Background: The purpose of this study was to determine the incidence of premature luteinization in patients with polycystic ovary syndrome and compared the main determinants of success in IVF in PCOS patients with and without premature luteinization.Methods: Retrospective analysis of 180 PCOS women of Chinese Han origin with infertility who underwent controlled ovarian hyperstimulation (COH) with an exogenous gonadotropin/GnRH antagonist protocol. Hormon...

Background: A moderately high fructose diet fed to rat dams shifts the secondary sex ratio in the litters towards males. These dams, as well as diabetic pregnant mice, have elevated plasma glucose. Hence, high uterine fluid glucose or a hormone that may mark high glucose, may result in preferential selection of Y-bearing sperm at the point of fertilisation through effects of glucose on sperm motility. In this study, we assessed sperm motility after incubation in media with/wit...

Introduction: Chronic kidney disease (CKD) is a devastating condition characterised by progressive loss of renal function that leads to end-stage renal disease. In patients with CKD there is increased prevalence of subclinical hypothyroidism. The importance of thyroid hormone (TH) action on kidney development, growth and physiology has been established, however the role of TH on kidney disease progression is not well understood.Aim: To assess the express...

Background Somatostatin has many putative biological effects in the kidney such as influencing renal blood flow and urine volume, tubular transport and cell regulation. It exerts these effects via five identified G-protein linked receptors. However, only somatostatin receptor proteins 1 and 2A have been described in human kidney so far. In this study, we examined the distribution of somatostatin receptors (SSTRs) in normal human adult kidney. Methods Formalin fixed paraffin em...

The retinoic acid receptor gamma (RARg, encoded by NR1B3/RARG) is significantly downregulated but not mutated in the MSKCC and PRAD prostate cancer (PCa) cohorts in the Cancer Genome Atlas (TCGA) data. We investigated the consequences of modifying RARg expression.Independent of ligand, stable RARg knockdown stimulated RWPE-1 and LNCaP cells proliferation, changed the cell cycle profile and significantly altered global gene expression patterns th...

Pharmacokinetics and tolerability of a new a bioadhesive buccal testosterone tablet in testosterone deficient men.RJM Ross, A Jabbar, H Jones, B Roberts, K Dunkley, A Long, H Levine, DR CullenObjectives: A phase I single centre, open label study of the pharmacokinetics and tolerability of a buccal testosterone tablet (COL1621). Design: The study was approved by The South Sheffield Ethics Committee. Twelve testosterone deficient males were treated with the buccal tablet...

In normal physiology, glucocorticoid receptor (GR) activation regulates cell type-dependent genes whose products influence metabolism, inflammation, cell cycle and apoptosis/cell survival pathways. Synthetic GR agonists, or glucocorticoids (GCs), are often used to treat hematologic malignancies because of GR’s ability to induce proapoptotic gene expression, inhibit nuclear factor–κB, and induce cell cycle arrest. In contrast, recent examination of GR expression ...

The corepressor NCOR2/SMRT regulates multiple nuclear receptors (NRs) and other transcription factors. Disruption to these functions are implicated in prostate cancer (PCa) progression but the details remain enigmatic. Therefore we sought to define the global functions of NCOR2/SMRT using isogenic PCa cell models, PCa mouse models and human PCa cohorts.We mapped the NCOR2 dependent transcriptome (RNA-seq), miRnome (miRNA-seq), methylome (EPIC methylation...

Objective: The purpose of this study was to describe the outcome after initiation of exenatide therapy and to determine whether the impact of adverse drug reactions on compliance was affected by gender.Methods: A retrospective study was performed of 18 diabetic patients (eight males) that were prescribed exenatide between June 2013 and September 2014. Each included patient received exenatide for ≥1 month. Age, disease course, race, BMI, medical his...

Objective: To investigate the impact of lifestyle intervention on elevated thyroid peroxidase (TPO) antibody levels in outpatients with normal thyroid function.Methods: A retrospective cohort study was performed to observe and evaluate euthyroid patients with excessive TPO antibodies that presented to the authors’ hospital between March 2013 and October 2014 for routine medical examinations. The subjects were randomly divided into the lifestyle inte...
