Project description:Polycystic ovary syndrome (PCOS) is a common reproductive endocrine disease characterized by persistent anovulation and hyperandrogenism, affecting approximately 8%-10% of women of childbearing age and occupying an important position in the etiology of infertility. There is increasing evidence that lncRNAs are involved in the development of PCOS, but the potential regulatory mechanism is still unclear. This study performed high-throughput lncRNA sequencing of follicular fluid exosomes in non-PCOS infertility patients and PCOS infertility patients. The sequencing results led to the identification of 1253 upregulated and 613 downregulated lncRNAs from a total of 1866 detected candidates. There was no significant difference between the PCOS patients and non-PCOS patients in body mass index (BMI) or the fasting blood glucose (FBG) level. However, luteinizing hormone (LH), estradiol (E2), testosterone (T), serum prolactin (PRL) and anti-Mullerian hormone (AMH) levels were clearly upregulated in PCOS patients compared to those in non-PCOS patients. There was also an increase in LH/FSH (>2) in the PCOS patients. Functional analysis showed that the functions of lncRNAs were related to adenine metabolism, adenine biosynthesis and cytidine triphosphate biosynthesis. These results suggest that lncRNAs may play an important role in the pathogenesis of PCOS and may be potential targets for the diagnosis and treatment of PCOS.

Project description:Purpose: the goals of this study are to identify the transcriptome profiling of exosome derived from follicle fluid of PCOS patients by next-generation sequencing (NGS). Methods:the transcriptome profiling of exosome derived from follicular fluid of five PCOS and five control patients were generated by deep sequencing, using Illumina GAIIx. The sequence reads that passed quality filters were analyzed at the transcript isoform level with two methods: Burrows–Wheeler Aligner (BWA) followed by ANOVA (ANOVA) and TopHat followed by Cufflinks. qRT–PCR validation was performed using TaqMan and SYBR Green assays Results: the transcriptome profiling including circRNA, lncRNA and mRNA were comparatively analyzed in the two groups of exosomes (exo-PCOS and exo-control). We focus on the circRNAs profile for further analysis. A circRNA candidate was considered to be differentially expressed if its levels between both experiment groups showed a statistically significant difference (p<0.05) of at least two-fold. Based on this criterion, we identified 16 differentially expressed circRNAs (5 up-regulated and 11 down-regulated circRNAs) between exo-PCOS and exo-control, including 3 annotated exonic circRNAs and 13 novel ones. Clustering analysis based on the differentially expressed circRNAs clustered the exo-PCOS and the exo-control groups (control). Conclusion: the circRNA expression profile of exosome derived from follicular fluid of five PCOS and five control patients were determined by RNA sequencing technology. 16 circRNAs showed significantly different expression in the exosome of PCOS FF. GO and KEGG pathway analysis indicated that the parental genes of the candidate circRNAs were involved in ovarian steroidogenesis, aldosterone synthesis and secretion, thyroid hormone signaling pathway, ubiquitin mediated proteolysis, Jak-STAT signaling pathway, and endocytosis pathway.

Project description:Polycystic ovary syndrome (PCOS), the most common cause of anovulatory infertility, is characterized by increased ovarian androgen production, arrested follicle development, and is frequently associated with insulin resistance. These PCOS phenotypes are associated with exaggerated ovarian responsiveness to FSH and increased pregnancy loss. To examine whether the perturbations in follicle growth and the intrafollicular environment affects development of the mature PCOS oocyte, genes that are differentially expressed in PCOS compared to normal oocytes were defined using microarray analysis. This analysis detected approximately 8000 transcripts. Hierarchical clustering and principal component analysis revealed differences in global gene expression profiles between normal and PCOS oocytes. 374 genes had a statistically-significant increase or decrease in mRNA abundance in PCOS oocytes. A subset of these genes was associated with chromosome alignment and segregation during mitosis and/or meiosis, suggesting that increased mRNAs for these proteins may negatively affect oocyte maturation and/or early embryonic development. Of the 374 differentially expressed genes, 68 contained putative androgen receptor, retinoic acid receptor, and/or peroxisome proliferating receptor gamma binding sites, including 9 of the genes involved in chromosome alignment and segregation. These analyses demonstrated that normal and PCOS oocytes that are morphologically indistinguishable and of high quality exhibit different gene expression profiles. Furthermore, altered mRNA levels in the PCOS oocyte may contribute to defects in meiosis and/or mitosis which might impair oocyte competence for early development and therefore contribute to poor pregnancy outcome in PCOS.

Project description:Polycystic ovary syndrome (PCOS) is a heterogeneous endocrine disorder characterized by hyperandrogenism, ovulatory dysfunction, and polycystic ovaries. In this study, we induced a PCOS rat model by oral administration of letrozole combined with a high-fat diet and then treated with mogroside V (MV) to evaluate the protective roles on endocrine and follicle development in PCOS rats and the underlying mechanisms. Purpose: To detect the difference of ovary transcriptome profiling between PCOS model and Control rat and to evaluate the effect of mogroside V on the transcriptome profiling of ovaries of PCOS model rats. Methods: Ovarian mRNA profiles of 15-week-old Control, PCOS and PCOS-MV group rats (4 rats per group) were generated by deep sequencing,using Illumina PE150.

Project description:Polycystic ovary syndrome (PCOS) is typically characterized by oligo or anovulation, hyperandrogenism and polycystic ovarian morphology, affecting 5-20% of women of reproductive age [1]. It has drawn significant attention as a major cause of anovulatory infertility and the syndrome of metabolic, reproductive and obstetrical disorders [2 ,+]. Due to heterogeneous clinical features and unclear pathogenesis of PCOS, the diagnosis and treatment strategies remain a matter of debate. To better understand the complex follicular development environment in PCOS, we conducted a TMT-based quantitative proteomic study to compare the composition of proteins, pathways and molecular functions of FF from lean and overweight/obese women with PCOS and that of healthy controls.
