Neuroendocrine control of puberty in primates: differential involvement of two distinct populations of GnRH neurons?

Urbanski Henryk

Gonadotropin-releasing hormone (GnRH) neurons represent the primary neuroendocrine link between the brain and the reproductive system. Although they play a key role in stimulating the release of LH and FSH from the anterior pituitary gland, the underlying mechanism by which they trigger the onset of puberty is unclear. To address this issue, RT-PCR, in situ hybridization histochemistry, and Affymetrix gene arrays were used to profile hypothalamic GnRH gene expression in prepub...

Defining the impact of paternal diet on testicular morphology and apoptosis

Eid Nader , Morgan Hannah , Rouillon Charlene , Watkins Adam

While the association between maternal nutrition and female reproductive fitness and offspring health is well recognised, the role that paternal diet plays in shaping male reproductive health is relatively poorly understood. It is, however, well established that poor diet has adverse effects on sperm quality, which in turn have a negative impact on embryo development and offspring health. It is conceivable that behind any alterations to sperm quality, there are certain underly...

Placental expression of progesterone receptor is down regulated in fructose-induced diabetic rats

Ogunsola Oluseyi Abimbola , Iranloye Bolanle , Adegoke Feyiade

Maternal diabetes is known to impair placental function; however, its effect on placental expression of progesterone and oestrogen receptors has not been well documented. Fructose has been used to induce insulin resistance in animal models (Suga et al., 2000). The study aimed to assess maternal serum levels of progesterone, oestriol, oestradiol; placental morphology and its expression of progesterone and oestrogens receptors in fructose-induced diabetic rats. Twelve f...

Islet adaptations to pregnancy: a role for Urocortin 2

Simpson Sian , Smith Lorna , Jones Peter , Bowe James

Previous studies have shown beneficial effects of the corticotropin releasing hormone (CRH) family, including the urocortins (UCN1, UCN2 and UCN3), on pancreatic islets and subsequent glucose homeostasis. However, the physiological relevance of this interaction is not currently understood. CRH and urocortins are also expressed by placenta, so this study investigated whether signalling through CRH receptor 1 or 2 (CRHR1/CRHR2) plays a role in the islet adaptation to pregnancy. ...

Vitamin D binding protein (DBP) is required for pro-invasion effects of vitamin D on placental trophoblastic cells

Ganguly Ankana , Shattock Alexandra , Joseph Annsha , Gupta Janesh , Hewison Martin

The active form of vitamin D, 1,25-dihydroxyvitamin D (1,25(OH)2D) is abundant in decidua but its role in placental development is unclear. We hypothesized that decidual 1,25(OH)2D promotes placentation in early-pregnancy via actions on trophoblastic cell invasion. Using trophoblastic JEG3, BeWo and HTR8 cells we showed that 1,25(OH)2D has no effect on trophoblastic cell proliferation and migration in plasticware culture. However, in Matrigel t...

Impact of a FSHR positive allosteric modulator on FSH glycosylation variant-dependent FSHR homomerisation and signal pathway activation

Agwuegbo Uche , Albert Anthony , Bousfield George , Jonas Kim

The heterodimeric pituitary glycoprotein hormone, follicle-stimulating hormone (FSH) and its target G protein-coupled receptor (FSHR) are essential for reproduction. As an important drug target for IVF, the need for more effective treatment drives interest in understanding what modulates FSH/FSHR functions. In vivo, two predominant FSH glycosylation variants have been identified; partially glycosylated FSH (FSH21) has faster binding kinetics to the FSHR and is more potent at a...

miR-1-3p and miR-133-3p are altered in maternal serum EVs and placenta in pregnancies complicated by gestational diabetes with large-for-gestational age babies

Kennedy Margeurite , Cartland Sarah , Saravanan Ponnusamy , Simpson Nigel , Scott Eleanor , Forbes Karen

Gestational diabetes (GDM) is a form of diabetes that is first diagnosed during pregnancy, complicating 8–24% of all pregnancies. Despite treatment, substantial numbers of babies are born large for gestational age (LGA), predisposing them to cardio-metabolic disease in adulthood. It is difficult to predict which pregnancies are most at risk. The study aimed to determine if circulating maternal serum small extracellular vesicle (sEV) miRNAs have the potential to predict al...

Gonadotrophin rise following the kisspeptin analogue (MVT-602) is increased in women with hypothalamic amenorrhoea compared to healthy women

Eng Pei Chia , Abbara Ali , Phylactou Maria , Clarke Sophie A , Yang Lisa , Mills Edouard , Modi Manish , Papadopoulou Deborah , Plumptre Isabella , Hunjan Tia , Purugganan Kate , Webber Lisa , Salim Rehan , Comninos Alexander N , Dhillo Waljit S

Introduction: Hypothalamic amenorrhoea (HA) is a condition characterised by reduced GnRH pulsatility and is a common cause of anovulatory subfertility. Kisspeptin is an endogenous neuropeptide that regulates hypothalamic GnRH function. Hypothalamic kisspeptin expression is reduced, and kisspeptin receptor expression is increased, in a rodent model of HA. The kisspeptin analogue MVT-602 has a 3-4-fold longer half-life than native kisspeptin-54 (t1/2 0.5 h). We invest...

