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 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 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 simple technique for augmentation of axonal ingrowth into chondroitinase-treated acellular nerve grafts using nerve growth factor.
(Annals of plastic surgery, 2012-05)<h4>Background and purpose</h4>Improvement in axonal regeneration may lead to the development of longer nerve grafts and improved outcomes for patients with peripheral nerve injury. Although the use of acellular nerve grafts ... -
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 ... -
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 ... -
Bladder fibrosis during outlet obstruction is triggered through the NLRP3 inflammasome and the production of IL-1β.
(American journal of physiology. Renal physiology, 2017-09)Bladder outlet obstruction (BOO) triggers inflammation in the bladder through the NLRP3 inflammasome. BOO also activates fibrosis, which is largely responsible for the decompensation of the bladder in the chronic state. ... -
Bone Marrow Mesenchymal Stem Cell Transplantation Increases GAP-43 Expression via ERK1/2 and PI3K/Akt Pathways in Intracerebral Hemorrhage.
(Cellular physiology and biochemistry : international journal of experimental cellular physiology, biochemistry, and pharmacology, 2017-01)<h4>Background/aims</h4>Intracerebral hemorrhage (ICH) occurs in hypertensive patients and results in high rates of mortality and disability. This study determined whether bone marrow mesenchymal stem cell (BMSC) transplantation ... -
Brief Glutamine Pretreatment Increases Alveolar Macrophage CD163/Heme Oxygenase-1/p38-MAPK Dephosphorylation Pathway and Decreases Capillary Damage but Not Neutrophil Recruitment in IL-1/LPS-Insufflated Rats.
(PLoS One, 2015)BACKGROUND: Glutamine (GLN) attenuates acute lung injury (ALI) but its effect on alveolar macrophages is unknown. We hypothesized that GLN pretreatment would induce the anti-inflammatory CD163/heme oxygenase (HO)-1/p38-MAPK ... -
Cannabis use is associated with potentially heritable widespread changes in autism candidate gene DLGAP2 DNA methylation in sperm.
(Epigenetics, 2020-01)Parental cannabis use has been associated with adverse neurodevelopmental outcomes in offspring, but how such phenotypes are transmitted is largely unknown. Using reduced representation bisulphite sequencing (RRBS), we recently ... -
Cell type-specific changes in retinal ganglion cell function induced by rod death and cone reorganization in rats.
(Journal of neurophysiology, 2017-07)We have determined the impact of rod death and cone reorganization on the spatiotemporal receptive fields (RFs) and spontaneous activity of distinct retinal ganglion cell (RGC) types. We compared RGC function between healthy ... -
Characterization of porous, dexamethasone-releasing polyurethane coatings for glucose sensors.
(Acta Biomaterialia, 2014-11)Commercially available implantable needle-type glucose sensors for diabetes management are robust analytically but can be unreliable clinically primarily due to tissue-sensor interactions. Here, we present the physical, ... -
Curcumin Ameliorates Heat-Induced Injury through NADPH Oxidase-Dependent Redox Signaling and Mitochondrial Preservation in C2C12 Myoblasts and Mouse Skeletal Muscle.
(The Journal of nutrition, 2020-09)<h4>Background</h4>Nicotinamide adenine dinucleotide phosphate (NADPH) oxidase and the mitochondrial electron transport chain are the primary sources of reactive oxygen species (ROS). Previous studies have shown that severe ... -
Early propranolol treatment induces lung heme-oxygenase-1, attenuates metabolic dysfunction, and improves survival following experimental sepsis.
(Crit Care, 2013-09-10)INTRODUCTION: Pharmacological agents that block beta-adrenergic receptors have been associated with improved outcome in burn injury. It has been hypothesized that injuries leading to a hypermetabolic state, such as septic ... -
Effects of striatal nitric oxide production on regional cerebral blood flow and seizure development in rats exposed to extreme hyperoxia.
(Journal of applied physiology (Bethesda, Md. : 1985), 2015-12)The endogenous vasodilator and signaling molecule nitric oxide has been implicated in cerebral hyperemia, sympathoexcitation, and seizures induced by hyperbaric oxygen (HBO2) at or above 3 atmospheres absolute (ATA). It ... -
Folate regulation of axonal regeneration in the rodent central nervous system through DNA methylation.
(J Clin Invest, 2010-05)The folate pathway plays a crucial role in the regeneration and repair of the adult CNS after injury. Here, we have shown in rodents that such repair occurs at least in part through DNA methylation. In animals with combined ... -
Hyaluronic Acid Hydrogel Integrated with Mesenchymal Stem Cell-Secretome to Treat Endometrial Injury in a Rat Model of Asherman's Syndrome.
(Advanced healthcare materials, 2019-07)Stem cell therapies have made strides toward the efficacious treatment of injured endometrium and the prevention of intrauterine adhesions, or Asherman's syndrome (AS). Despite this progress, they are limited by their risk ... -
Increased renal dopamine and acute renal adaptation to a high-phosphate diet.
(American journal of physiology. Renal physiology, 2011-05)The current experiments explore the role of dopamine in facilitating the acute increase in renal phosphate excretion in response to a high-phosphate diet. Compared with a low-phosphate (0.1%) diet for 24 h, mice ... -
