The goal of this study was to asses genome wide cross talk between Glucocorticoid Receptor (GR) and Peroxisome Proliferator Activated Receptor Alpha (PPARA) on the level of DNA binding (ChIP-seq) and gene expression (RNA-seq) in primary mouse hepatocytes.

View SamplesCurrent evidence suggests that more than half of the mammalian genome is transcribed, yet how this vast transcriptome is regulated in vivo remains poorly understood. We demonstrate here an integrated, straightforward and widely applicable approach to characterize cell type-specific transcriptional programs and regulatory mechanisms by generating two genome-wide data sets. We used deep sequencing of nuclear RNA (nucRNA-Seq) to comprehensively describe the nuclear transcriptome in ex vivo murine erythroid cells. In parallel, we generated a profile of active RNA polymerase II (RNAPII) binding by chromatin-immunoprecipitation (ChIP-Seq), allowing us to explore the relationship between RNAPII occupancy and transcriptional output in erythroid cells on a genome-wide scale. Comparative analysis of both data sets enables us to not only measure primary transcriptional output and identify genes associated with more efficient polymerase usage, but also to identify putative regulatory elements such as enhancers and novel non-coding transcripts. Application of this method to different cell types allows for the characterization of important aspects of gene regulation in a cell type-specific manner. Our findings demonstrate the complex ways in which RNAPII is associated with the genome and how this affects transcription of target genes, highlighting the importance of approaching transcriptome characterization from multiple angles.

View SamplesMouse hair follicles contain distinct epidermal stem cell populations that reside in their own microenvironments. To understand their molecular identities and surrounding microenvironments, each stem cell compartment was isolated from several different eGFP reporter mouse lines by FACS and their transcriptome data was obtained by RNA sequencing.

View SamplesEven after decades of living in the same laboratory environment two Drosophila melanogaster strains originating from North America (Canton-S) and Central Russia (D18) demonstrate a few differentially expressed genes some of which may be important for local adaptation (e.g. genes responsible for insecticide resistance). Genes with different level of expression between Canton-S and D18 strains belong to important metabolic pathways, for instance energy metabolism, carbohydrate metabolic process, locomotion, body temperature rhythm regulation and tracheal network architecture.

View SamplesExpansion for hematopoietic cells from umbilical cord blood is a strategy for use this cell source in clinic transplants, however, it is important to know about the genomic changes that can occur in expanded cells. In order to detect global expression profiles changes in hematopoietic stem and progenitors cells generated in vitro, we analyzed hematopoietics populations obtained by FACS in fresh from umbilical cord blood. HSC (fHSC) was defined as CD34+ CD38- CD71- CD45RA- Lin- and were cocultured with stromal cell line OP-9 plus FL, SCF, IL3, IL6, TPO, GMCSF and G-CSF by 7 days, after time we repurified HSC population by FACS using same immunophenotype (ivHSC). In other hand, fresh erythroid progenitors cells (fEPC) were identified as CD34+CD38+CD71+CD45RA- Lin- and fresh myeloid progenitors cells (fMPC) were identified as CD34+CD38+CD71-CD45RA+Lin-. In vitro progenitors cells (ivEPC and ivMPC) were obtained by culturing fHSC in Stemspan serum-free media plus SCF, TPO, IL6, FL and IL3 by 10 days, after time cells were repurified by FACS using same immunophenotype for fresh progenitors. In vitro generated cells were compared with their corresponding fresh population cells.
