Induction of insulin gene transcription by Gli-similar KrÃ¼ppel-like zinc finger protein 3, Glis3, in Î±TC1-9 cells

ABSTRACT: In this study, we examined the effect of Glis3 on the transcriptional activation of gene expression, including insulin gene, in pancreatic Î±-cell line, Î±TC1-9, which do not express the insulin gene. We demonstrate that Glis3 induces the transcription of the insulin and identified a number of other genes that are induced by Glis3. Using ChIP-Seq we map the genome-wide sites with which Glis3 is associated. From this the consesus Glis3 binding site was calculated. This study shows that Glis3 is recruited to the proximal promoter of the insuln gene inthe pancreatic Î±-cell line, Î±TC1-9.

Chip-Seq analysis of human chromosome 21 after its passage through either the female or male mouse germline

Project description:This study aims to investigate whether the passage of human chromosome 21 through the mouse male germline results in changes in the transcriptional deployment of the exogenous chromosome in the offspring generation. We used the Tc1 mouse model that stably carries almost an entire copy of human chromosome 21 and profiled the genome-wide pattern of H3K4me3, H3K27ac, CEBPA, HNF4A and RNA polymerase II in liver tissue of male and female-germline derived Tc1 mice using ChIP-Seq. Furthermore, the genome-wide pattern of H3K4me3 was profiled in additional tissues including kidney, liver and brain.

Epigenetic comparison of human DNA in specific human tissues to human DNA in transgenic mouse tissues

Project description:This project aims to study human repetitive elements on human chromosome 21 (HsChr21) in a heterologous mouse environment (Tc1 mouse). The in vivo, HsChr21-wide enrichment of active histone modified regions (H3K4me3) and transcription factor binding sites was profiled by ChIP-seq in Human and Tc1 mouse tissue in order to determine the unbiased regulation of the human genome.

Glis3 regulates pancreatic beta cells development and maturation

Project description:Glis3 is expressed in pancreatic beta and PP cells. To identify down stream target genes of Glis3, we performed microarray analysis using pancreas total RNAs from 1 week-old WT and Glis3KO2 mice. insulin and pancreatic polypeptide (Ppy) was significantly decreased together with several other Î² cell markers, Glut2 and MafA by microarray analysis. Immunohistochemistry, QRT-PCR, and transmission electron microscopy indicated that postnatal Glis3KO2 pancreas still contains a large population of Î² cells that express Pdx-1, Nkx6.1, and Isl-1; however, insulin production and secretory granules were greatly reduced in these cells. In addition, chromogranin A (ChgA) and Urocortin 3, which are associated with mature Î² cells, was dramatically decreased in Glis3KO2 pancreas. These observations suggest that Glis3 plays a critical role in the maturation of pancreatic Î² cell phenotype. Pancreatic total RNAs were purified from 4 WT and 4 Glis3KO2 at 1 week old age. Then the samples were applied to Agilent mouse genome chip.

Methylation profiling by array of human and TC1 and TC0 mouse strain livers and testes to study human repetitive elements on human chromosome 21 in a heterologous mouse environment

Project description:The aim of this project is to study human repetitive elements on human chromosome 21 in a heterologous mouse environment (Tc1 mouse). To determine the unbiased regulation of the human genome, suppressed regions of human chromosome 21 were identified in vivo in liver and testes of human and Tc1 mouse by Illumina Infinium HumanMethylation450k beadrray. The complementary dataset characterising activated chromosomal regions (H3K4me3) and transcription factor binding sites profiled by ChIP-seq is available under accession E-MTAB-1104.

Single-cell RNA sequencing of mouse germ cells

Project description:Spermatogenesis is a recurring differentiation process that results in the production of male gametes within the testes. During this process, spermatogonial stem cells differentiate to form spermatocytes, which undergo two rounds of meiotic division to form haploid spermatids. Throughout spermiogenesis, round spermatids elongate to form mature sperm. To profile maturing germ cells during the first wave of spermatogenesis, we generated droplet-based single cell RNAseq from juvenile animals at post-natal day P5-P35 as well as adult animals. Cells were isolated from whole testes. Furthermore, to assay the robustness of the meiotic cell division process, we profiled germ cells of the trans-chromosomal mouse model (Tc1) that carries a copy of the human chromosome 21.

BioCAP-Seq analysis of human chromosome 21 after its passage through either the mouse male germline

Project description:This study aims to investigate whether the passage of human chromosome 21 through the mouse male germline results in changes in the transcriptional deployment of the exogenous chromosome in the offspring generation. We used the Tc1 mouse model that stably carries almost an entire copy of human chromosome 21 and profiled the genome-wide pattern of non-methylated DNA using BioCAP-sequencing (doi: 10.1093/nar/gkr1207) in the livers of male- and female-germline derived Tc1 mice. This dataset contains only the samples for male-germline derived animals, BioCAP-Seq data for female-germline derived animals have already been deposited in Gene Expression Omnibus with the accession number GSE72208.

Histone-fold domain protein NF-Y promotes chromatin accessibility for cell type-specific master transcription factors [ChIP-seq]

Project description:Cell type-specific master transcription factors (MTFs) play vital roles in defining cell identity and function. However, the roles ubiquitous factors play in the specification of cell identity remain underappreciated. Here we show that all three subunits of the ubiquitous heterotrimeric CCAAT-binding NF-Y complex are required for the maintenance of embryonic stem cell (ESC) identity, and establish NF-Y as a novel component of the core pluripotency network. Genome-wide occupancy and transcriptomic analyses in ESCs and neurons reveal that not only does NF-Y regulate genes with housekeeping functions through cell type-invariant promoter-proximal binding, but also genes required for cell identity by binding to cell type-specific enhancers with MTFs. Mechanistically, NF-Y's distinctive DNA-binding mode promotes MTF binding at enhancers by facilitating a permissive chromatin conformation. Our studies unearth a novel function for NF-Y in promoting chromatin accessibility, and suggest that other proteins with analogous structural and DNA-binding properties may function in similar ways. Genome-wide mapping of NF-YA, NF-YB, and NF-YC subunits of the NF-Y complex in mouse ESCs, and microarray gene expression profiling of control knockdown (KD), NF-YA KD, NF-YB KD, NF-YC KD, and NF-YA/NF-YB/NF-YC triple KD ESCs.

TGF-Î² Tumor Suppression Through A Lethal EMT

Project description:TGF-Î² is a major tumor suppressor in gastrointestinal (GI) and squamous carcinomas, which exhibit frequent genetic inactivation of Smad4, a key TGF-Î² signaling component. Apoptosis is implicated as an important mediator of the tumor suppressive function of TGF-Î², although this process remains poorly understood. To address this long-standing question, we dissected the tumor suppressive action of TGF-Î² in naÃ¯ve pancreatic ductal adenocarcinoma (PDA) cells. Here we show that TGF-Î²/Smad4 signaling triggers an EMT in Kras-mutant pancreatic progenitor cells but turns this process into a trigger of apoptosis by converting the progenitor cell transcription factor Sox4 from an enforcer of epithelial progenitor identity into an activator of apoptosis. This occurs as a result of the EMT-linked repression of the endodermal master regulator Klf5, which cooperates with Sox4 to promote epithelial progenitor identity, and loss of which unmasks a latent apoptotic transcriptional program driven by Sox4. By losing Smad4, Kras-mutant PDA cells avoid this fate and instead use Sox4 as a TGF-Î²-dependent enforcer of the epithelial progenitor cell state. In this study, 16 RNA-Seq samples and 6 ChIP-Seq samples are included.
