mRNA expression profiles in decidualized and non-decidualized endometriotic cyst stromal cells (ECSCs).

Project description:To identify the mRNAs which regulate the decidualization of ECSCs, we explored differentially expressed mRNAs between untreated ECSCs (n=4) and decidualized ECSCs (n=4) using gene expression microarray. The mRNA expression profiles in untreated ECSCs and decidualized ECSCs were obtained, then the mRNAs were filtered by signal intensity (50.0<, at least one out of 8 samples have values within range) and flags (at least 58% of cases have good flags). We established the criteria for regulated genes: Z-score ≥2.0 and ratio ≥2.0-fold for up-regulated genes, and Z-score ≤–2.0 and ratio ≤0.5 for down-regulated genes.

miRNA expression profiles in decidualized and non-decidualized endometriotic cyst stromal cells (ECSCs).

Project description:To identify the miRNAs which regulate the decidualization of ECSCs, we explored differentially expressed miRNAs between untreated ECSCs (n=4) and decidualized ECSCs (n=4) using miRNA microarray. The miRNA expression profiles in untreated ECSCs and decidualized ECSCs were obtained, then the miRNAs were filtered by signal intensity (50.0<, at least one out of 8 samples have values within range) and flags (at least 17% of cases have good flags). We established the criteria for regulated genes: ratio ≥2.0-fold for up-regulated genes and ratio ≤0.5 for down-regulated genes.

miRNA expression profiles in endometriotic cyst stromal cells (ECSCs).

Project description:To identify the miRNAs which play a role in the development of endometriosis, we explored differentially expressed miRNAs between ECSCs (N=8) and normal endometrial stromal cells (NESCs, n=8) using miRNA microarray. The expression profiles in ECSCs and NESCs were obtained, then the miRNAs were filtered by signal intensity (20.0<, at least one out of 16 samples have values within range) and flags (at least 70% of cases have good flags). The differentially expressed miRNAs in ECSCs compared with NESCs were identified using volcano plot (Fold change >= 2.0, Mann-Whiteny U test p<0.05). The primary culture of ECSCs and NESCs (controls) were utilized. Total RNA was extracted from them, and miRNA microarray analysis was performed. The miRNAs differentially expressed between ECSCs and NESCs were identified, and aberrantly expressed miRNAs in ECSCs were defined as the endometriosis related miRNAs.

Construction of a MicroRNA-mRNA Network Underlying Decidualized Endometriotic Cyst Stromal Cells Using Bioinformatics Analysis.

Project description:Background:Decidualization of ectopic endometrium often leads to the extensive proliferation of local tissue and is easily misdiagnosed as malignant tumors. The study is aimed at constructing a microRNA- (miRNA-) mRNA network underlying decidualized endometriotic cyst stromal cells (ECSCs). Methods:All data were collected from the Gene Expression Omnibus (GEO) database. Firstly, the differentially expressed genes (DEGs, adj. P-Val < 0.05, | log FC |??1) and miRNAs (DEMs, P-Val < 0.05, ?log?FC | ?1) were analyzed by the limma package. Secondly, we predicted the target genes (TGs) of these DEMs through the TargetScan, miRDB, and miRTarBase databases. The overlapping genes between DEGs and TGs were screened out. Thirdly, the Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway and Gene Ontology (GO) enrichment analyses of the overlapping genes were performed for integrated discovery, visualization, and annotation. Then, the protein-protein interaction (PPI) network of the overlapping genes was conducted by the STRING database. Finally, we combined the PPI network and the miRNA-mRNA pairs to build a miRNA-mRNA network. Results:There are 29 DEMs and 523 DEGs. Fourteen overlapping genes were screened out, and these genes were significantly enriched in metabolism and immunity. What is more, a miRNA-mRNA network, including 14 mRNAs and 9 miRNAs, was successfully constructed. Conclusions:Taken together, the miRNA-mRNA regulatory networks described in this study may provide new insights in the decidualization of ECSCs, suggesting further investigations in novel pathogenic mechanisms.

Project description:To identify the mRNAs which regulate endomrtial decidualization, we explored differentially expressed mRNAs between untreated NESCs (n=4) and decidualized NESCs (n=4) using gene expression microarray. The mRNA expression profiles of untreated in NESCs and decidualized NESCs were obtained, then the mRNAs were filtered by signal intensity (50.0<, at least one out of 8 samples have values within range) and flags (at least 43% of cases have good flags). We established the criteria for regulated genes: Z-score ≥2.0 and ratio ≥2.0-fold for up-regulated genes, and Z-score ≤–2.0 and ratio ≤0.5 for down-regulated genes.

Endometriosis: Normal endometrial stromal cells and endometriotic stromal cells

Project description:Gene expression profiling of primary stromal cell cultures isolated from human endometrium and ovarian endometriosis. Samples are derived from the endometrium of 6 healthy patients and the endometriomas of 6 diseased patients. The results indicate the gene expression differences between these two cell populations. Stromal cells were obtained from human normal endometrial tissues and ovarian endometriomas. The tissues were digested enzymatically, and pure stromal cell populations were established.
