Genome-wide long non-coding RNAs and mRNAs analysis of the tissues related to ovarian endometriosis

ABSTRACT: To investigate the function of long non-coding RNA (lncRNA) in ovarian endometriosis and explore its pathogenesis from a new prospective pathway, we conducted genome-wide microarray expression profiling.GO and KEGG analysis demonstrated that the differential mRNAs in ECvsEU and NOvsEU mostly focused on cell adhesion and biological adhesion pathways, nevertheless ECvsNO on molecular metabolism pathways. CHL1 was the most up-regulated mRNA in EC than EU, and the expression of its two antisense lncRNAs, CHL1-AS1 and CHL1-AS2 exhibited the same tendency. They were significantly correlated with each other through bioinformatic calculation.GSEA analysis revealed that CHL1-AS1 and CHL1-AS2 were conspicuously concerned with the same gene set. Validated by qRT-PCR, CHL1-AS2 was higher expressed in EC than EU. It was also up-regulated in NO, and the relative fold changes in EC/EU and NO/EU showed no statistical significance (P>0.05). Furthermore, the value of EC/NO was more closed to 1 when sample size was enlarged, presenting the near expression of CHL1-AS2 in EC and NO. Consequently, we supposed that CHL1, CHL1-AS1 and CHL1-AS2 may play an important part in ovarian endometriosis.

Analysis of genes regulated by AS1 and AS2

Project description:AS1 and AS2 encode MYB related protein and AS2-domain containing protein, respectively and may regulate transcription. These genes are involved in the determination of axes of leaves of Arabidopsis thaliana. To know the gene regulation in the leaf development, expression profile among wild-type, as1 and as2 mutants and AS2 overexpression plants were compaired. shoot apices from as1-1, as2-1, AS2 overexpressing, and wild type embryos

Genome-wide expression analysis of autologous eutopic and ectopic endometrium from fertile Indian women with endometriosis

Project description:Whole genome expression analyses of autologous, paired eutopic and ectopic endometrial samples obtained during proliferative and secretory phases of menstrual cycles from eighteen (n=18) fertile women suffering from confirmed stage 3 (moderate) and stage 4 (severe) ovarian endometriosis were performed using whole human genome oligo microarray Agilent paltform (Cat. No. G4112F). In the present study, genome-wide expression analysis of autologous, paired eutopic and ectopic endometrial samples obtained during proliferative (n=13) and secretory (n=5) phases of menstrual cycle from fertile women (n=18) suffering from moderate (stage 3; n=8) or severe (stage 4; n=10) endometrioma was performed by using Agilent single color oligo microarray platform (G4112, 4X44K). Thus eighteen (18) eutopic (shown as EU) and eighteen (18) ectopic (shown as EC) samples from eighteen (18) subjects with confirmed menstrual phase (proliferative and secretory) and severity stages (stage 3 and stage 4) were studied.

Analysis of genes regulated by AS2 and TOP1

Project description:AS2 encode AS2-domain containing protein and may regulate transcription. AS2 is involved in the determination of axes of leaves of Arabidopsis thaliana. Type IB DNA topoisomerase (TOP1α) gene has genetic interaction with AS1 and AS2 and is involved in repression of leaf polarity genes. To know the gene regulation in the leaf development, expression profile among wild-type and as2 mutant treated with and without 10-hydroxyl substituted camptothecin (10H-CPT), a specific TOP1 inhibitor, were compared

Transcriptomic Analyses of Ovarian Clear-Cell Carcinoma with Concurrent Endometriosis

Project description:Endometriosis, a benign inflammatory disease whereby endometrial-like tissue grows outside the uterus, is a risk factor for endometriosis-associated ovarian cancers. In particular, ovarian endometriomas, cystic lesions of deeply invasive endometriosis, are considered the precursor lesion for ovarian clear-cell carcinoma (OCCC). To explore the transcriptomic landscape, OCCC from women with pathology-proven concurrent endometriosis (n = 4) were compared to benign endometriomas (n = 4) by bulk RNA and small-RNA sequencing.

Complement Roles Revealed by Immune Gene Profiling in Endometriosis and Endometriosis-Associated Ovarian Cancer

Project description:Mechanisms of immune dysregulation against established tumors are relatively well understood. Much less is known about the role of immune effectors against cancer precursor lesions. Endometrioid and clear cell ovarian tumors may partly derive from endometriosis, a commonly diagnosed chronic inflammatory disease. We performed here the most comprehensive immune gene expression analysis of pelvic inflammation in endometriosis and endometriosis-associated ovarian cancer (EAOC). RNA was extracted from 120 paraffin tissue blocks comprising of normal endometrium (n=32), benign endometriosis (n=30), atypical endometriosis (n=15) and EAOC (n=43). Serous tumors (n=15) were included as non-endometriosis associated controls. The immune microenvironment was profiled using Nanostring and the nCounterÂ® GX Human Immunology Kit, comprising probes for a total of 511 immune genes. Please note that 3 normal endometrium samples did not pass the array quality filtering and therefore excluded in the data analyses.

Expression data from SKOV3.ip cells by knockdown RAD51-AS1 expression.

Project description:Long non-coding RNAs (lncRNA) have been shown to play crucial roles in tumorigenesis. Little is known about lncRNA RAD51-AS1 in diseases. Here, we investigated the role of RAD51-AS1 in Epithelial ovarian cancer. Silencing RAD51-AS1 inhibited proliferation through cell cycle arrest and promotion in apoptosis, both in vitro and in vivo. But the mechanism of RAD51-AS1 downstream regulation remains unclear. In order to identify the downstream regulation of RAD51-AS1 in epithelial ovarian cancer, we used antisene oligotides targeting RAD51-AS1 / negative control to transfect Skov3.ip cells. Then, we used microarrays to identified differential expression genes and to look for possible target genes by knockdown RAD51-AS1 expression.
