Project description:Retinoic acid (RA) signaling plays a major role in controlling several developmental processes in vertebrate embryos. RA repression of caudal Fgf8 has emerged as a crucial mechanism through which RA controls body axis extension, somitogenesis, and spinal cord neurogenesis. The role of RA in Fgf8 repression is supported by mechanistic studies demonstrating direct RA repression through a nearby RA response element that recruits NCOR in an RA-dependent manner. RA is also required for balanced neuromesodermal progenitor differentiation needed for coordinated generation of mesodermal progenitors for somites and neural progenitors for spinal cord. As many pathways are controlled by RA, we performed RNA-seq analysis comparing wild-type embryos with Aldh1a2 mutants that lack the ability to produce RA. This analysis identified a few hundred genes whose expression is significantly altered when RA is absent, thus providing candidate genes for further analysis to discover RA-regulated genes essential for development.

Project description:The main goal of the project is to develop a new generation of bioinformatics resources for the integrative analysis of multiple types of 'omics data. These resources include both novel statistical methodologies as well as user-friendly software implementations. STATegra methods address many aspects of the 'omics data integration problem such as the design of multi-omics experiments, integrative transcriptional and regulatory networks, integrative variable selection, data fusion, integration of public domain data, and integrative pathway analysis. To support method development STATegra uses a model biological system, namely the differentiation process of mouse pre-B-cells. The STATegra consortium generated data focused on a critical step in the differentiation of B lymphocytes, which are key components of the adaptive immune system. Transcription factors of the Ikaros family are central to the normal differentiation of B cell progenitors and their expression increases in response to developmental stage-specific signals to terminate the proliferation of B cell progenitors and to initiate their differentiation. In particular, a novel biological system that models the transition from the pre-BI stage to the pre-BII subsequent stage, where B cell progenitors undergo growth arrest and differentiation, was used. The approach involves a pre-B cell line, B3, and an inducible version of the Ikaros transcription factor, Ikaros-ERt2. Ikaros factors act to down-regulate genes that drive proliferation and to simultaneously up-regulate the expression of genes that promote the differentiation of B cell progenitors. Hence, in the B3 system, before induction of Ikaros, cells proliferate and their gene expression pattern is similar to proliferating B cell progenitors in vivo. Following Ikaros induction, B3 cells undergo gene expression changes that resemble those that occur in vivo during the transition from cycling to resting pre-B cells, followed by a marked reduction in cellular proliferation and by G1 arrest. On this system the consortium has created a high-quality data collection consisting of a replicated time course using seven different 'omics platforms: RNA-seq, miRNA-seq, ChIP-seq, DNase-seq, Methyl-seq, proteomics and metabolomics, which is used to assess and to validate STATegra methods. The STATegra experimental design consists of a 6 point time course that captures the differentiation of B3 cells containing Ikaros-ERt2 upon Ikaros induction within a 24 hr period. The process was sampled at 0, 2, 6, 12, 18, and 24 hrs respectively after Ikaros induction by Tamoxifen. As control, B3 cells transfected with an empty vector were treated and sampled in the same way as the inducible line. Eight different 'omic technologies were measured on this system: RNA-seq, miRNA-seq, DNase-seq, RRBS-seq, ChIP-seq, scRNA-seq, Proteomics and Metabolomics. Generally, three biological replicates were obtained per platform and were processed as independent batches. Metabolomics analysis was performed using 4 biological batches (7, 8, 9 and 10) and at times 0, 2, 6, 12, 18 and 24 hrs respectively. Each sample was analyzed using gas chromatography mass spectrometry (GC-MS) and liquid chromatography mass spectrometry (LC-MS).

Project description:S6K1 Knockout mice has a lean phenotype and resitant to a High Fat Diet-induced obesity (Um S.H., Nature, 2004). Adipocyte differentiation consists of two step, first, commitment from stem cell to adipocyte progenitors and second, terminal differentiation from adipocyte progenitors to mature adipocyte. We studied S6K1-dependent gene expression regulation in early stage of commitment by employing ES cell(ESC)-Embryoid Bodies(EBs) differentiation model. We established stable ES cell lines infected with either control non-silencing shRNA (shNS) or S6K1 targetting shRNA (shS6K1). Each sample was treated with retinoic acid for 3 days to induce adipogenesis, then gene expression profile was analyzed employing microarrays and up-regulated and down-regulated genes were selected for analysis. Mouse Embryoid Bodies (approximately 1000 EBs per sample) were treated with retinoic acid (1µM) for 3 days then collected for RNA extraction and hybridization on Affimetrix microarray. Two biological replicates were each performed for EBs prepared from either shNS ESCs or shS6K1 ESCs.
