Gene expression profiling of leiomyoma and myometrium specimens collected at distinct phases of the menstrual cycle

ABSTRACT: Despite progesterone’s key role in uterine smooth muscle tumorigenesis, the mechanisms by which it promotes the growth of uterine leiomyomas remain poorly understood. The aim of this study was to identify novel gene products mediating progesterone’s effects in uterine leiomyomas. Gene expression profiling was used to identify putative progesterone-regulated genes differentially expressed in uterine leiomyomas, which were then studied in vitro. Our analyses identified secreted frizzled-related protein 4 (sFRP4) as a key gene product functionally linked to PR activation whose expression was a) 2.6-fold higher in leiomyomas than myometrium (n=26, p<0.01) and b) 2.5-fold higher during the proliferative phase of the menstrual cycle (n=26, p<0.01).

Epigenome analysis of uterin leiomyoma and myometrium with or without leiomyoma [Methylation data]

Project description:Profiles of genome-wide DNA methylation were investigated in leiomyomas and in myometrium with and without leiomyomas. Profiles of DNA methylation in the myometrium with and without leiomyomas were quite similar while those in leiomyomas were distinct. Bisulphite converted DNA from the three uterine leiomyoma, three myometrium with leiomyoma and three myometrium without leiomyoma were hybridised to the Illumina infinium HumanMethylation450 BeadChip.

Transcription profiling of human uterine fibroid (leiomyoma) and normal myometrial tissue to identify differentially expressed genes

Project description:Our study seeks to identify genes differentially expressed between uterine leiomyomas and normal myometrial tissue. This series consists of samples derived from normal myometrium and uterine leiomyomas obtained from fibroid afflicted patients.Total RNA was extracted from samples, converted to biotin-labeled cRNA, hybridized to oligonucleotide arrays, and followed by model based expression analysis.,In order to select differentially expressed genes of interest, dChip model-based expression analysis was employed. Significant genes were identified, utilizing the dChip software, as having an average fold change of > +1.5 or < -1.5 between leiomyoma and normal myometrium and p < 0.05. Under these conditions the 226 genes in the following list were identified.

Genome-wide chromatin interaction maps of enhancer-promoter and promoter-promoter contacts in 5 leiomyoma (MED12 G44 mutant) and 5 matched normal myometrium (WT) patient tissue samples.

Project description:Through promoter capture Hi-C performed directly from patient tissue samples, we report the near-native characterization of intradomain chromatin architecture changes in uterine leiomyomas. This study identifies altered enhancer-promoter interactions and differential enhancer usage of enhancers associated with extracellular matrix-associated genes.

Profiling of Myometrium and Leiomyoma transcriptomes in 15 leiomyoma (MED12 G44 mutant) and 15 matched normal myometrium (WT) patient tissue samples.

Project description:Through comprehensive profiling of transcribed genes in myometrium and leiomyoma tissue samples, we demonstrate two distinct gene expression profiles for myometrium and leiomyoma. This study shows that transcriptional dysregulation, and not post-transcriptional dysregulation, is primarily responsible for the perturbations of key biological processes in leiomyomas such as the extracellular matrix organization.

Expression profiling of lncRNAs, miRNAs and mRNAs and their differential expression in leiomyoma using next generation RNA sequencing

Project description:Total RNA was isolated from leiomyoma and paired myometrium (N=8) and samples from three pairs were subjected to RNA sequencing. After analysis, 5941 lncRNAs (2813 up- and 3128 down-regulated at ≥1.5 fold), 148 miRNAs (56 up- and 96 down-regulated at ≥1.5 fold) and 3855 mRNAs (2030 up- and 1855 down-regulated at ≥1.5 fold) were differentially expressed in leiomyomas. Using QRT-PCR we further confirmed the expression of HULC, lnc-MEG3, LINC00890, TSIX, LINC00473, lnc-KLF9-1 and lnc-POTEM-3 (lncRNA-ATB) in leiomyoma and matched myometrium (N=8). Our results presented here provide a comprehensive expression profile of lncRNAs in leiomyomas with concurrent integrated expression of miRNAs and mRNAs in leiomyomas.

Project description:Gene expression profiles of 10 uterine leiomyomas and their matched normal myometrium specimens were studied using Affymetrix GeneChip Human Genome U133 Plus 2.0 gene expression arrays. Four tumors displayed a codon 44 mutation, four carried a intron 1 mutation, and the remaining two displayed no MED12 mutation.
