Project description:The effects of how obesity and elevated androgen levels in women with polycystic ovary syndrome (PCOS) affect their offspring are unclear. We found that daughters of PCOS mothers are more likely to be diagnosed with PCOS in a Swedish nationwide register-based cohort and a clinical case-control study from Chile. Further, female mice (F0) with PCOS-like traits induced by late gestation injection of dihydrotestosterone, with and without obesity, produced female F1–F3 offspring with a PCOS-like reproductive and metabolic phenotypes. Sequencing of single MII oocytes from F1–F3 offspring revealed common and unique altered gene expression across all generations. Notably, four genes were also differentially expressed in serum samples from daughters in the case-control study and unrelated women with PCOS. Our findings provide evidence of transgenerational effects in female offspring of PCOS mothers and identify possible candidate genes for the prediction of a PCOS phenotype in future generations.

Project description:Polycystic ovary syndrome (PCOS) is a common disorder encompassing reproductive, metabolic, and endocrine abnormalities, affecting 5 to 10% of women of reproductive age.To reveal the differences in proteomic profiles of follicular fluid between patients with and without PCOS and explore possible mechanisms underlying PCOS.Follicular fluid samples were collected from 9 infertile patients with PCOS and 9 infertile patients without PCOS. Quantitative proteomics analysis based on mass spectrometry was used to measure the protein levels and understand the protein networks. The tandem mass tag (TMT) based proteomics technology and bioinformatics analysis were used to determine the differentially expressed proteins(DEPs). : In this study, we have identified a total of 1216 proteins,these included 70 DEPs, in which 32 proteins were upregulated, and 38 proteins were downregulated. The bioinformatics analyses revealed multiple biological functions associated with these DEPs, some DEPs were enriched in the immune and metabolic-related biological processes in PCOS patients.

Project description:Polycystic ovary syndrome (PCOS), the most common endocrine disease in reproductive-aged women, is associated with an increased prevalence and extent of coronary artery disease. However, the underlying mechanism remains unclear. Here, we observed that hearts from PCOS mice were characterized by increased total macrophage accumulation. Monocyte-derived macrophages were significantly increased in the hearts of PCOS mice owing to enhanced circulating monocyte supply. Compared with control mice, PCOS mice showed a significant increase in splenic monocyte output, associated with elevated hematopoietic progenitors in the spleen and sympathetic tone. Compared with non-PCOS animals, PCOS-induced mice showed significantly exacerbated atherosclerotic plaque development and post-MI cardiac remodeling. Conditional Vcam1 silencing in PCOS mice significantly suppressed cardiac inflammation and improved post-MI cardiac injury. Our data documented new mechanisms through which PCOS may affect cardiovascular health in women.

Project description:Polycystic ovary syndrome (PCOS) is a common reproductive system disease, with hyperandrogenism as the core feature. The pathologies remain to be illustrated. Long noncoding RNAs (lncRNAs) has been proved to be involved in various biological processes of human diseases. However, there were few reports about the research on lncRNAs in PCOS, not to mention hyperandrogenism.

Project description:To explore the molecular mechanisms of obesity and insulin resistance in the patients with polycystic ovary syndrome (PCOS) at the level of human embryonic stem cells (hESCs).Three PCOS-derived and one non-PCOS-derived hESC lines were induced into adipocytes, and then total mRNA was extracted from these adipocytes. The differential genes between PCOS-derived and non-PCOS-derived adipocytes were identified with GeneChip, and then were validated with real-time PCR.There were 153 differential genes. Of the 153 genes, 91 genes were up-regulated and 62 down-regulated. Nuclear receptor subfamily 0, group B, member 2 (NR0B2) was an up-regulated gene, and GeneChip software system indicated that it was associated with obesity and diabetes. Three PCOS-derived and one non-PCOS-derived hESC lines were induced into adipocytes, and then total mRNA was extracted from these adipocytes. The differential genes between PCOS-derived and non-PCOS-derived adipocytes were identified with GeneChip, and then were validated with real-time PCR.

Project description:Obesity has been linked with a host of metabolic and reproductive disorders including polycystic ovary syndrome (PCOS). While a distinct link exists between obesity and PCOS, the exact pathogenesis of the disease remains less understood and limited research has explored the impact of diet on the development of PCOS. With the primary symptoms of PCOS including hyperandrogenism, anovulation, and polycystic ovaries, most animal models utilize androgen treatment to effectively induce PCOS. However, these models fail to address the underlying causes of disease symptoms and do not effectively demonstrate the metabolic features of the disease such as hyperinsulinemia. Here, we present a novel rodent model of diet-induced obesity that recapitulates both the metabolic and reproductive phenotypes of human PCOS. In utilizing a high-fat high-sugar (HFHS) diet, we have created a model of PCOS that allows for the study of metabolic parameters and their impact on ovarian follicle development and reproductive health. Animals on the HFHS diet not only demonstrated signs of metabolic impairment, but they also developed polycystic ovaries and experienced irregular estrous cycling marked by an extended period spent in estrus. Though hyperandrogenism was not characteristic of HFHS diet animals as a group, testosterone levels were predictive of a polycystic ovarian morphology. Importantly, PCOS was induced similarly to the disease etiology in humans, allowing this model to offer the unique opportunity to study PCOS at its genesis rather than following the development of disease symptoms.

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.
