Description
Noncoding RNAs (ncRNAs) comprise an important class of natural regulators that mediate a vast array of biological processes, including the modulation of chromatin architecture. Moreover, artificial ncRNAs have revealed that the functional capabilities of RNA are extremely broad. To further investigate and harness these capabilities, we developed CRISPR-Display ("CRISP-Disp"), a targeted localization strategy that uses Cas9 to deploy large RNA cargos to specific DNA loci. We demonstrate that exogenous RNA domains can be functionally appended onto the CRISPR scaffold at multiple insertion points, allowing the construction of Cas9 complexes with RNAs nearing one kilobase in length, with structured RNAs, protein-binding cassettes, artificial aptamers and pools of random sequences. CRISP-Disp also allows the simultaneous multiplexing of disparate functions at multiple targets. We anticipate that this technology will provide a powerful method with which to ectopically localize functional RNAs and ribonuceloprotein complexes at specified genomic loci. Overall design: Whole cell poly(A) selected RNA seq, from HEK293FT cells bearing lentivirally-integrated Gaussia and Cypridina luciferase reporter loci. Cells were transiently transfected with dCas9~VP64 alone, or with dCas9~VP and one of several modified sgRNAs,each targeting the Gaussia reporter.

Description
Adipogenesis involves the regulation of hundreds of genes by several well-studied proteins, but the role of long, noncoding RNAs in this process has not been defined. We track the regulation of hundreds of lncRNAs during adipocyte differentiation, and find several that are essential for this process.

Description
Adipogenesis involves the regulation of hundreds of genes by several well-studied proteins, but the role of long, noncoding RNAs in this process has not been defined. We track the regulation of hundreds of lncRNAs during adipocyte differentiation, and find several that are essential for this process. Overall design: We extractedbrown and white primary adipocytes and pre-adipocytes and profiled lncRNA expresssion via mRNA-Seq. We also profiled cultured, differentiated adipocytes to verify that we could recapitulate the adipocyte expression profile in preparation for a loss-of-function screen for essential adipogenic lincRNAs.

Description
High resolution transcriptional profiling of H1-derived human neuronal precursor cells over a timecourse of differentiation in vitro. Overall design: Human NPC differentiation timecourse covers Days 0,1,2,4,5,11, and 18 after induction of neuronal differentiation as described in manuscript. Each time point was assayed in triplicate cultures with the exception of Day 5, in which one outlier culture has been removed.

Description
We investigated Smad4-mediated TGF-beta signaling in the development of occipital somite-derived myogenic progenitors during tongue morphogenesis by comparing the transcriptomes of tongue derived from Myf5-Cre;Smad4flox/flox mutant and Myf5-Cre;Smad4flox/+ control mice at day E13.5. Based on gene expression profiles and functional studies, we elucidated the influences Smad4 activity and TGF-beta signaling have on the gene expression profiles underlying tongue development. The data are consistent with the hypothesis that TGF-beta-Smad4-FGF6 signaling cascade plays a crucial role in myogenic cell fate determination and lineage progression during tongue myogenesis.

Description
The objective of this study was to elucidate age-related differences in gene expression profiles of rhesus monkey bone marrow-derived mesenchymal stem cells (rhMSC) obtained from fetal, infant, and adult donors relevant to their growth and other properties. Although a high degree of similarity was observed in the rhMSC gene expression profiles when comparing the three age groups, significant differences were found that strongly parallel gene expression profiles of human MSC. The potential functional relevance of differential gene expression was most apparent when comparing fetal and adult rhMSC transcript profiles. Overall, the observed gene expression profiles are consistent with a loss of rhMSC pluripotency and proliferative capacity with advancing donor age. In addition, these data highlight the importance of use of non-human primates as a model system for studying the properties of human stem cells.

Description
Although not an affected cell type, skin fibroblasts from individuals with CC-ALD, an early onset X-linked neurological disorder, show defects in very long chain fatty acid (VLCFA) metabolism that provide the basis for clinical diagnostic tests. Skin fibroblasts from CC-ALD patients can be reprogrammed into iPS cells with all the hallmark properties of pluripotency. The iPS cell phenotypes may reflect the tissue-specificity of the lipid metabolic defects found in CC-ALD patients.

Description
Interactions between the gene products encoded by the mitochondrial and nuclear genomes play critical roles in normal eukaryotic cellular function. Here, we characterized the metabolic and transcriptional properties of A549 lung cancer cells and their isogenic mitochondrial DNA (mtDNA)-depleted rho zero counterparts grown in cell culture and as tumor xenografts in immune-deficient mice. A manuscript summarizing our conclusions is under review.
