Endogenous glucose production in critical illness.

Nutr Clin Pract 2021 Mar 8. Epub 2021 Mar 8.

Division of Pulmonary, Allergy, and Critical Care Medicine, University of Pittsburgh, Pittsburgh, Pennsylvania, USA.

Regulation of endogenous glucose production (EGP) by hormonal, neuronal, and metabolic signaling pathways contributes to the maintenance of euglycemia under normal physiologic conditions. EGP is defined by the generation of glucose from substrates through glycogenolysis and gluconeogenesis, usually in fasted states, for local and systemic use. Abnormal increases in EGP are noted in patients with diabetes mellitus type 2, and elevated EGP may also impact the pathogenesis of nonalcoholic fatty liver disease and congestive heart failure.

Profiling of Steroid Metabolic Pathways in Human Plasma by GC-MS/MS Combined with Microwave-Assisted Derivatization for Diagnosis of Gastric Disorders.

Int J Mol Sci 2021 Feb 13;22(4). Epub 2021 Feb 13.

Department of Pharmacy, College of Pharmacy, Kyung Hee University, Seoul 02447, Korea.

Steroid hormones are associated in depth to cellular signaling, inflammatory immune responses, and reproductive functions, and their metabolism alterations incur various diseases. In particular, quantitative profiling of steroids in plasma of patients with gastric cancer can provide a vast information to understand development of gastric cancer, since both sex hormones and glucocorticoids might be correlated with the pathological mechanisms of gastric cancer. Here, we developed a gas chromatography-tandem mass spectrometry-dynamic multiple reaction monitoring (GC-MS/MS-dMRM) method combined with solid-phase extraction (SPE) and microwave-assisted derivatization (MAD) to determine 20 endogenous steroids in human plasma.

5-lipoxygenase- and Glucocorticoid-dependent eosinophilia in a novel surgical model in mice.

Int Immunopharmacol 2021 Feb 12;94:107440. Epub 2021 Feb 12.

Dept. Immunology, Instituto de Microbiologia Paulo de Góes, UFRJ, Rio de Janeiro, Brazil. Electronic address:

Background: Subcutaneous implants of heat-coagulated egg white (egg white implants, EWI) induce intense local eosinophilia and prime for hyperreactivity following airway ovalbumin challenge. The roles of allergen sensitization, surgical trauma-induced glucocorticoids, and the 5-lipoxygenase (5-LO) pathway were hitherto unexplored in this model, in which quantitative recovery and large-scale purification of the eosinophils from the inflammatory site for functional and immunopharmacological studies are difficult to achieve.

Methods: We overcame this limitation by shifting the implantation site to the peritoneal cavity (EWIp), thereby enabling quantitative leukocyte retrieval. Read More

Glucocorticoid agonists enhance retinal stem cell self-renewal and proliferation.

Stem Cell Res Ther 2021 Jan 25;12(1):83. Epub 2021 Jan 25.

Department of Molecular Genetics, University of Toronto, Toronto, ON, M5S 1A8, Canada.

Background: Adult mammalian retinal stem cells (RSCs) readily proliferate, self-renew, and generate progeny that differentiate into all retinal cell types in vitro. RSC-derived progeny can be induced to differentiate into photoreceptors, making them a potential source for retinal cell transplant therapies. Despite their proliferative propensity in vitro, RSCs in the adult mammalian eye do not proliferate and do not have a regenerative response to injury. Read More

Exposure to glucocorticoids alters life history strategies in a facultatively paedomorphic salamander.

J Exp Zool A Ecol Integr Physiol 2021 Mar 19;335(3):329-338. Epub 2021 Jan 19.

Department of Biology, The University of Mississippi University, MS, United States of America.

Polyphenisms, where two or more alternative, environmentally-cued phenotypes are produced from the same genotype, arise through variability in the developmental rate and timing of phenotypic traits. Many of these developmental processes are controlled or influenced by endogenous hormones, such as glucocorticoids, which are known to regulate a wide array of vertebrate ontogenetic transitions. Using the mole salamander, Ambystoma talpoideum, as a model, we investigated the role of glucocorticoids in regulating facultative paedomorphosis, an ontogenetic polyphenism where individuals may delay metamorphosis into terrestrial adults.

HIF1α is a direct regulator of steroidogenesis in the adrenal gland.

Cell Mol Life Sci 2021 Apr 19;78(7):3577-3590. Epub 2021 Jan 19.

Institute of Clinical Chemistry and Laboratory Medicine, Technische Universität Dresden, Fetscherstrasse 74, 01307, Dresden, Germany.

Endogenous steroid hormones, especially glucocorticoids and mineralocorticoids, derive from the adrenal cortex, and drastic or sustained changes in their circulatory levels affect multiple organ systems. Although hypoxia signaling in steroidogenesis has been suggested, knowledge on the true impact of the HIFs (Hypoxia-Inducible Factors) in the adrenocortical cells of vertebrates is scant. By creating a unique set of transgenic mouse lines, we reveal a prominent role for HIF1α in the synthesis of virtually all steroids in vivo. Read More

DNA methylome signatures of prenatal exposure to synthetic glucocorticoids in hippocampus and peripheral whole blood of female guinea pigs in early life.