Igf2 regulates placental endocrine capacity in the mouse placenta

Aykroyd Bethany , Tunster Simon , Sferruzzi-Perri Amanda

Introduction: Abnormal fetal growth can cause perinatal morbidity and mortality. The placenta regulates materno-fetal nutrient transfer and secretes hormones with maternal physiological effects. In mice, global loss of insulin-like growth factor 2 (Igf2), a paternally-expressed imprinted gene, causes fetoplacental growth restriction in association with changes in placental transport and endocrine zone (Jz) formation. However, the role of Igf2 in regulating pl...

Oxytocin as a new target in treating ejaculatory disorders?

Stadler Beatrix , Kampschulte Marian , Wagenlehner Florian , Exintaris Betty , Middendorff Ralf

Oxytocin was suggested to affect sperm volume and ejaculation. The most distal part of the epididymis stores the sperm until ejaculation and was therefore our main focus when investigating parts of the rat epididymis and vas deferens for local differences of the contractile responses to oxytocin in comparison to norepinephrine regarding their usability for targeted drug development. Single loops of the coiled epididymal duct from defined parts of the epididymis and the adjacen...

Maternal cardiovascular risk and pregnancy outcomes in turner syndrome – new evidence supports current guidance

Calanchini Matilde , Bradley-Watson James , Orchard Elizabeth , Turner Helen E

Introduction: The risk of maternal death from aortic-dissection(AoD) during pregnancy/post-partum in TS is increased, due to TS-associated risk factors (bicuspid-aortic-valve(BAV), aortic-coarctation, aortic-dilatation, hypertension) and the increased cardiovascular strain of pregnancy itself. TS-guidelines advice against pregnancy in the presence of severe aortic-dilatation or moderate dilatation with AoD-risk factors; and after aortic surgery a high risk remains. However, fe...

Identifying placental hormones regulating maternal physiology during pregnancy – potential diagnostic and treatment markers for pregnancy complications

Napso Tina , Zhao Xiaohui , Lopez-Tello Jorge , Hamilton Russell S. , Sferruzzi-Perri Amanda N

Pregnancy is characterised by profound changes in maternal physiology. For instance, there are changes in the metabolic, cardiovascular, immune and renal systems of the mother which enable her to support fetal nutrient supply and growth. These changes are signalled in part by the production of protein hormones by the placenta (Napso et al., 2018). Failures in maternal adaptation and placental function lead to pregnancy complications such as abnormal birth weight and g...

Are all kisspeptins equal? The effect of kisspeptin 10 and kisspeptin 54 on kisspeptin-mediated signalling

Sachania Svaty , Nawar Naushin , Ghelut Aaron , Dhillo Waljit , Jonas Kim C

Kisspeptin (Kp) and its receptor (KISS1R) are essential for reproduction, with dysfunction in their activities leading to reproductive disorders, such as precocious puberty and hypogonadotrophic hypogonadism. Kp is synthesised and secreted within specialist nuclei of the hypothalamus, modulating the HPG axis. Kp is a 54 amino acid peptide, which can undergo proteolytic cleavage into smaller peptides, including Kp10, which retain biological activities. However, little is known ...

Deciphering the effects of testosterone on FSH glycosylation variant-dependent ERK/MAPK activation

Kellaway Jedidiah , Bousfield George , Jonas Kim

The heterodimeric glycoprotein hormone, follicle stimulating hormone (FSH) and its receptor (FSHR) are vital for reproductive function, driving ovarian function via follicular recruitment, selection and development. FSH exists as two predominant glycoforms in females; partially glycosylated (FSH21) and fully glycosylated (FSH24), based on differing glycosylation patterns of the β subunit. The FSH glycoforms have different bioactivities, with FSH21 displaying a higher bind...

Derivatisation of 5α-dihydrotestosterone enhances sensitivity of analysis of human plasma by liquid chromatography tandem mass spectrometry

Faqehi Abdullah , Denham Scott , Naredo-Gonzalezb Gregorio , Cobice Diego , Sabil Ghazali , Upreti Rita , Gibb Fraser , Homer Natalie , Andrew Ruth

Liquid Chromatography tandem mass spectrometry (LC–MS/MS) is gold-standard for androgen analysis in biological fluids, superseding immunoassays in specificity, particularly at low concentrations. While LC–MS/MS is well established for analysis of testosterone (T) and androstenedione (A4), 5α-dihydrotestosterone (DHT) presents greater analytical challenges. DHT circulates at low nanomolar concentrations in men and lower in women, ionising inefficiently. Thus, eve...

Investigating placental endocrine dysfunction in a translationally relevant mouse model of fetal growth restriction

Bertlin James , George Roberts , Tunster Simon

Fetal growth restriction (FGR), which describes the failure of a fetus to achieve its genetic growth potential, not only increases the risk of perinatal mortality and morbidity but also predisposes to metabolic disease in adulthood. In developed countries, FGR is typically attributed to dysfunction of the placenta – a transient organ that mediates nutrient supply, eliminates waste, and protects the fetus from maternal immune response. The placenta also functions as a majo...
