Project description:The human endometrium is a highly regenerative tissue that undergoes cyclical proliferation, differentiation and shedding each month. The upper functionalis layer of the endometrium is shed in response to circulating levels of estrogen and progesterone, while the lower basalis layer remains. Clonogenic epithelial stem/progenitor cells likely responsible for regenerating endometrial epithelium have been identified in pre-menopausal (Pre-M) and post-menopausal (Post-M) endometrium and may reside in the basalis layer. We undertook a transcriptional profiling of purified epithelial cells from full-thickness Pre-M and Post-M endometrium to identify differentially expressed genes. The hypothesis tested in the present study was that Post-M endometrial epithelial gene profile would be similar to the quiescent basalis epithelium of Pre-M endometrium. We found striking differential gene expression of many Wnt family members between Pre-M and Post-M and other stem cell network genes. Comparative analysis of our endometrial epithelial gene expression profiles to that of endometrial epithelial cells in remodelling endometrium also provides new evidence showing that Post-M endometrial epithelium has a similar gene signature to that of basalis epithelium of menstrual endometrium. Human endometrial tissue was obtained from 8 pre-menopausal and 3 post-menopausal women undergoing hysterectomy for various benign gynaecologic conditions. Endometrial tissue was digested and isolated using combination of DNase and collagenase. Anti-human EpCAM antibody-coated magnetic Dynabeads was used to positively select total epithelial cells from the digested single cell suspensions. Total RNA was extracted from the purified endometrial epithelial cells and hybridised to Illumina Sentrix HT12 beadchip. Resulting data was compared between pre-menopausal and post-menopausal samples.

Project description:To determine the positions of promoters and enhancers in developing Xenopus laevis epithelial progenitors, we performed ChIPseq on the histone modifications H3K4me3 and H3K27ac. We also performed ChIPseq on the transcription factors foxj1 (in the presence or absence of rfx2), myb (in the presence or absence of multicilin), and rad21. Some embryos were harvested as wild-types; in other experiments, we injected embryos with mRNAs encoding FLAG-foxj1 (with and without rfx2 morpholino) or GFP-myb (with and without an inducible form of multicilin (mcidas-HGR)). We then isolated epithelial progenitors surgically and, when injected with multicilin, induced at mid-stage 11. We then harvested chromatin at 9 hours after induction (roughly stage 18) and performed ChIPseq using antibodies against endogenous targets (H3K4me3, H3K27ac, rad21) or protein tags (FLAG, GFP). We then sequenced these libraries, aligned the reads to the X. laevis genome (version 9.1) with bwa mem and called peaks with HOMER, using input as background.

Project description:Purpose: The goals of this study are to identify AID targets in DLBCL and investigate the overlapping of AID peaks and predicted G4 forming sequences (PQS) and the B-cell super enhancer (SE) U2932 DLBCL cells obtained from the American Type Culture Collection were grown in RPMI 1640 medium (Corning) supplemented with 10% FBS (Atlanta Biiologicals) and 1% Pen/Strep (Gibco). For each immunoprecipitation reaction, 4x106 chromatin cell equivalent were incubated overnight with either an AID antibody (Abcam, ab59361) or a rabbit IgG negative control antibody, subjected to protein A/G magnetic bead binding, IP elution and DNA recovery. The ChIP DNA was used to generate ChIPseq libraries with the ChIP-Seq sample preparation kit (Illumina) for sequencing at the Arkansas Children’s Research Institute Genomics Core. The sequence reads that passed quality filters were aligned to the human genome (hg19) using BWA-MEM and peakcalled using MACS2. Results: Using an optimized data analysis workflow, we mapped about 10-20 million sequence reads per sample to the human genome (build hg19) and identified 4,573 AID peaks which were filtered out if they overlap with the mock pull-down peaks and the blacklist (ENCODE blacklisted regions). We observed the intersection of AID peaks with PQS and SEs are significantly higher than expected by chance in all cases of comparisons supporting that the number of AID peaks sharing PQS and/or SEs is not a random event. Conclusions: Sequencing analyses reveal AID targets in both activated B-cells and lymphoma are highly enriched for G4 elements and validation studies confirm a representative set of these sequences form characteristic, stable G4 structures.

Project description:In order to identify the target mRNAs of the m5C reader protein Ybx1, we carried out anti-Ybx1 RNA Immunoprecipitation(RIP) followed by RNA-sequencing to find out mRNAs that can directly bind by Ybx1. Using EZ-Magna RIPTM RNA-Binding Protein Immunoprecipitation Kit (Millipore), RNA from E13.5 wildtype mouse DRGs was pulled down by rabbit monoclonal anti-Ybx1 (abcam) and sequenced on IIIumina HiSeq3000 platform. The filtered reads were mapped to the mouse reference genome (GRCm39) using BWA mem (v 0.7.12). After peak calling using MACS2 (version 2.1.0) software, the distribution of chromosome distribution, peak width, fold enrichment, significant level and peak summit number per peak were all displayed. Fold enrichment greater than 2 was considered to be enriched. Finally, 2 biological repilicates of anti-Ybx1 RIP-seq identified 2487 transcripts. This study provides a gene list which shows mRNA binding with Ybx1 in mouse DRGs.

Project description:Up to 80% of endometrial and breast cancers express the oestrogen receptor ERa. Unlike breast cancer, anti-oestrogen therapy has had limited success in endometrial cancer, raising the possibility that oestrogen has different effects in the two cancer types. We investigated the role of oestrogen in endometrial and breast cancers using cell lines and found that oestrogen-responsive genes were predominantly unique between the two cancer types.
