Project description:The hypothesis that male michrochimerism in eutopic endometrium is a factor for endometriosis, as indicated by indirect evidence was examined in endometrial samples from control (Group 1) and stage IV ovarian endometriosis (Group 2), either fertile (Group 1A and 2A) or Infertile (Group 1B and 2B) pateints. 6 coding and 10 non-coding genes showed bi-modal pattern of expression characterised by low expression in samples obtained from fertile patients and high expressions in infertile patients. Several coding and non-coding MSY-linked genes displayed michrochimerism in form of presence of their respective DNA inserts along with their microarray-detectable expression in endometrium irrespective of fertility history and disease.
Project description:This SuperSeries is composed of the following subset Series:; GSE11691: Euctopic and ectopic human endometrium (endometriosis); GSE11768: Nude mouse model of endometriosis Experiment Overall Design: Refer to individual Series
Project description:We performed RNA-seq on RNA samples of organoids derived from healthy, eutopic (endometrium of patients with endometriosis) and ectopic (endometriosis) endometrium
Project description:Endometriosis is defined as the presence of endometrial tissue (eutopic tissue) outside the uterus (ectopic tissue). We assessed differentially expressed microRNAs in ectopic endometrium compared with eutopic endometrium. Comparison of paired eutopic/ectopic endometrium microRNAs from three patients.
Project description:Transcriptome profiles were investigated in isolated endometrial stromal cells (ESCs) from eutopic and ectopic endometrium. The profiles were quite different between eutopic ESC and ectopic ESC, whereas no clear dfference was recognized between eutopic ESC with and without endometriosis. Total RNA from three cultured endometrial stromal cells (ESCs) from eutopic endometria without endometriosis, three ESCs with endometriosis and three ESCs from chocolate cysts were hybridised to the Affymetrix Human Gene 1.0 ST Array.
Project description:Endometriosis is defined as the presence of endometrial tissue (eutopic tissue) outside the uterus (ectopic tissue). We assessed differentially expressed microRNAs in ectopic endometrium compared with eutopic endometrium.
Project description:Adenomyosis, defined as ectopic endometrial tissue within the myometrium, can often be misdiagnosed as multiple uterine leiomyomata or endometrial thickening. We therefore performed a combined mRNA and long noncoding (lnc)RNA microarray and bioinformatic analysis of eutopic and ectopic endometrium in women with adenomyosis to better understand its pathogenesis and help in the development of a semi-invasive diagnostic test. A total of 586 mRNAs were increased and 305 mRNAs decreased in ectopic endometrium of adenomyosis compared with eutopic endometrium, while 388 lncRNA transcripts were up-regulated and 188 down-regulated in ectopic compared with paired eutopic endometrial tissue. Bioinformatic analysis suggested a series of metabolic and molecular abnormalities in adenomyosis, which have many similarities with endometriosis. Furthermore, our study constitutes the first known report of lncRNA expression patterns in human adenomyosis ectopic and eutopic endometrial tissue. Two-condition experiment, ectopic endometrium vs. eutopic endometrium. 3 samples,self-control
Project description:Endometriosis is a complex pathological condition in which multiple components are involved in the disease development and clinical outcome. Endometriosis is mainly an inflammatory codition estrogen-dependent, with unknown pathogenesis, that is characterized by dissemination of edometrium tissue in ectopic position (ovary or pelvic peritoneum). Two main theories rise the pathologic onset: the presence of retrograde menstruation and celomic metaplasia in the pelvic peritoneum, that can occur for development defects. Endometriosis is related not only to genetic or immunological changes and to environmental pollution factors, as the endocrine interferents. The disease phenotype results from multiple events (genetics and enviromental), thus it is difficult to find a single gene as causative while is more probable that a gene network/s might involved in the onset and mantainement of the disease state. The peculiarity of endometriosis rely on the tissue speificity manteinance in the ectopic position, where it responds to the hormone stimuli as the tissue in the eutopic position. In order to identify genes potentially involved in growth and mainteinance of the ectopic endometrium, we have profiled ectopic (8 samples) and eutopic endometrium (8 samples) from several affected woman in the proliferative phase. As control we used endometrium from normal health donors in the same phase (6 samples).
