Description
The transcription co-factor FOG1 interacts with the chromatin remodeling complex NuRD to mediate gene activation and gene repression during hematopoiesis. We have generated mice with a targeted mutation in the endogenous Fog1 locus that results in an N-ternimal mutation in FOG1 that disrupts the interaction with NuRD.
Publication Title
FOG1 requires NuRD to promote hematopoiesis and maintain lineage fidelity within the megakaryocytic-erythroid compartment.

Description
Genome-wide mapping of transcriptional regulatory elements are essential tools for the understanding of the molecular events orchestrating self-renewal, commitment and differentiation of stem cells. We combined high-throughput identification of nascent, Pol-II-transcribed RNAs by Cap Analysis of Gene Expression (CAGE-Seq) with genome-wide profiling of histones modifications by chromatin immunoprecipitation (ChIP-seq) to map active promoters and enhancers in a model of human neural commitment, represented by embryonic stem cells (ESCs) induced to differentiate into self-renewing neuroepithelial-like stem cells (NESC). We integrated CAGE-seq, ChIP-seq and gene expression profiles to discover shared or cell-specific regulatory elements, transcription start sites and transcripts associated to the transition from pluripotent to neural-restricted stem cell. Our analysis showed that >90% of the promoters are in common between the two cell types, while approximately half of the enhancers are cell-specific and account for most of the epigenetic changes occurring during neural induction, and most likely for the modulation of the promoters to generate cell-specific gene expression programs. Interestingly, the majority of the promoters activated or up-regulated during neural induction have a bivalent histone modification signature in ESCs, suggesting that developmentally-regulated promoters are already poised for transcription in ESCs, which are apparently pre-committed to neuroectodermal differentiation. Overall, our study provide a collection of differentially used enhancers, promoters, transcription starts sites, protein-coding and non-coding RNAs in human ESCs and ESC-derived NESCs, and a broad, genome-wide description of promoter and enhancer usage and gene expression programs occurring in the transition from a pluripotent to a neural-restricted cell fate.

Description
We have looked for fusion genes in ovarian carcinomas. We combined previously known genomic aberrations, detected by karyotyping, and gene expression analysis. We found recurrent DPP9 gene expression deregulation with matching translocations. In additon, candidate fusion partner genes from the exon-level expression analysis were ranked according to deviating expression compared to the median of the sample set. The results were collated with data obtained from the RNA-seq analysis.

Involvement of DPP9 in gene fusions in serous ovarian carcinoma.
