OCT4 immunostaining has become an essential resource in diagnosing germ cell neoplasia. OCT4 is a transcription factor with a characteristic nuclear staining pattern specific to germ cell neoplasms. Our institution has observed that paraganglionic tissue consistently displayed intense cytoplasmic staining by utilizing monoclonal OCT4 antibody, and we intended to determine whether OCT4 could pro...

The adrenal cortex is innervated by afferent fibers that have been implicated in affecting cortical steroidogenesis. Modulation of neurotransmitter release from afferents may represent a regulatory system for the control of adrenal cortical function. The present studies validate an in vitro superfusion technique for adrenal capsules employing the drug capsaicin, which activates a subset of affe...

Adrenal toxicity is one of the major concerns in drug development. To quantitatively understand the effect of endocrine-active compounds on adrenal steroidogenesis and to assess the human adrenal toxicity of novel pharmaceutical drugs, we developed a mathematical model of steroidogenesis in human adrenocortical carcinoma NCI-H295R cells. The model includes cellular proliferation, intracellular ...

Aldosterone is a cardiovascular hormone with key role in blood pressure regulation, among other processes, mediated through its targeting of the mineralocorticoid receptor renal tubule and selected tissues. Its secretion from adrenal gland highly controlled process subject to regulatory influence renin–angiotensin system hypothalamic–pituitary–adrenal axis. MicroRNAs are small endogenous non-co...

Adrenocortical carcinoma (ACC) is an uncommon malignancy originating from cortex of adrenal gland. The most common pitfall in diagnosis of ACC is to distinguish it from pheochromocytoma. Here we report a 62-year-old hypertensive man with presentation of dyspnea. The laboratory data showed an increase in urine cortisol and renin with a mild increase in aldosterone, but decrease in adrenocorticot...

Lymphoma may occasionally involve the adrenal glands, but primary adrenal lymphoma (PAL) is very rare and only few cases have been reported. We present a case of a 60-year-old, otherwise healthy, woman, with bilateral PAL presenting with adrenal insufficiency. The patient responded initially upon administration of large doses of intravenously hydrocortisone with total remission of symptoms. An ...

We examined the effect of angiotensin I (AI), without the effect of angiotensin II (AII) converted from AI, on the weight of the adrenal glands, adrenal corticosterone (B) and adrenal aldosterone under conditions where the renin-angiotensin system was suppressed, since a reduction in the size of the adrenal glands is often observed in DOCA/salt hypertensive rats. Sixty male Wistar rats fed on a...

The adrenal glands consist of an outer cortex and an inner medulla, and their primary purposes include hormone synthesis and secretion. The adrenal cortex produces a complex array of steroid hormones, whereas the medulla is part of the sympathetic nervous system and produces the catecholamines epinephrine and norepinephrine. In the mouse, GATA binding protein (GATA) 4 and GATA6 transcription fa...

Nicotine is a powerful stimulant of the sympathoadrenal system, causing the release of peripheral catecholamines and activation of catecholamine biosynthesis. In previous reports, we have studied the mechanisms by which short-term nicotine treatment regulates tyrosine hydroxylase (TH) in adrenal medulla. In this report, we study the effects of chronic nicotine treatment on adrenal TH gene expre...
