We studied activity of the key enzyme of the pre-receptor metabolism of glucocorticoid hormones, 11β-hydroxysteroid dehydrogenase, in rat adrenal glands, renal cortex and liver in the course of development of alloxan diabetes (9, 20, and 28 day). The enzyme activity was increased 3-4 fold in the adrenal glands throughout the experiment. At the same time, according to the adrenal gland level of corticosterone, its precursor 11-deoxycorticosterone and reversible metabolite 11…

11β-Hydroxysteroid dehydrogenase in the rat adrenal
TLDR
Levels of mRNA encoding the glucocorticoid-dependent enzyme phenylethanolamine N-methyltransferase, which catalyses the conversion of noradrenaline to adrenaline, were also significantly reduced in those rats given glycyrrhizic acid, and was more uniformly distributed over the adrenal gland.

TLDR
Data support the use of 11β-HSD1 inhibitors to lower intracellular glucocorticoid levels and treat both obesity and its metabolic complications and the non-selective ‘prototype’ inhibitor carbenoxolone enhances insulin sensitivity in human subjects.
11beta-hydroxysteroid dehydrogenase and the pre-receptor regulation of corticosteroid hormone action.
TLDR
Here, the activation of cortisol from cortisone facilitates glucocorticoid hormone action at an autocrine level and answers a long standing conundrum relating to the set-point of 11beta-HSD1 activity.
Uninephrectomy reduces 11β-hydroxysteroid dehydrogenase type 1 and type 2 concomitantly with an increase in blood pressure in rats.
Renal allograft donors are at risk of developing hypertension. Here, we hypothesized that this risk is at least in part explained by an enhanced intracellular availability of
11β-Hydroxysteroid Dehydrogenase Type 1 Inhibitors as Promising Therapeutic Drugs for Diabetes: Status and Development
TLDR
Lowering intracellular glucocorticoid concentrations through administration of small molecule 11β-HSD1 selective inhibitors, significantly attenuates the signs and symptoms of disease in preclinical animal models and clinical trials of diabetes and metabolic syndrome.
Activity of 11β-hydroxysteroid dehydrogenase in tissues of hypertensive NISAG rats

TLDR
Functional activity of 11β-hydroxysteroid dehydrogenase probably reflects the hypertensive state of NISAG rats.
Adrenocortical system activity in alloxan-resistant and alloxan-susceptible Wistar rats
TLDR
In alloxan-susceptible rats, the mass index of adrenal gland is increased, and that of thymus is decreased and corticosterone concentration in blood, adrenal glands and urine as well as alanine and aspartate aminotransferase activities in liver are increased; in alloxa-resistant rats the values of these indices do not differ from those of rats of the control group.
Liver Is the Site of Splanchnic Cortisol Production in Obese Nondiabetic Humans
TLDR
The liver accounts for all splanchnic cortisol production in obese nondiabetic humans, and the viscera releases cortisone into the portal vein, thereby providing substrate for intrahepatic cortisol production.
