Project description:Abstract: Objective: Adenomyosis is a clinical disorder defined by the presence of endometrial glands and stroma within the myometrium, the pathogenesis of which is poorly understood. We postulate that dysregulation of genes and pathways in eutopic endometrium may predispose to ectopic implantation. No study, to our knowledge, has examined the global transcriptome of isolated eutopic endometrium from women with clinically significant adenomyosis. Design: Laboratory-based study with full IRB approval and consents. Material and Methods: Endometrial sampling was performed on hysterectomy specimens (proliferative phase) from symptomatic women with pathologically-confirmed diffuse adenomyosis (n=3). Controls (n=5) were normo-ovulatory subjects without adenomyosis. All subjects were free from leiomyoma, endometriosis, and hormonal exposures. Isolated purified total RNA was subjected to microarray analysis using the Gene 1.0 ST Affymetrix platform. Data were analyzed with GeneSpring and Ingenuity Pathway analysis. Validation of several genes was undertaken by QRT-PCR. Results: Comparison of transcriptomes of proliferative endometrium from women with and without adenomyosis revealed 140 up-regulated and 884 down-regulated genes in samples from women with adenomyosis compared to controls. Highly differentially expressed genes include those involved in regulation of apoptopsis, steroid hormone responsiveness, and proteins involved in extracellular matrix remodeling, as well as microRNAs of unknown significance. Affected canonical pathways included eukaryotic initiation factor 2 signaling, oxidative phosphorylation, mitochondrial dysfunction, estrogen receptor signaling, and mTOR signaling. Conclusions: The eutopic endometrium in patients with adenomyosis has fundamental abnormalities that may predispose to invasion and survival beyond the myometrial interface. Key Words: adenomyosis, endometrium, microarray, microRNA, endometriosis, apoptosis, signaling.

Endometrial samples from hysterectomy specimens in proliferative phase of menstrual cycle from symptomatic women with pathologically-confirmed diffuse adenomyosis were compared with endometrial samples from normo-ovulatory healthy subjects with no endometrial or uterine pathology.

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:Objective: To identify differentially expressed long noncoding RNA in the eutopic endometrium tissue of adenomyosis on a genome-wide scale. Patient(s): Seventeen women with adenomyosis and fifteen patients without adenomyosis or endometriosis receiving surgical treatment. Intervention(s): Total RNAs containing long nocoding RNAs was extracted from endometrial tissue obtained during surgery. Main Outcome Measure(s): Differentially expressed lncRNAs and mRNAs were detected by human lncRNA microarray. Result(s): We identified 165 lncRNAs and 612 mRNAs abnormally expressed (P<0.05) in the eutopic endometrium of adenomyosis. Conclusion(s): This study showed for the first time that the lncRNA expression profile was altered in women with adenomyosis.
