and there is a demand for effective acute treatments to alleviate such effects. We hypothesized that increased oxygen delivery to the tissue using a combination of ... -
ApoE mimetic ameliorates motor deficit and tissue damage in rat spinal cord injury.
(Journal of neuroscience research, 2014-07)Apolipoprotein E (apoE), a plasma protein responsible for transporting lipid and cholesterol, modulates responses of the central nervous system to injury. Small peptides derived from the receptor-binding region of apoE can ... -
Aprotinin improves functional outcome but not cerebral infarct size in an experimental model of stroke during cardiopulmonary bypass.
(Anesthesia and analgesia, 2010-07)<h4>Background</h4>Aprotinin, a nonspecific serine protease inhibitor, has been used to decrease bleeding and reduce the systemic inflammatory response after cardiopulmonary bypass (CPB). Studies have variably linked aprotinin ... -
ARFGAP1 promotes the formation of COPI vesicles, suggesting function as a component of the coat.
(J Cell Biol, 2002-10-14)The role of GTPase-activating protein (GAP) that deactivates ADP-ribosylation factor 1 (ARF1) during the formation of coat protein I (COPI) vesicles has been unclear. GAP is originally thought to antagonize vesicle formation ... -
Argon Inhalation for 24 Hours After Onset of Permanent Focal Cerebral Ischemia in Rats Provides Neuroprotection and Improves Neurologic Outcome.
(Critical care medicine, 2019-08)<h4>Objectives</h4>We tested the hypothesis that prolonged inhalation of 70% argon for 24 hours after in vivo permanent or temporary stroke provides neuroprotection and improves neurologic outcome and overall recovery after ... -
Association between cell-mediated demyelination and astrocyte stimulation.

Baroreceptor afferents modulate brain excitation and influence susceptibility to toxic effects of hyperbaric oxygen.
(Journal of applied physiology (Bethesda, Md. : 1985), 2014-09)Unexplained adjustments in baroreflex sensitivity occur in conjunction with exposures to potentially toxic levels of hyperbaric oxygen. To investigate this, we monitored central nervous system, autonomic and cardiovascular ... -
Bbeta-adrenergic receptor kinase-1 levels in catecholamine-induced myocardial hypertrophy: regulation by beta- but not alpha1-adrenergic stimulation.
(Hypertension, 1999-01)Pressure overload ventricular hypertrophy is accompanied by dysfunctional beta-adrenergic receptor signaling due to increased levels of the beta-adrenergic receptor kinase-1, which phosphorylates and desensitizes beta-adrenergic ... -
beta-arrestin-1 competitively inhibits insulin-induced ubiquitination and degradation of insulin receptor substrate 1.
