Evaluation of the expression of vesicular protein (SNARE) isoforms in human pituitary adenomas

Garcia Edwin , Trivellin Giampaolo , Michael Powell , Grieve Joan , Sabin Ian , Alusi Ghassan , Louis Pobereskin , Shariati Babak , Roncaroli Federico , Mendoza Nigel , Grossman Ashley , Harper Elaine , Korbonits Marta

Background: Botulinum neurotoxin inhibits muscle function by interfering with neurotransmitter release from secretory vesicles. The mechanism underlying this effect involves cleavage of SNARE proteins which are required for vesicle docking at the plasma membrane. The ability of botulinum neurotoxin serotypes to cleave SNARE proteins and inhibit secretion is being exploited for therapeutic purposes by Syntaxin Ltd with their targeted secretion inhibitor technology (...

Management of prolactinomas during pregnancy - A survey of four canadian provinces

Almalki Mussa , Johnson Michelle , Ur Ehud , Clarke David , Imran Syed Ali

The guidelines for management of prolactinomas (PRLoma) during pregnancy are mostly based on retrospective evidence or expert opinion. We conducted a survey of four Canadian provinces (NS, NB, PEI and BC) to assess the current trends in management of PRLoma during pregnancy. A case-based electronic questionnaire was sent to all practicing endocrinologists, with 3 cases of varying severity ranging from a micro PRLoma to a large macroPRLoma compressing the optic chiasm. A total ...

Ultrastructural changes in somatotrophs and gonadotrophs in TPit null mice

Yick Lok , Khetchoumian Konstantin , Drouin Jacques , Christian Helen

Tpit is a pituitary-specific transcription factor that is important for corticotroph terminal differentiation. In TPit null mice corticotroph cells do not differentiate and cells immunopositive for SF1, LH and FSH are observed in the intermediate lobe (Pulichino et al. 2003 Genes Dev). As the anterior lobe in TPit null mice showed a 50% decrease in cell number compared to wild-type (WT), and corticotrophs comprise only 57% of anterior lobe cells, we investigated c...

Mechanisms underlying termination of acute gonadotrophin-releasing hormone (GnRH)-stimulated ERK activation.

Finch Ann , Caunt Christopher , Perrett Rebecca , McArdle Craig

GnRH acts via G-protein coupled receptors to stimulate phospholipase C. This activates protein kinases C, driving the activation of extracellular signal regulated kinases (ERKs) that mediates transcriptional effects of GnRH. GnRH is secreted in pulses that cause rapid, transient and reproducible ERK activation (1). ERK response kinetics dictate biological consequences in many systems and, although GnRH-mediated ERK activation has been thoroughly explored, little is known about...

Transcriptional regulation of prolactin in the rat oestrous cycle

Patist Amanda , Featherstone Karen , Spiller David , Semprini Sabrina , McNeilly Judith , McNeilly Alan , Mullins John , White Michael , Davis Julian

Circulating levels of prolactin are subject to acute and long-term regulation by many factors including oestrogen and dopamine. We have studied the regulation of prolactin promoter activity in living pituitary cells using transgenic Fischer rats in which reporter gene expression is regulated by the human prolactin gene locus (hPRL-d2EGFP). We have previously identified pulsatile prolactin transcription patterns in living lactotroph cells in fetal tissue, that became stabilised...

Can the stability of variant aryl hydrocarbon receptor interacting protein (AIP) be a marker for pathogenicity in FIPA (familial isolated pituitary adenoma)?

Martucci Federico , Trivellin Giampaolo , Garcia Edwin , Dalantaeva Nadezhda , Chapple Paul , Pecori Giraldi Francesca , Grossman Ashley , Korbonits Marta

Background: 20% of the familial isolated pituitary adenoma (FIPA) population harbour an aryl hydrocarbon receptor-interacting protein (AIP) gene mutation. The recognition of whether a variant is pathogenic can be difficult, in cases where the observed change does not lead to a truncated protein. Segregation with disease in a family, in silico predictions, loss of heterozigosity in the tumour, in vitro functional studies and screening of the variant in controls may help in asce...

Development of a platform technology to generate long-acting protein therapeutics

Parry Heather , Thorpe Alice , Wilkinson Ian , Pradnanhanga Sarbendra , Sayers Jon , Artymiuk Peter , Ross Richard

Background: The development of recombinant biologics such as interferon, insulin and Growth Hormone (GH) has had a major impact on the management of diseases including hepatitis, diabetes and GH-deficiency. However, most biologics undergo rapid renal filtration and proteolytic degradation, necessitating frequent dosing regimens. Pegylation can successfully delay clearance but has several drawbacks including potential toxicity, expense and reduced activity. There is therefore n...

High prevalence of pituitary adenomas in patients with Macroprolactinaemia and oligo-/amenorrhoea

Gasior-Perczak Danuta , Lewandowski Krzysztof , Kowalska Aldona , Lewinski Andrzej

Background: The so called big-big prolactin, also known as macroprolactin is formed by prolactin-immunoglobulin complexes, and is considered to be biologically inactive. Nevertheless, macroprolactin may cause elevation of serum prolactin (Prl) concentrations measured by standard assays. In women presenting with oligo- and/or amenorrhoea the cause of menstrual irregularity needs to be explained even in the setting of concomitant macroprolactinaemia. We have therefor...

Acromegaly causes a distinct cardiomyopathy. Growth hormone deficiency (GHD) limits cardiac response to exercise and increases cardiac mortality. Cardiac magnetic resonance imaging (CMR) is considered the gold standard for assessment of cardiac mass and provides data on function, fibrosis, valves and ischaemia. Twenty-three patients with abnormal GH levels (acromegaly, n=13; adult-onset GHD, n=10) and 23 matched controls underwent CMR. Patients had repeat CMR at ...

Discordance between growth hormone and IGF1 in patients with acromegaly following recent guidelines

Scally Niamh , Swords Francesca , Gorick Sondra , Chipchase Alison , Temple Rosemary

Introduction: Discordance between growth hormone (GH) and insulin-like growth factor 1 (IGF1) is observed in up to 30% patients with acromegaly, with the most common finding being high IGF1 with normal GH levels. Recently published guidelines recommended a nadir GH of 0.4 μg/L rather than 1.0 during growth hormone suppression test as being indicative of controlled disease. This may lead to reduced discordance between GH and IGF1. Methods We measured nadir GH (Beckman Coul...

Pituitary regrowth following growth hormone replacement therapy.

Introduction: Growth hormone (GH)-deficiency in adults is associated with a range of adverse outcomes that improve with GH replacement. Pituitary adenomas and their treatment account for a large proportion of patients with adult GH-deficiency. However, safety fears have arisen due to the mitogenic effect of excess GH on pre-malignant colonic polyp formation in individuals with acromegaly. This, along with anecdotal suggestions of pituitary tumour recurrence, has prompted furth...

Distinct signalling cascades mediate GnRH pulse frequency-dependent differential regulation of FSHβ transcription via CREB and ICER activation

Thompson Iain , Ciccone Nick , Xu Shuyun , Carroll Rona , Kaiser Ursula

GnRH is released from the hypothalamus in a pulsatile manner and binds to specific receptors (GnRHR) in the anterior pituitary gland to stimulate follicle-stimulating hormone (FSH) and luteinizing hormone (LH) subunit gene expression and subsequent FSHβ and LHsecretion. The FSH and LH subunits are preferentially stimulated by pulsatile GnRH at low and high pulse frequencies, respectively.
