Long Non-coding RNAs Control Hematopoietic Stem Cell (HSC) Function (ChIRP-seq)

ABSTRACT: Long non-coding RNAs (lncRNAs) have recently emerged as new players in gene expression regulation. Whether and how lncRNAs might control hematopoietic stem cell (HSC) function remains largely unknown. Here, we profiled the transcriptome of purified long-term HSCs by deep RNA-sequencing and identified thousands of un-annotated transcripts of which 323 are predicted to be lncRNAs. Comparison of their expression in differentiated lineages represented by B cells (B220+) and Granulocytes (Gr1+), revealed that 159 are likely to be HSC-specific. Knockdown of two such non-coding genes (LincHSC-1 and LincHSC-2) indicated that they regulate HSC lineage differentiation, possibly via targeting cell cycle regulators and chromatin modification enzymes. Taken together, we comprehensively identify lncRNAs in HSC and show to examples that play important roles in HSC function.

cis regulated role of lncRNA in transcriptional or developmental process (ChIRP-Seq)

Project description:We report that long noncoding RNAs contribute to transcription and developmental process. Thousands of lncRNAs have been identified in the whole genome, and tend to located closely to protein-coding genes. To study position relationship between lncRNA and protein-coding genes, we classified all of lncRNA to several subgroups based on the genome position with their coding neighbors. XH, the head to head subgroup is associated with transcription and development in GO analysis. Here, we knockdown serveral XH lncRNA by shRNA in embryonic stem cells and induce nondirectional differnetiation by removing LIF or neural differnetiation by RA. Knockdown of XH lncRNAs led to uniform downregulation of nearby coding genes, and form regulatory circuits with its nearby coding genes to fine-tune embryonic lineage development. In addition, we also knockout one lncRNA-Evx1as and its nearby protein-coding gene-EVX1 by CRISPR, and get similar results as knockdown.We propose that XH lncRNA may function primarily as 'cis-regulators' of the expression of nearby protein-coding genes, and tend to participate in transcriptional or development regulations as their coding neighbors. All RNA-seq(s) were designed to reveal the differentially expressed genes between wild-type and XH lncRNA knockdown/knockout ESCs during differentiation.

ChIRP-MS of the lncRNA SAMMSON in uveal melanoma

Project description:Long non-coding RNAs (lncRNAs) can exhibit cell-type or even cancer-type specific expression profiles, making them highly attractive as therapeutic targets. PAN cancer RNA sequencing data revealed sustained expression of the SAMMSON lncRNA in uveal melanoma (UM), the most common primary intraocular malignancy in adults. Currently, there are no effective treatments for UM patients with metastatic disease, resulting in a median survival time of 6-12 months. We aimed to investigate the therapeutic potential of SAMMSON inhibition in UM.

ChIRP-MS dataset generated from Prohibitin 2 orchestrating transcription of long noncoding RNA and coding gene to accelerate tumorigenesis

Project description:The spatial co-presence of aberrant long non-coding RNAs (lncRNAs) and abnormal coding genes contributes to malignancy development in various tumors. However, precise coordinated mechanisms underlying this phenomenon in tumorigenesis remains incompletely understood. Here, we show that Prohibitin 2 (PHB2) orchestrates the transcription of an oncogenic CASC15-New-Isoform 2 (CANT2) lncRNA and the coding tumor-suppressor gene CCBE1, thereby accelerating melanoma tumorigenesis. In melanoma cells, to further capture the binding proteins of CANT2, ChIRP-MS was performed.

LncRNA CHROMR regulates antiviral immunity in humans [ChIRP-Seq]

Project description:Long non-coding RNAs (lncRNAs) are important regulators of the immune response. Here we identify a novel function for the primate-specific lncRNA, CHROMR. We established that CHROME is most highly transcribed in human macrophages treated with influenza virus and/or polyIC.

Growth factor independence 1 (Gfi1) regulates cell-fate decision of the bipotential granulocytic-monocytic precursor defined by the expression of CD48 as a new marker

Project description:Using bone marrow cells of GFP:Gfi1 knock in mice, we separated Gfi1-high and Gfi1-low expressing cells in the classical CD11b+, GR1-low monocytic cell fraction. We sorted CD11b+, GR1-low GFP:Gfi1-high and low cells as well as CD11b+, GR1-high granulocytes and CD11b-high, GR1-intermediate cells from Gfi1-knock-out mice for further analysis. We used Affymetrix Mouse Genome 430A 2.0 arrays (GPL8321) The study should determine how Gfi1 regulates the cell fate of monocytes/granulocytes in mice

Transcription profiling of mouse Gr1- and Gr1+ monocytes

Project description:Six-weeks old (C57Bl6, Cx3cr1gfp/+) mice were intraperitonealy infected with a low number (1.104) of L. monocytogenes (EGDe strain) in exponential growth phase (bacteria were grown in BHI at 108/ml, and diluted 10.000x in PBS immediately before injection). Group of three mice were euthanized, before infection. Peritoneal cells were recovered by peritoneal lavage. Cells from individual mice were stained with antibodies to CD11b (PECy7), Gr1 (APC), NK1.1, B220 and CD3 (PE), and F4/80 (biotin-conjugated followed by streptavidinpacific blue) for sorting. Gr1- monocytes were purified as NK1.1- CD3- B220- CD11b+ F4/80low Gr1-, gfphigh; Gr1+ monocytes were purified as NK1.1- CD3- B220- CD11b+ F4/80low Gr1+, gfpint; and polymorphonuclear cells were purified as NK1.1- CD3- B220- CD11b+ F4/80- Gr1high, gfp-. 1.103 cells from each mice, time point, and phenotype were purified by facs sorting according to their phenotype. Samples were kept at 4°C before and during the sort. Cells were directly sorted in the SuperAmp Lysis Buffer (Miltenyi Biotec, Bergisch Gladbach, Germany) using a FACS Aria cell-sorter (BD biosciences).

ChIRP-MS of long non-coding RNA HOTAIR

Project description:Accumulating evidence highlights the role of long non-coding RNAs (lncRNA) in cellular homeostasis, and their dysregulation in disease settings. Most lncRNAs function by interacting with proteins or protein complexes. While several orthogonal methods have been developed to identify these proteins, each method has its inherent strengths and limitations. Here, we combine two RNA-centric methods ChIRP-MS and RNA-BioID to obtain a comprehensive list of proteins that interact with the well-known lncRNA HOTAIR. Overexpression of HOTAIR has been associated with a metastasis-promoting phenotype in various cancers. Although HOTAIR is known to bind with PRC2 and LSD1 protein complexes, an unbiased and comprehensive method to map its interactome has not yet been performed. Both ChIRP-MS and RNA-BioID data sets show an association of HOTAIR with mitoribosomes, suggesting HOTAIR has functions independent of its (post-)transcriptional mode-of-action.
