Andersson R, Gebhard C, Miguel-Escalada I, et al., 2014, An atlas of active enhancers across human cell types and tissues., Nature, Vol: 507, Pages: 455-461
Enhancers control the correct temporal and cell-type-specific activation of gene expression in multicellular eukaryotes. Knowing their properties, regulatory activity and targets is crucial to understand the regulation of differentiation and homeostasis. Here we use the FANTOM5 panel of samples, covering the majority of human tissues and cell types, to produce an atlas of active, in vivo-transcribed enhancers. We show that enhancers share properties with CpG-poor messenger RNA promoters but produce bidirectional, exosome-sensitive, relatively short unspliced RNAs, the generation of which is strongly related to enhancer activity. The atlas is used to compare regulatory programs between different cells at unprecedented depth, to identify disease-associated regulatory single nucleotide polymorphisms, and to classify cell-type-specific and ubiquitous enhancers. We further explore the utility of enhancer redundancy, which explains gene expression strength rather than expression patterns. The online FANTOM5 enhancer atlas represents a unique resource for studies on cell-type-specific enhancers and gene regulation.

Pascarella G, Lazarevic D, Plessy C, et al., 2014, NanoCAGE analysis of the mouse olfactory epithelium identifies the expression of vomeronasal receptors and of proximal LINE elements., Front Cell Neurosci, Vol: 8
By coupling laser capture microdissection to nanoCAGE technology and next-generation sequencing we have identified the genome-wide collection of active promoters in the mouse Main Olfactory Epithelium (MOE). Transcription start sites (TSSs) for the large majority of Olfactory Receptors (ORs) have been previously mapped increasing our understanding of their promoter architecture. Here we show that in our nanoCAGE libraries of the mouse MOE we detect a large number of tags mapped in loci hosting Type-1 and Type-2 Vomeronasal Receptors genes (V1Rs and V2Rs). These loci also show a massive expression of Long Interspersed Nuclear Elements (LINEs). We have validated the expression of selected receptors detected by nanoCAGE with in situ hybridization, RT-PCR and qRT-PCR. This work extends the repertory of receptors capable of sensing chemical signals in the MOE, suggesting intriguing interplays between MOE and VNO for pheromone processing and positioning transcribed LINEs as candidate regulatory RNAs for VRs expression.

Zuin J, Franke V, van Ijcken WF, et al., 2014, A cohesin-independent role for NIPBL at promoters provides insights in CdLS., PLoS Genet, Vol: 10
The cohesin complex is crucial for chromosome segregation during mitosis and has recently also been implicated in transcriptional regulation and chromatin architecture. The NIPBL protein is required for the loading of cohesin onto chromatin, but how and where cohesin is loaded in vertebrate cells is unclear. Heterozygous mutations of NIPBL were found in 50% of the cases of Cornelia de Lange Syndrome (CdLS), a human developmental syndrome with a complex phenotype. However, no defects in the mitotic function of cohesin have been observed so far and the links between NIPBL mutations and the observed developmental defects are unclear. We show that NIPBL binds to chromatin in somatic cells with a different timing than cohesin. Further, we observe that high-affinity NIPBL binding sites localize to different regions than cohesin and almost exclusively to the promoters of active genes. NIPBL or cohesin knockdown reduce transcription of these genes differently, suggesting a cohesin-independent role of NIPBL for transcription. Motif analysis and comparison to published data show that NIPBL co-localizes with a specific set of other transcription factors. In cells derived from CdLS patients NIPBL binding levels are reduced and several of the NIPBL-bound genes have previously been observed to be mis-expressed in CdLS. In summary, our observations indicate that NIPBL mutations might cause developmental defects in different ways. First, defects of NIPBL might lead to cohesin-loading defects and thereby alter gene expression and second, NIPBL deficiency might affect genes directly via its role at the respective promoters.
Armant O, März M, Schmidt R, et al., 2013, Genome-wide, whole mount in situ analysis of transcriptional regulators in zebrafish embryos., Dev Biol, Vol: 380, Pages: 351-362
Transcription is the primary step in the retrieval of genetic information. A substantial proportion of the protein repertoire of each organism consists of transcriptional regulators (TRs). It is believed that the differential expression and combinatorial action of these TRs is essential for vertebrate development and body homeostasis. We mined the zebrafish genome exhaustively for genes encoding TRs and determined their expression in the zebrafish embryo by sequencing to saturation and in situ hybridisation. At the evolutionary conserved phylotypic stage, 75% of the 3302 TR genes encoded in the genome are already expressed. The number of expressed TR genes increases only marginally in subsequent stages and is maintained during adulthood suggesting important roles of the TR genes in body homeostasis. Fewer than half of the TR genes (45%, n=1711 genes) are expressed in a tissue-restricted manner in the embryo. Transcripts of 207 genes were detected in a single tissue in the 24h embryo, potentially acting as regulators of specific processes. Other TR genes were expressed in multiple tissues. However, with the exception of certain territories in the nervous system, we did not find significant synexpression suggesting that most tissue-restricted TRs act in a freely combinatorial fashion. Our data indicate that elaboration of body pattern and function from the phylotypic stage onward relies mostly on redeployment of TRs and post-transcriptional processes.
Carvalho RH, Hou J, Haberle V, et al., 2013, Genomewide DNA methylation analysis identifies novel methylated genes in non-small-cell lung carcinomas., J Thorac Oncol, Vol: 8, Pages: 562-573
INTRODUCTION: DNA methylation is part of the epigenetic regulatory mechanism present in all normal cells. It is tissue-specific and stably maintained throughout development, but often abnormally changed in cancer. Non-small-cell lung carcinoma (NSCLC) is the most deadly type of cancer, involving different tumor subtypes. This heterogeneity is a challenge for correct diagnosis and patient treatment. The stability and specificity make of DNA methylation a very suitable marker for epigenetic phenotyping of tumors. METHODS: To identify candidate markers for use in NSCLC diagnosis, we used genomewide DNA methylation maps that we had previously generated by MethylCap and next-generation sequencing and listed the most significant differentially methylated regions (DMRs). The 25 DMRs with highest significance in their methylation scores were selected. The methylation status of these DMRs was investigated in 61 tumors and matching control lung tissues by methylation-specific polymerase chain reaction. RESULTS: We found 12 novel DMRs that showed significant differences between tumor and control lung tissues. We also identified three novel DMRs for each of the two most common NSCLC subtypes, adenocarcinomas and squamous cell carcinomas. We propose a panel of five DMRs, composed of novel and known markers that exhibit high specificity and sensitivity to distinguish tumors from control lung tissues. CONCLUSION: Novel markers will aid the development of a highly specific epigenetic panel for accurate identification and subtyping of NSCLC tumors.
