Description
Recent studies have shown that the RNA binding protein Musashi 2 (Msi2) plays prominent roles during development and leukemia. Additionally, in embryonic stem cells (ESC) undergoing the early stages of differentiation, Msi2 has been shown to associate with Sox2, which is required for the self-renewal of ESC. These findings led us to examine the effects of Msi2 on the behavior of ESC. Using an shRNA sequence that targets Msi2 and a scrambled shRNA sequence, we determined that knockdown of Msi2 disrupts the self-renewal of ESC and promotes their differentiation. Collectively, our findings argue that Msi2 is required to support the self-renewal and pluripotency of ESC.

Description
Coordinate expression of the somatic cell reprogramming factors Oct4, Sox2, Klf4 and c-Myc within embryonic stem cells preserves the self-renewal of these cells, while allowing for the expression epitope tagged Sox2. Taking advantage of this observation, we engineered embryonic stem cells (i-OSKM-ESC) to inducibly express Oct4, Klf4, c-Myc and an epitope tagged form of Sox2 from a polycistronic element, in the presence of doxycycline. We isolated Sox2 and its associated protein complexes by co-immunoprecipitation. Subsequently, we identified the Sox2-protein interactome in self-renewing embryonic stem cells using an unbiased proteomic screen (Multidimensional Protein Identification Technology [MudPIT]).

Description
While long noncoding RNAs (lncRNAs) and mRNAs share similar biogenesis pathways, these two transcript classes differ in many regards. LncRNAs are less conserved, less abundant, and more tissue specific than mRNAs, implying that our understanding of lncRNA transcriptional regulation is incomplete. Here, we perform an in depth characterization of numerous factors contributing to this regulation. We find that lncRNA promoters contain fewer transcription factor binding sites than do those of mRNAs, with some notable exceptions. Surprisingly, we find that H3K9me3 –typically associated with transcriptional repression–is enriched at active lncRNA loci. However, the most discriminant differences between lncRNAs and mRNAs involve splicing: only half of lncRNAs are efficiently spliced, which can be partially attributed to defects in lncRNA splicing signals and diminished U2AF65 binding. These attributes are conserved between humans and mice. Finally, we find that certain transcriptional properties are enriched in known, functionally characterized lncRNAs, demonstrating that our multidimensional analysis might discern lncRNAs that are likely to be functional Overall design: Examination of RNA abundance in two cell lines (K562 and Hues9) and 5 time points after actinomycin D treatment. Three replicates per time point and cell type.

Description
We carried out a global survey of age-related changes in mRNA levels in the C57BL/6NIA mouse hippocampus and found a difference in the hippocampal gene expression profile between 2-month-old young mice and 15-month-old middle-aged mice correlated with an age-related cognitive deficit in hippocampal-based explicit memory formation. Middle-aged mice displayed a mild but specific deficit in spatial memory in the Morris water maze.

Description
RNA transcriptome difference between WT and SFR KO iNKT cells To understand how SLAM family receptors (SFRs) contribute to iNKT cell development, a mouse lacking all SFRs in addition to the ligand of 2B4, CD48, was generated, and the transcriptional profiles of thymic iNKT cells from wild-type and SFR KO mice were compared, using RNA sequencing. Overall design: Examine RNA expression in WT and SFR KO iNKT cells Thymocytes were isolated from WT and SFR KO mice, and iNKT cells were enriched by negative selection. Unwanted cells (CD11b+ CD11c+ Gr-1+ Ter-119+ CD19+ CD8a+ cells) were targeted for removal with biotinylated antibodies (BioLegend), streptavidin-coated magnetic particles (RapidSpheres) and EasySep magnet (STEMCELL), and followed by staining with mCD1d/PBS-57 and anti-TCR. Then, iNKT cells were sorted with BD FACSAria III (BD Biosciences), and total RNA was isolated from sorted cells according to the manufacturer's instructions using the RNeasy plus micro kit (Qiagen). RNA-Seq library preparation was performed using the Illumina TruSeq Stranded mRNA Kit, according to manufacturer's instructions, and sequenced with Illumina HiSeq 2000 Sequencer. Read quality was confirmed using FastQC v0.10.1 before alignment using TopHat v2.0.10 on the mouse GRCm38/mm10 genome.
