Integrating ATAC-seq and RNA-seq reveals tissue-specific genes and repressed networks in the placenta

ABSTRACT: We performed ATAC-seq on placenta dissected from e9.5 timed-pregnant mice in order to generate genome-wide chromatin accessibility maps. Integrating this data with previously published RNA-seq data showed that: 1) genes that have high expression and high ATAC-seq read coverage at the transcription start site (TSS) were enriched for house-keeping functions; 2) genes that have high expression and medium-low coverage at the TSS were enriched for placenta-specific genes and functions; 3) genes that have low expression and high TSS coverage are actively repressed. From the actively repressed genes, we extracted a protein-protein interaction network enriched for neuronal functions. These data increase our understanding of active and repressed gene networks in the e9.5 placenta. The analysis also provides a method for identifying repressed networks and tissue-specific genes by integrating ATAC-seq and RNA-seq data. Please note that the RNA-Seq data are already deposited and available under GSE65808.

The regulatory role of ZEB2 in ABC formation

Project description:To elucidate the direct targets of ZEB2 in ABCs, we performed high-throughput sequencing of regulome by ATAC-seq, CUT & Tag, and CUT & RUN, leading to the identification the accessible sites with ZEB2 binding. Among the genes differentially expressed by Zeb2 deficiency, we found 33 candidate target genes of ZEB2, with 22 repressed and 11 activated by ZEB2. The critical transcription factor Mef2b, essential for GC development, was repressed by ZEB2. This direct regulation was mapped to a conserved region about 20kb downstream of Mef2b's exon I TSS, enriched with enhancer-associated features in both human and mouse.

Transcriptomic analyses identifies novel regulators of placental development

Project description:The placenta is a transient organ that is repsonsible for multiple processes during pregnancy. Here we aim to study the development of the placenta using mouse models at embryonic day (e) e7.5, e8.5 and e9.5 by integrating RNA-seq data at the three timepoints to identify important genes, inferring their interaction networks, and predict novel regulators of placental development.

Characteristic bimodal profiles of RNA polymerase II at thousands of active mammalian promoters

Project description:Here, we present PolII binding profiles from high-coverage ChIP-seq on promoters of actively transcribed genes in mouse and humans. We show that the enrichment of PolII near transcription start sites exhibits a stereotypical bimodal structure, with one peak near active transcription start sites and a second peak 110 base pairs downstream from the first.

Differential open chromatin profile and transcriptomic signature define depot-specific human subcutaneous preadipocytes [ATAC-Seq]

Project description:RNA-seq experiments revealed an A-fat and GF-fat selective gene expression signature, with 126 genes up-regulated in abdominal preadipocytes and 90 genes up-regulated in GF cells. Assay for transposase-accessible chromatin with high throughput sequencing (ATAC-seq) identified almost 10-times more A-specific chromatin-accessible regions. Using a combined analysis of ATAC-seq and global gene expression data, we identified 74 of the 126 abdominal-specific genes (59%) with A-specific accessible chromatin sites within 200kb of the transcription start site (TSS). Interestingly, only 14 of the 90 GF-specific genes (15%) had GF-specific accessible chromatin sites within 200kb of the corresponding TSS, whereas 25 of them (28%) had abdominal-specific accessible chromatin sites.

Blimp1/Prdm1 governs terminal differentiation of endovascular trophoblast giant cells and defines multipotent progenitors in the developing placenta

Project description:Expression profiling of Prdm1 mutant E9.5 placenta was performed using Illumina whole genome V2 arrays. The hypothesis tested in the present study was that Blimp1 regulates the transcription of key genes involved in trophoblast differentiation. We demonstrate that the invading SpA-TGCs display robust Blimp1 expression and Blimp1 functional loss selectively disrupts specification of this discrete TGC sub-type. Transcriptional profiling experiments identified additional SpA-TGC lineage restricted marker genes that potentially regulate placental morphogenesis. Prdm1BEH/+ (Vincent et al., 2005) animals were intercrossed to generate null placental tissue. Total RNA obtained from 10 Prdm1+/+ and 11 Prdm1-/- E9.5 placenta samples was hybridized to Illumina WG6_V2 beadchips.

Genome-scale transcription-translation mapping reveals features of Zymomonas mobilis transcription units and promoters

Project description:Limited functional annotation of the Z. mobilis genome is a current barrier to both basic studies of Z. mobilis and its development as a synthetic-biology chassis. To gain insight, we collected sample-matched multiomics data including RNA-seq, transcription start site sequencing (TSS-seq), termination sequencing (term-seq), ribosome profiling, and label-free shotgun proteomic mass spectrometry across different growth conditions to improve annotation and assign functional sites in the Z. mobilis genome. Proteomics and ribosome profiling informed revisions of protein-coding genes, which included 44 start codon changes and 42 added proteins.
