Genome-wide map of AR-targets in human endometrial stromal cells treated with DHT.

ABSTRACT: Polycystic ovary syndrome (PCOS) is a common gynaecological disorder, characterised by elevated circulating androgens and aberrant expression of androgen receptor (AR) in the endometrium: The objective of this study is to evaluate the targets of AR in PCOS patients. Overexpression of AR and altered endometrial signalling pathways in PCOS patients may impact on a correct decidualization response, critically affecting the events surrounding embryo implantation and causing infertility.

Homeobox regulator Wilms tumour 1 (WT1) is displaced by androgen receptor at cis-regulatory sites in the endometrium of PCOS patients.

Project description:Polycystic ovary syndrome (PCOS) is a common gynaecological disorder, characterised by elevated circulating androgens and increased expression of androgen receptor (AR) and by downregulation of Wilms Tumour 1 in the endometrium, The objectives of this study are: 1) Understand the functional role of WT1 in regulating decidualization response in healthy endometrial tissue, and 2) understand how interactions between aberrant WT1 and AR expression in PCOS patients result in dysregulation of deciduallization processes

The Identification and Functional Analysis of CircRNAs in Endometrial Receptivity of Mice with Polycystic Ovary Syndrome

Project description:The disorders of endometrial receptivity and ovulatory dysfunction are both important causes of infertility of patients with Polycystic Ovary Syndrome (PCOS). The study aimed to investigate the expression profile and functional analysis of circRNAs in the endometrial receptivity of mice with PCOS. Twenty-four 4-week-old female C57BL/6 mice were randomly divided into two groups (PCOS group and Normal control group, n=12) and PCOS group was subcutaneously with DHEA 6mg/kg for 20 days. The circRNA expression profile in the endometrium tissue of two groups on the 4th day of gestation was screened by gene chip technique.

Novel PGK1 determines AR stability dependent on Spk2 and reprograms granular cell glucose metabolism to facilitate ovulation dysfunction

Project description:Ovulation disorder is the main characteristic of polycystic ovary syndrome (PCOS), but the concrete molecular mechanism is unclear. Phosphoglycerate kinase 1 (PGK1) plays an important role in the process of glycolytic cycles. Androgen and androgen receptor (AR) are considered as one of the critical factors in the prevalence of hyperandrogenemia and follicular development, and whether PGK1 participates in the metabolic reaction via AR in PCOS remains vague. PGK1 and AR proteins were highly expressed in PCOS luteinized granulosa cells and the PCOS-like mice ovary tissues. PGK1 increased lactate levels and deteriorated PCOS-like mouse metabolic disorder, and importantly, the phenotype of PCOS-like mice was rescued by PTX (paclitaxel) and the PGK1 and AR protein levels also decreased in the ovary. We demonstrated that PGK1 promoted AR translocation into the nuclear, and PGK1 was dependent on the E3 ligase Skp2 to repress the AR ubiquitination to improve the AR stability. In addition, we found that follicular development critical genes MAP2K6, KLF15, LRIG3 and MYOF were regulated by the PGK1-AR axis in the RNA-seq data, and axis also mediated cell proliferation and apoptosis. This study highlights the glycolysis key gene PGK1 to regulate metabolism in granular cell result in etiology of the PCOS. The PGK1-AR axis might provide a new therapy target of PCOS

Cistrome analyses of AR stimulated by 0.1 nM DHT in LNCaP stable cell line overexpressing AR [ChIP-Seq]

Project description:The molecular drivers for the AR signaling reprogramming in castration-resistant prostate cancer remain to be determined. In this study, we hypothesize that increased AR expression in conjunction with lower-level androgens, which is a typical condition in prostate cancer cells receiving androgen deprivation therapy, is a major driving force of the reprogramming. To test this, we used LNCaP model with inducible overexpression of AR to examine the acute effects of AR overexpression stimulated by low-dose DHT (0.1nM) on AR cistrome.

Seminal plasma promotes decidualization of endometrial stromal fibroblasts from women with and without inflammatory disorders in a manner dependent on IL11 signaling

Project description:SP promotes decidualization of eSF from women with and without inflammatory disorders (polycystic ovarian syndrome (PCOS), endometriosis) in a manner that is not mediated through semen amyloids and that is associated with a potent transcriptional response including induction of IL11, a cytokine important for SP-induced decidualization.

Gene expression in rat ovaries treated with DHT

Project description:Polycystic ovarian syndrome (PCOS) is an endocrine disorder of the reproductive and metabolic axis in women during the reproductive age. In this study, we used a rat model exhibiting reproductive and metabolic abnormalities similar to human PCOS to unravel the molecular mechanisms underlining this complex syndrome. Female Sprague-Dawley rats were implanted with a silicone capsule continuous-releasing 5Î±-dehydrotestestrone (DHT) per day for 12 weeks to mimic the hyperandrogenic state in women with PCOS, and the control (CTL) groups received an empty capsule. The animals were euthanized at 15 weeks of age and the ovarian cortex tissues of both groups were used for transcriptome profile analysis.

Coding and Non-coding gene expression signatures of endometrium from Polycystic Ovary Syndrome Patients

Project description:Polycystic ovary syndrome (PCOS), one of the most common endocrinal diseases among reproductive-aged women, is characterized by hyperandrogenemia, chronic oligo/anovulation and polycystic ovarian morphology. In this research, we presented microarrays to identify the differential expressed protein-coding genes and lncRNAs expression profile in the endometrium during the window of implantation between the PCOS and healthy subjects.
