Human adrenal NCI-H295R cells produce more C19 steroids than NCI-H295A cells – a possible model to study regulation of androgen biosynthesis?

Samandari Elika , Kempna Petra , Hoffer Gaby , Mullia Primus E , Fluck Christa E

The human adrenal cortex consists of three layers in which specific steroid hormones are produced. Human adrenal NCI-H295A (A) and NCI-H295R (R) cells, originate from the same adrenocortical tumor and express all genes essential for steroidogenesis. Therefore they often serve as a suitable model to study human steroidogenesis. No data are available comparing steroidogenesis of A vs. R cells. Assuming no difference, research data from these two cell lines are directly compared....

Inhibition of C17,20-lyase activity by new 17β-exo-heterocyclic androsterone derivatives

Szécsi Mihály , Tóth István , Wölfling János , Schneider Gyula , Julesz János

17α-Hydroxylase-C17,20-lyase (P45017α) is a key regulator enzyme of the steroid hormone biosynthesis in both the adrenals and the testes. Inhibition of this enzyme can block androgen synthesis in an early step, and may thereby be useful in the treatment of prostatic carcinoma, which is androgen-dependent in the majority of cases. Abiraterone and its analogues have been found strong inhibitors of P45017α suggesting that steroid de...

Leptin and adiponectin interact in regulating prostate cancer cell growth

Mistry Tina , Digby Janet , Desai Ken , Randeva Harpal

Introduction: Leptin and adiponectin have opposing properties and are implicated as molecular mediators between obesity and (aggressive) prostate cancer. Adiponectin, circulates inversely proportional to visceral fat accumulation, and has demonstrated anti-proliferative effects in prostate cancer cells; circulating leptin levels increase with visceral fat accumulation and has shown mitogenic effects. We propose that adiponectin and leptin interact in prostate cancer cell growt...

A novel role for Visfatin/Pre-B cell colony-enhancing factor 1 (PBEF)/Nicotinamide phosphoribosyltransferase (NMPRTase) in prostate carcinogenesis

Mistry Tina , Digby Janet , Cross Joe , Desai Ken , Randeva Harpal

Introduction: Visfatin/PBEF is a novel adipokine circulating inversely proportional to visceral fat mass and exerts insulin-mimetic effects; it is expressed in normal, inflamed and tumour tissues. Visfatin/PBEF has also been identified as NMPRTase, a key intracellular enzyme involved in NAD+ metabolism, replenishing NAD+ during cellular respiration. Inhibition of NMPRTase by the anti-cancer agent FK866 has been shown to induce apoptosis in tumours. Prosta...

Somatostatin analogues and the PI3K-AKT-MTOR-P70S6K pathway: how do they control the proliferation of neuroendocrine tumours?

Franchi Giulia , Grozinsky-Glasberg Simona , de Oliveira Antonio Ribeiro , Salahuddin Nabila , Korbonits Márta , Grossman Ashley B.

Background: Somatostatin analogues are very useful in the treatment of symptomatic neuroendocrine tumours, but effects on proliferation remain unclear. Overexpression of the proto-oncogene protein kinase Akt has been demonstrated in certain endocrine tumours, and activates downstream proteins including mTOR and p70S6K, which play a significant role in cell growth and proliferation. We have therefore explored the site of action of somatostatin in causing inhibition of prolifera...

The role of BMP-3B in the establishment of zona glomerulosa in the adrenal gland

Bakmanidis Artem , King Peter

The adrenal gland is composed of the medulla and the cortex, which is further subdivided into three zones: zona glomerulosa (zG), zona fasciculata (zF) and zona reticularis (zR). The zones of the cortex are functionally characterised by their ability to synthesise different steroids and consequently they express different steroidogenic enzymes. These and other markers of the zones have been described but so far no good candidate for a determining factor of zonal establishment ...

The orexigenic hormone NPY(1–36) is truncated by the dipeptidyl-inhibitor IV (DPP-IV) to NPY(3–36) as consequence its affinity changes from receptor Y1 to Y4 and 5. The aim was to investigate whether DPP-IV is expressed in adipose tissue (AT) where it could modulate adipose tissue growth through modulation of NPY activity. This is relevant in light of DPP-IV inhibitors utilised ...

Gs-dependent receptor endocytosis of melanocortin-4 receptors

Breit Andreas , Heling Dominik , Gudermann Thomas

Melanocortin receptors (MCR), which belong to the superfamiliy of G protein-coupled receptors (GPCR), are preferentially coupled to Gs proteins and play a major role in the regulation of energy homeostasis. In line with this notion, mutations in the MC4R gene are the most frequent monogenic cause of severe obesity in human beings. Recently it has been shown that the MC4R receptor undergoes, similar to most GPCR, GPCR kinase (GRK) and arrestin-mediated ligand-promoted receptor ...

Transthyretin is up-regulated by androgens in mice liver and choroid plexus

Santos Cecilia RA , Henrique Alves C , Saraiva Maria Joao , Abreu Raquel , Baltazar Graça , Socorro Silvia , Quintela Telma P , Gonçalves Isabel MT

Transthyretin (TTR) is well documented as a carrier for thyroid hormones. It also binds retinol binding protein preventing its filtration trough the kidneys and therefore is involved in delivering retinol to target cells. Moreover, TTR sequesters amyloid-beta impairing its deposition in nervous tissues and possibly contributing to its removal. Despite its importance in mammalian physiology, there are few studies regarding the regulation of TTR synthesis. In silico analy...

Tomisti Luca , Dell’Unto Enrica , Cosci Chiara , Sardella Chiara , Bartalena Luigi , Bogazzi Fausto , Martino Enio

Amiodarone induced thyrotoxicosis (AIT) may develop in patients with either underlying thyroid disorders (type 1) or normal gland (type 2). The latter is considered a drug-induced destructive thyroditis, usually responding to glucocorticoids. Further treatments after restoring euthyroidism are often not necessary. The former is a true form of iodine-induced hyperthyroidism the management of which includes thionamides, potassium perchlorate and thyrodectomy. The prevalence of t...
