Heart RNA-seq of control mice and mice with titin PEVK domain knockout, Rbm20 RNA recognition motif knockout, or double knockout

ABSTRACT: We report the heart RNA-sequencing of control animals (129S6 genetic background, wild type). Animal models comprise of Titin PEVK homozygous deletion of exons 219-225 (PEVK-KO), RBM20 heterozygous deletion of exons 6-7 (RBM20-HET), and double deletion (PEVK-KOxRBM20-HET). RNA from left ventricular tissue was isolated using TRIzol followed by a clean-up with the QIAGEN RNA micro kit, cDNA libraries were generated using the Illumina TruSeq Stranded mRNA Sample Prep Kit 2x101 paired-end sequenced on HiSeq2000 (WT, RBM20-HET) or HiSeq4000 (PEVK-KOxRBM20-HET). Trimming and quality clipping was performed with Flexbar v. 3.03. The remaining reads greater than 18bp were mapped to the murine genome (assembly EnsEMBL 84) with the splice-aware STAR aligner v. 2.5.1b. Transcriptome analyses on differential gene and isoform abundance were carried out with cuffdiff 20 v. 2.2.1.

Lung-resident myeloid-derived suppressor cells display dual functionality in experimental tuberculosis

Project description:Using cell-based approaches and experimental mouse models for pulmonary TB we unveiled MDSCs as new myeloid populations directly interacting with Mycobacterium tuberculosis (Mtb). MDSCs readily phagocytosed Mtb, released proinflammatory (IL-6, IL-1M-NM-1) and immunomodulatory (IL-10) cytokines while retaining their suppressive capacity. MDSCs were identified at the site of infection in disease-resistant and -susceptible mice during pulmonary TB. Excessive MDSC accumulation in lungs correlated with elevated surface expression of IL-4RM-NM-1 and heightened TB lethality. Microarray experiments were performed as dual-color hybridizations on Agilent mouse whole genome catalog 44K arrays. To compensate for dye-specific effects, a dye-reversal color-swap was applied.

Telomeric retrotransposon HeT-A contains a bidirectional promoter that initiates divergent transcription of piRNA precursors in Drosophila germline

Project description:PIWI-interacting (pi) RNAs provide silencing of transposable elements (TE) in the germline. Drosophila telomeres are maintained by transpositions of specialized telomeric retroelements. piRNAs generated from sense and antisense transcripts of telomeric elements provide telomere length control in the germline. Previously, we have found that antisense transcription of the major telomeric retroelement HeT-A is initiated upstream of the HeT-A sense transcription start site. Here, we performed a deletion analysis of the HeT-A promoter and show that common regulatory elements are shared by sense and antisense promoters of HeT-A. Therefore, the HeT-A promoter is a bidirectional promoter capable of processive sense and antisense transcription. Ovarian small RNA data shows that a solo HeT-A promoter within an euchromatic transgene initiates divergent transcription of transgenic reporter genes and subsequent processing of these transcripts into piRNAs. These events lead to the formation of a divergent uni-strand piRNA cluster at solo HeT-A promoters, in contrast to endogenous telomeres that represent strong dual-strand piRNA clusters. Solo HeT-A promoters are not immunoprecipitated with Heterochromatin Protein 1 (HP1) homolog Rhino, a marker of the dual-strand piRNA clusters, but are associated with HP1 itself, which provides piRNA-mediated transcriptional repression of the reporter genes. Unlike endogenous dual-strand piRNA clusters, the solo HeT-A promoter does not produce overlapping transcripts. In a telomeric context, however, bidirectional promoters of tandem HeT-A repeats provide read-through transcription of both genomic strands, followed by Rhi binding. These data indicate that Drosophila telomeres share properties of uni-strand and dual-strand piRNA clusters.

Reduced Slc1a1 expression is associated with neuroinflammation and impaired sensorimotor gating and cognitive performance in mice: implications for schizophrenia

Project description:We characterized the in vivo and in vitro consequences of reduced expression of Slc1a1 in mice. Heterozygous (HET) Slc1a1+/- mice, which model the hemi-deletion we found in human subjects with schizophrenia, were examined in a series of behavioral, anatomical and biochemical assays. Knockout (KO) mice were also included in the behavioral studies for comparative purposes. Both HET and KO mice exhibited evidence of increased anxiety-like behavior, impaired working memory, decreased exploratory activity and impaired sensorimotor gating, but no changes in overall locomotor activity compared to wildtype (WT) mice. The magnitude of changes was approximately equivalent in the HET and KO mice suggesting a dominant effect of the haploinsufficiency. Whole transcriptome RNA-Seq analysis detected expression changes of genes and pathways involved in cytokine signaling and synaptic functions in both brain and blood of the HET mice compared to WT mice.

Molecular and transcriptional characterization of chromosome 17p loss in chronic lymphocytic leukemia

Project description:Distinct genetic abnormalities such as TP53 deletion at 17p13.1, have been identified as having an adverse prognostic relevance in B-cell chronic lymphocytic leukemia (B-CLL). Conventional cytogenetic studies have shown that TP53 deletion in B-CLL is associated predominantly with 17p loss resulting from complex chromosomal rearrangements. We performed genome-wide DNA (SNPs arrays), fluorescence in situ hybridization (FISH) and gene expression profiling (GEP) analyses to investigate the significance of 17p loss in a panel of 71 genetically well-characterized B-CLLs in Binet stage A, 18 of which carried a TP53 monoallelic deletion. Combined SNP arrays and FISH approaches showed 17p loss in all of the TP53-deleted cases, with breakpoints scattered along the 17p11.2 region. Mutations in exons 5 to 9 of TP53 were found in 9/12 deleted samples. GEP of 60 B-CLLs, including 7 patients with 17p loss, identified 40 differentially expressed genes in 17p- versus 17p normal samples, 35 of which were down-regulated in 17p- tumors. The majority (30/35) of these transcripts, including putative tumor suppressor genes, mapped to 17p. Overall, these data indicate that, beside TP53 deletion, the concomitant loss of 17p arm may contribute to the strong negative prognostic impact known to be associated with this lesion in B-CLL. This SuperSeries is composed of the following subset Series: GSE9992: Molecular and transcriptional characterization of chromosome 17p loss in chronic lymphocytic leukemia, experiment A GSE11036: Molecular and transcriptional characterization of chromosome 17p loss in chronic lymphocytic leukemia, experiment B Keywords: SuperSeries Refer to individual Series
