Differentially glycosylated FSHR ligands as potential modulators of FSHR quaternary complexes and FSHR-dependent signalling

Agwuegbo Uche , Colley Emily , Bousfield George , Albert Anthony , Jonas Kim

The G protein-coupled receptor, follicle-stimulating hormone receptor (FSHR), is essential for reproduction. A key drug target of IVF, understanding the mechanisms modulating FSHR functions remains of high importance. The endogenous ligand of the FSHR, FSH, is a heterodimeric glycoprotein hormone with two predominant glycoforms identified. Partially glycosylated FSH21 has faster binding kinetics to the FSHR and more potent at activating cAMP-dependent signal pathways, in compa...

Maternal fetuin-A (AHSG) serum levels are altered in pregnancies complicated by gestational diabetes and are associated with pathological fetal growth

Quilang Rachel , Gurung Dilasha , Scott Eleanor , Forbes Karen

Background: Gestational diabetes mellitus (GDM) is associated with increased rates of large-for-gestational-age (LGA) or small-for-gestational-age (SGA) infants. Currently, it is not possible to predict which women with GDM are at risk of delivering LGA or SGA infants. Fetuin-A, (α 2-Heremans Schmid glycoprotein; AHSG), a glycoprotein associated with insulin resistance is altered in GDM maternal serum. It is unclear if levels are related to altered fetal growth. This stud...

An exploration of the association between CAG repeat status and mortality in men

Heald Adrian , Cook Michael , Javed Ahmed , Fachim Helene , O’Neill Terence , Wu Fred

Introduction: The androgen receptor (AR) mediates the peripheral effects of testosterone. The main mechanism of action for the AR is direct regulation of gene transcription. Available evidence suggests that the number of CAG repeats in exon-1 of the AR gene is negatively correlated with transcriptional activity of the AR and that CAG repeat number links to mortality rate in T2DM men. The aim of this analysis was to determine the association between CAG repeat number and all ca...

The relationship between polycystic ovarian syndrome and fractures: A Mendelian randomization study using the UK Biobank

Shah Najeeb , Deshmukh Harshal , Aye Mo , Sathyapalan Thozhukat

Background: Polycystic ovary syndrome (PCOS) is believed to be a primeval condition with the earliest hints of its existence found in ancient Egyptian literature. Despite its negative impact on fertility, it has emerged as the most common endocrine disorder in women of reproductive age, creating what is called the PCOS paradox. We hypothesized that this phenomenon can be explained by testosterone-mediated high bone mineral density (BMD) in women with PCOS, providing a survival...

In vitro effects of dihydrotestosterone (DHT) on gonadotropin receptor function and steroidogenesis in human granulosa lutein cells

Anujan Priyanka , Owens Lisa , Alro Botkjaer Jane , Hanyaloglu Aylin , Hardy Kate , Franks Stephen

Polycystic ovary syndrome (PCOS) is a multifactorial, complex endocrine disorder affecting a significant proportion of the global population. Hyperandrogenism is a key feature of PCOS patients. Aberrant secretion and/or action of gonadotropins have been implicated in PCOS, but, to date, we have only limited knowledge of how these factors may interact in the aetiology of PCOS. We hypothesised that excess androgens may cause aberrant gonadotropin activity and therefore sought to...

The effect of exogenous kisspeptin administration in a novel mouse model of hypothalamic amenorrhoea

Shrewsbury Jed V , Ng Kah-Yan , McIntyre Caitlin , Li Xiao Feng , Phylactou Maria , O’Byrne Kevin T , Abbara Ali , Dhillo Waljit S , Owen Bryn M

Kisspeptin is integral to hypothalamo-pituitary-gonadal (HPG) axis function and overall fertility. Functional deficiency of GnRH/lH secretion in the central reproductive disease, hypothalamic amenorrhoea (HA), indicates diminished kisspeptin signalling. Clinical trials have shown kisspeptin to be a viable therapeutic intervention. However, repeated administration led to the development of tachyphylaxis and so is likely a problem for future implementation. Indeed, elevated LH r...
