(Submitter supplied) In this study, to identify the target genes of PWRN2, we first constructed lentivirus shRNA vectors to infect the KGN cell lines to gain three KGN/shPWRN2 cell lines with down-regulated PWRN2 expression levels. Then, the expression profiles of mRNAs and lncRNAs in KGN/shPWRN2 cells were determined by microarray. The results revealed thousands of lncRNAs and mRNAs expressed in KGN/shPWRN2. The expression of 176 lncRNAs significantly changed in KGN/shPWRN2 cell lines relative to control NC cell lines. more...

(Submitter supplied) 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. more...

(Submitter supplied) 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. more...

(Submitter supplied) Polycystic ovary syndrome (PCOS) is a common endocrine and metabolic disorder that is characterized by increased circulating androgen levels, anovulatory infertility, and frequently, insulin resistance and hyperinsulinemia.The abnormity of oocyte nuclear maturity is the main reason for anovulatory infertility and pregnancy loss in PCOS patients.The bidirectional exchanges between oocyte and contiguous CCs are important for oocyte competence acquisition, early embryonic development and CC expansion.Gene expression profiles of CCs has been suggested to predict embryo development and pregnancy outcome. more...

(Submitter supplied) Aberration in miRNA expression or DNA methylation is a causal factor for numerous pathological conditions including polycystic ovarian syndrome PCOS, a common endocrine disorders and leading cause of infertility. The epigenetic interactions between miRNA and DNA methylation remain unexplored in PCOS. Our study identifies epigenetic alternation in ovarian granulosa cells from PCOS patients and helps to reveal the pathogenesis of PCOS.

(Submitter supplied) Cumulus cells are biologically distinct from other follicular cells and perform specialized roles, transmitting signals within the ovary and supporting oocyte maturation during follicular development. The bi-directional communication between the oocyte and the surrounding cumulus cells is crucial for the acquisition of oocyte competence. Using Illumina/deep-sequencing technology, we dissected the small RNAome of pooled human mature MII oocytes and cumulus cells.

(Submitter supplied) 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. more...
