Project description:Endometriotic cyst stromal cells (ECSCs) were isolated from ovarian endometriotic cyst and cultured for 48 hours in the floating three-dimensional collagen gel culture or in the conventional two-dimensional culture. Total mRNAs were extracted and subjected to gene expression microarray.
Project description:Accumulating evidences suggest that various epigenetic aberrations play definite roles in the pathogenesis of endometriosis. The aim of this study is to identify 1) the panel of aberrantly expressed genes that are epigenetically suppressed by histone acetylation in endometriosis; 2) the roles of CCAAT/enhancer-binding protein (C/EBP) alpha, one of the candidate molecules whose expression was epigenetically repressed in endometriotic cyst stromal cells (ECSCs), in the pathogenesis of endometriosis; and 3) the efficacy of the histone deacetylase inhibitors for the treatment of endometriosis. Subconfluent ECSCs cultured in 10-cm dish were further incubated for 72 h with or without VPA (8 mM) and/or 5aza. Total RNA from untreated ECSCs (n=4), VPA-treated ECSCs (n=4), 5aza-treated ECSCs (n=4), and VPA- and 5aza-treated ECSCs (n=4) was extracted and subjected to gene expression microarray analysis.

Project description:In ovarian endometrioma, much iron, which is derived from blood in cyst, deposit in stroma. This iron generates oxidative stress by Fenton reaction, which is supposed to affect endometriotic stromal cells. We used gene expression microarrays to find influence of oxidative stress on endometriotic stromal cells. Gene expression microarrays revealed no statistically differences caused by oxidative stress.
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.
