Adrenocortical oncocytoma is found very rarely. Most such tumours are benign and nonfunctioning. We report the case of a nonfunctioning adrenocortical oncocytoma located in the right adrenal gland in a 35-year-old man. The patient was tested because of arrhythmia. An adrenal mass of 68 × 64 mm was found during ultrasonography, followed by CT examination. Physical examination indicated obesity w...

The molecular mechanisms generating the mania-like abnormal behaviors caused by diacylglycerol (DG) kinase (DGK) η deficiency remain unclear. Here, we found that DGKη knockout markedly increased dopamine (DA) levels in midbrain (DA-producing region, 2.8-fold) and cerebral cortex (DA projection 1.2-fold). Moreover, significantly augmented phosphorylated DA transporter (DAT) (1.4-fold increase), ...

In vertebrates, the adrenocortical stress response activates an emergency life-history stage, which is thought to promote survival by helping individuals escape life-threatening situations. Although the adrenocortical stress response promotes many behavioural and physiological changes, it remains unclear whether this stress response actually translates into higher survival in wild vertebrates. ...

BACKGROUND Etomidate is a sedative-hypnotic that is often given as a single intravenous bolus but rarely as an infusion because it suppresses adrenocortical function. Methoxycarbonyl etomidate and (R)-ethyl 1-(1-phenylethyl)-1H-pyrrole-2-carboxylate (carboetomidate) are etomidate analogs that do not produce significant adrenocortical suppression when given as a single bolus. However, the effect...

The orphan nuclear receptor Steroidogenic Factor-1 (SF-1, NR5A1) is a critical regulator of development and homeostasis of the adrenal cortex and gonads. We recently showed that a complex containing E3 ubiquitin ligase RNF31 and the known SF-1 corepressor DAX-1 (NR0B1) interacts with SF-1 on target promoters and represses transcription of steroidogenic acute regulatory protein (StAR) and aromat...

Glucose-dependent insulinotropic peptide receptor (GIPR) and LHCGR are G-protein-coupled receptors with a wide tissue expression pattern. Aberrant expression of these receptors has rarely been demonstrated in adult sporadic adrenocortical tumors with a lack of data on pediatric tumors. We quantified the GIPR and LHCGR expression in a large cohort of 55 patients (25 children and 30 adults) with ...

It has been suggested that urinary steroid profiling may be used to provide information aiding the diagnosis and monitoring of adrenocortical carcinoma. Nonetheless, the abnormal patterns suggestive of adrenal malignancy are not well defined. We retrospectively studied the urinary steroid profiles of five patients with adrenocortical carcinoma at presentation and at follow-up, and compared thes...

The aim of the study is to present genes encoding enzymatic proteins of aldosterone and cortisol synthesis pathway, methods of their transcriptional activity measurement, mRNA expression of the genes in normal adrenal cortex, in adrenocortical adenomas excised from patients with Conn and Cushing syndromes, as well as in adrenocortical adenomas excised from patients, in which hormonal activity o...

URQUHART, JOHN. Adrenal blood Juw and the adrenocortical response to corticotropin. Am. JPhysiol. 2og(6) : I 162-l 168. 1g65.-The effect of variations in adrenal blood flow on the adrenocortical response to ACTH was studied. The rate of blood flow through the perfused canine adrenal gland was a significant parameter in its response to ACTH. This effect was largest when the concentration of ACTH...