Transl Psychiatry 2021 01 18;11(1):63. Epub 2021 Jan 18.

Department of Physiology, University of Toronto, Toronto, ON, Canada.

Synthetic glucocorticoids (sGC) are administered to women at risk of preterm delivery, approximately 10% of all pregnancies. In animal models, offspring exposed to elevated glucocorticoids, either by administration of sGC or endogenous glucocorticoids as a result of maternal stress, show increased risk of developing behavioral, endocrine, and metabolic dysregulation. DNA methylation may play a critical role in long-lasting programming of gene regulation underlying these phenotypes. Read More

Early pregnancy maternal progesterone administration alters pituitary and testis function and steroid profile in male fetuses.

Sci Rep 2020 12 14;10(1):21920. Epub 2020 Dec 14.

MRC Centre for Reproductive Health, The University of Edinburgh, Edinburgh, EH16 4TJ, UK.

Maternal exposure to increased steroid hormones, including estrogens, androgens or glucocorticoids during pregnancy results in chronic conditions in offspring that manifest in adulthood. Little is known about effects of progesterone administration in early pregnancy on fetal development. We hypothesised that maternal early pregnancy progesterone supplementation would increase fetal progesterone, affect progesterone target tissues in the developing fetal reproductive system and be metabolised to other bioactive steroids in the fetus.

Glucocorticoid ultradian rhythmicity differentially regulates mood and resting state networks in the human brain: A randomised controlled clinical trial.

Psychoneuroendocrinology 2021 Feb 1;124:105096. Epub 2020 Dec 1.

Laboratories of Integrative Neuroscience and Endocrinology, School of Clinical Sciences, University of Bristol, BS1 3NY Bristol, United Kingdom; Royal Bristol Infirmary, University Hospitals Bristol NHS Foundation Trust, BS2 8HW Bristol, United Kingdom.

Adrenal glucocorticoid secretion into the systematic circulation is characterised by a complex rhythm, composed of the diurnal variation, formed by changes in pulse amplitude of an underlying ultradian rhythm of short duration hormonal pulses. To elucidate the potential neurobiological significance of glucocorticoid pulsatility in man, we have conducted a randomised, double-blind, placebo-controlled, three-way crossover clinical trial on 15 healthy volunteers, investigating the impact of different glucocorticoid rhythms on measures of mood and neural activity under resting conditions by recruiting functional neuroimaging, computerised behavioural tests and ecological momentary assessments. Endogenous glucocorticoid biosynthesis was pharmacologically suppressed, and plasma levels of corticosteroid restored by hydrocortisone replacement in three different regimes, either mimicking the normal ultradian and circadian profile of the hormone, or retaining the normal circadian but abolishing the ultradian rhythm of the hormone, or by our current best oral replacement regime which results in a suboptimal circadian and ultradian rhythm.

Is there a safe and effective way to wean patients off long-term glucocorticoids?

E H Baker

Br J Clin Pharmacol 2020 Dec 1. Epub 2020 Dec 1.

Clinical Pharmacology and Therapeutics Section, Institute of Medical and Biomedical Education, St George's University Hospitals NHS Foundation Trust, London, UK.

Glucocorticoids are highly effective medicines in the treatment of inflammatory disorders. However they cause severe adverse reactions, particularly where taken at high doses systemically for prolonged periods. Systemic glucocorticoids are therefore given at dosage sufficient to control the disease, then withdrawn as fast as is possible to minimise dose- and time-related adverse drug reactions without losing disease control.

Pathophysiological implications of neuroinflammation mediated HPA axis dysregulation in the prognosis of cancer and depression.

Mol Cell Endocrinol 2021 01 27;520:111093. Epub 2020 Nov 27.

Laboratory of Cellular and Molecular Neurobiology, School of Life Sciences, Jawaharlal Nehru University, New Delhi, 110067, India. Electronic address:

Cancer patients are more likely to develop depressive symptoms and show a poor prognosis compared to the normal healthy individuals. Cancer occurrence and the anticancer treatments result in the pro-inflammatory cytokines-mediated inflammation, which dysregulates the HPA-axis activity that may result in depression-like behaviour. Conversely, depression causes the activation of the HPA-axis that results in the downstream release of endogenous glucocorticoids which may result in depressive signs and symptoms in some cancer patients.

Local steroid activation is a critical mediator of the anti-inflammatory actions of therapeutic glucocorticoids.

Ann Rheum Dis 2021 02 8;80(2):250-260. Epub 2020 Nov 8.

Research into Inflammatory Arthritis Centre, Versus Arthritis, Institute of Inflammation and Ageing, University of Birmingham, Birmingham, UK

Objectives: The enzyme 11β-hydroxysteroid dehydrogenase type 1 (11β-HSD1) plays a well-characterised role in the metabolism and activation of endogenous glucocorticoids (GCs). However, despite its potent upregulation at sites of inflammation, its role in peripheral metabolism and action of therapeutic GCs remains poorly understood. We investigated the contribution of 11β-HSD1 to the anti-inflammatory properties of the active GC corticosterone, administered at therapeutic doses in murine models of polyarthritis. Read More
