Indomethacin and salicylate decrease epinephrine-induced glycogenolysis

Metabolism: Clinical and Experimental
J D MillerM A Sperling

Abstract

Epinephrine (E) produces an immediate (0-30 minutes) rise in hepatic glucose production (Ra), largely due to activation of glycogenolysis; thereafter, E-stimulated gluconeogenesis becomes the major factor maintaining glucose production. To investigate the possible role of arachidonic acid metabolites on Ra during E stimulation, we infused E in trained conscious dogs before and during administration of two inhibitors of arachidonic acid metabolism, indomethacin (INDO) and salicylate (S). On separate days, experimental animals were treated with both oral and IV INDO and oral acetylsalicylic acid and IV sodium salicylate. Ra and glucose utilization (Rd), both in mg x kg-1 min-1, were calculated by isotope dilution using 3-3H-glucose. After achieving steady state specific activity, control (C) and experimental animals (n = 6 per group) received E (0.1 ug x kg-1 min-1) for 150 minutes, raising plasma levels to approximately 1500 pg/mL in each group. In C, plasma glucose (G; mg/dL) rose by 17 +/- 5 at 10 minutes and 19 +/- 3 at 20 minutes due to an initial spike in Ra (2.7 +/- 0.2 to 4.9 +/- 0.5; P less than 0.01) at 10 minutes. INDO and S treatment attenuated this initial (10-20 minutes) rise in G (P less than 0.05) due to a lower s...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Hereditary Sensory Autonomic Neuropathy

Hereditary Sensory Autonomic Neuropathies are a group of inherited neurodegenerative disorders characterized clinically by loss of sensation and autonomic dysfunction. Here is the latest research on these neuropathies.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Landau-Kleffner Syndrome

Landau Kleffner syndrome (LKS), also called infantile acquired aphasia, acquired epileptic aphasia, or aphasia with convulsive disorder, is a rare childhood neurological syndrome characterized by the sudden or gradual development of aphasia (the inability to understand or express language) and an abnormal electroencephalogram. Discover the latest research on LKS here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.

Regulation of Vocal-Motor Plasticity

Dopaminergic projections to the basal ganglia and nucleus accumbens shape the learning and plasticity of motivated behaviors across species including the regulation of vocal-motor plasticity and performance in songbirds. Discover the latest research on the regulation of vocal-motor plasticity here.
