High-throughput lncRNA sequencing profile of ovarian granulosa cells in polycystic ovary syndrome

ABSTRACT: Purpose:To examine different expression profiles of lncRNAs and mRNAs in ovarian granulosa cells (GCs) in PCOS patients and controls Patients:6 GCs samples in each group were subjected to high-thoughput sequencing Results:54,615 lncRNAs and 123,141 mRNAs were detected in this high-thoughput sequencing, and we identified 1049 differential expressed lncRNAs and 3246 mRNAs (fold-change≧2, P-value<0.05). So far, we found 7 lncRNAs and 3mRNAs were validated consistent with sequence profile which were selected, randomly. There is still a large part that we have not verified yet. Conclusion: Our study provides the detail analysis of GCs transcriptomes, generated by high-thoughput technology. This report also provides a framework for comparative investigations of PCOS. Our results revealed the expression of lncRNAs, mRNAs and part of circRNAs in PCOS, after more in-depth research in future, it can provide basic datas for studying the pathogenesis of PCOS.

Multiomics analysis reveals molecular abnormalities in granulosa cells of women with polycystic ovary syndrome

Project description:Polycystic ovary syndrome (PCOS) is the most common complex endocrine and metabolic disease in women of reproductive age. It is characterized by anovulatory infertility, hormone disorders, and polycystic ovarian morphology. Regarding the importance of granulosa cells (GCs) in the pathogenesis of PCOS, few studies have investigated the etiology at a single “omics” level, such as with an mRNA expression array or methylation profiling assay, but this can provide only limited insights into the biological mechanisms. Here, genome-wide DNA methylation together with lncRNA-miRNA-mRNA profiles were simultaneously detected in GCs of PCOS cases and controls. A total of 3579 lncRNAs, 49 miRNAs, 669 mRNAs, and 890 differentially methylated regions (DMR)-associated genes were differentially expressed between PCOS cases and controls. Pathway analysis indicated that these differentially expressed genes were commonly associated with steroid biosynthesis and metabolism-related signaling, such as glycolysis/gluconeogenesis. In addition, we constructed ceRNA networks and identified some known ceRNA axes, such as lncRNAs-miR-628-5p-CYP11A1/HSD17B7. We also identified many new ceRNA axes, such as lncRNAs-miR-483-5p-GOT2. Interestingly, most ceRNA axes were also closely related to steroid biosynthesis and metabolic pathways. These findings suggest that it is important to systematically consider the role of reproductive and metabolic genes in the pathogenesis of PCOS.

IGF2BP2-regulated alternative splicing of NFIC causes excessive granulosa cell proliferation in PCOS [IRIP-seq]

Project description:The expression of IGF2BP2 in GCs from PCOS patients was detected using RT-qPCR and western blot. We captured IGF2BP2-interacting transcripts, global transcriptome together with alternative splicing by RNA immunoprecipitation sequencing (RIP-seq) and RNA sequencing (RNA-seq). KGN cells transfected with IGF2BP2 overexpressing plasmids and nuclear factor 1 C-type (NFIC) siRNAs, were applied to CCK-8, EdU and TUNEL assays. IGF2BP2 was highly expressed in GCs from PCOS patients. As a RBP, it preferentially bound to the 3’and 5’UTRs of mRNAs with GGAC motif and a newly found GAAG motif. The overexpression of IGF2BP2 changed the transcriptome profile of KGN cells. IGF2BP2 functioned to regulate alternative splicing events (ASEs) and promote cell proliferation through inhibiting exon skipping events of NFIC. In conclusion, we demonstrated that IGF2BP2 promotes granulosa cell proliferation via regulating alternative splicing of NFIC in PCOS. The findings help to better understand the roles of IGF2BP2 in the pathogenesis of PCOS.

Aberrant expression of long noncoding RNAs in exosomes in follicle fluid from PCOS patients

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.

Enhanced Inflammatory Transcriptome in the Granulosa Cells of Women With Polycystic Ovarian Syndrome

Project description:Context: Polycystic ovarian syndrome (PCOS), the most common endocrine disorder of reproductive- aged women, is associated with systemic low-grade inflammation. Objective: We propose that increased or altered intrafollicular inflammatory reactions also occur in periovulatory follicles of PCOS patients. Design: Gene profiling and quantitative PCR (qPCR) analyses in granulosa-lutein cells (GCs) collected from PCOS and non-PCOS women undergoing in vitro fertilization were compared with serum and follicular fluid (FF) levels of cytokines and chemokines. Setting: This was a university-based study. Patients: Twenty-one PCOS and 45 control patients were recruited: demographic, hormone, body mass index, and pregnancy outcomes were abstracted from patient data files. Interventions:GCcytokine/chemokinemRNAswere identified and analyzed by gene-chip microarrays/ qPCR before and after culture withhumanchorionic gonadotropin, DHT, IL-6, or IL-8; serum/FF cytokine levels were also analyzed. Main Outcome Measures: Relative serum/FF cytokine levels and GC cytokine expression before and after culture were compared and related to body mass index. Results: The following results were found: 1) PCOS GCs express elevated transcripts encoding cytokines, chemokines, and immune cell markers, 2) based on gene profiling and qPCR analyses, obese PCOS patients define a distinct PCOS disease subtype with the most dramatic increases in proinflammatory and immune-related factors, and 3) human chorionic gonadotropin and DHT increased cytokine production in cultured GCs, whereas cytokines augmented cytokine and vascular genes, indicating that hyperandrogenism/elevated LH and obesity in PCOS women augment intrafollicular cytokine production. Conclusions: Intrafollicular androgens and cytokines likely comprise a local regulatory loop that impacts GC expression of cytokines and chemokines and the presence of immune cells; this loop is further enhanced in the obese PCOS subtype.

LncRNAs expression signatures of cumulus cells isolated from PCOS patients revealed by microarray

Project description:Our study is the first one to determine genome-wide lncRNAs expression patterns in cumulus cells of PCOS patients by microarray. The results displayed that clusters of lncRNAs (n=623) were aberrantly expressed in PCOS patients compared with non-PCOS patients. Many differentially expressed lncRNAs were transcribed from regions on chromosome 2 and classified into enhancer-like lncRNA subgroup. XLOC_011402 (PWRN2) was found for the first time that it was not only expressed in testis but also in cumulus cells. All the results revealed that lncRNAs differentially expressed in cumulus cells may exert a partial or key role in hormone abnormalities of PCOS patients and maybe impact on oocyte development. Taken together, this study may provide potential targets for further treatment of PCOS and novel insights into oocyte development.
