Efficient cellular fractionation of RNA

ABSTRACT: The aim of this experiment was to develop new methods to extract pure fractions of nuclear and cytoplasmic RNA. We compared the results of nuclear and cytoplasmic RNA-sequencing to results of the total and polyA+ RNA-sequencing. Cytoplasmic, nuclear, total and polyA+ RNA was extracted from two human brain samples and sequenced on the SOLiD system. We analyzed the data to look for differences in levels of nascent transcription and mature mRNAs between the different samples.

<h4>Background</h4>The starting material for RNA sequencing (RNA-seq) studies is usually total RNA or polyA+ RNA. Both forms of RNA represent heterogeneous pools of RNA molecules at different levels of maturation and processing. Such heterogeneity, in addition to the biases associated with polyA+ purification steps, may influence the analysis, sensitivity and the interpretation of RNA-seq data. We hypothesize that subcellular fractions of RNA may provide a more accurate picture of gene expressio ...[more]

The polyA+ transcriptomes of mouse embryonic stem cells and their derived neural precursors from strand-specific RNA-Seq

Project description:We have examined the nuclear (nuc) and cytoplasmic (cyt) polyA+ transcriptomes of undifferentiated mouse embryonic stem cells (un) and cells differentiated to neural precursors (d5) using strand-specific RNA-Seq. The 46C mouse embryonic stem cell line was used for this study. Two cell types were examined: undifferentiated mouse embryonic stem cells (un) and cells differentiated to neural precursors (d5). For each cell type, cells were fractionated to nuclear and cytoplasmic components. RNAs were extracted from each component and were fragmented enzymatically for library construction. For each cell type and component, strand-specific RNA-Seq libraries were generated using at least two different fragmentation protocols.

Microprocessor mediates transcription termination in long noncoding microRNA genes

Project description:MicroRNA (miRNA) play a major role in the post-transcriptional regulation of gene expression. In mammals most miRNA derive from the introns of protein coding genes where they exist as hairpin structures in the primary gene transcript, synthesized by RNA polymerase II (Pol II). These are cleaved co-transcriptionally by the Microprocessor complex, comprising DGCR8 and the RNase III endonuclease Drosha, to release the precursor (pre-)miRNA hairpin, so generating both miRNA and spliced messenger RNA1-4. However, a substantial minority of miRNA originate from Pol II-synthesized long non coding (lnc) RNA where transcript processing is largely uncharacterized5. Here, we show that most lnc-pri-miRNA do not use the canonical cleavage and polyadenylation (CPA) transcription termination pathway6, but instead use Microprocessor cleavage both to release pre-miRNA and terminate transcription. We present a detailed characterization of one such lnc-pri-miRNA that generates the highly expressed liver-specific miR-1227. Genome-wide analysis then reveals that Microprocessor-mediated transcription termination is commonly used by lnc-pri-miRNA but not by protein coding miRNA genes. This identifies a fundamental difference between lncRNA and pre-mRNA processing. Remarkably, inactivation of the Microprocessor can lead to extensive transcriptional readthrough of lnc-pri-miRNA, resulting in inhibition of downstream genes by transcriptional interference. Consequently we define a novel RNase III-mediated, polyadenylation-independent mechanism of Pol II transcription termination in mammalian cells. Chromatin associated RNA-seq from sicntrl,siDrosha,siDGCR8 treated Hela cells. Same for sicntrl and siDGCR8 from Huh7 cells. Nuclear polyA + and polyA- RNA-seq from sicntrl and siDGCR8 in HeLa cells.

Nuclear-localized tiny RNAs are associated with transcription initiation and splice sites in metazoans

Project description:We have recently shown that transcription initiation RNAs (tiRNAs) are derived from sequences downstream of transcription start sites. Here we report the identification of a second class of nuclear-specific ~17-18 nucleotide small RNA whose 3M-bM-^@M-^Y ends map precisely to the splice donor site of internal exons in animals. These splice-site RNAs (spliRNAs) are associated with highly expressed genes, and show evidence of developmental stage- and region-specific expression. We also confirm that tiRNAs are nuclear localized, enriched at chromatin marks associated with transcription initiation, and possess a 3M-bM-^@M-^Y nucleotide bias. Additionally, we find that microRNA-offset RNAs (moRNAs), the oncogenic miR-15/16 cluster and most snoRNA-derived small RNAs (sdRNAs) are enriched in the nucleus, whereas most miRNAs and two H/ACA sdRNAs are cytoplasmically enriched. We propose that nuclear localized tiny RNAs are involved in epigenetic regulation of gene expression. Discovery and characterization of small RNA species through high-througput deep sequencing of nuclear, cytoplasmic and total small RNA fractions from THP-1 cells, a monocytic leukemia cell line.

Extensive crosstalk between lncRNAs and mRNAs in mouse stem cells

Project description:To determine the temporal variation of mRNA levels, we collected and sequenced poly-adenylated RNA from all cell extracts, cytoplasmic and nuclear fractions of a conditional Dicer mutant [DTCM23/49 XY (Nesterova et al. 2008)] mouse Embryonic Stem Cells before induction of Dicer excision (day 0) and at days 4, 8, 10 and 12 following Dicer loss of function. coverage. RNA from whole cell extracts was collected at days 0, 4, 8, 10 and 12 following loss of Dicer function and from the cytoplasmic and nuclear fractions of cell at day 0 and 12. Three biological replicates were obtained for all samples. Poly-adenylated directional 100 base paired-end sequencing libraries were prepared for all extracts and sequenced by BGI solutions (Hong Kong).

Global microRNA profiling of mouse hemopoietic stem cells (LSKs), promyelocytes, myelocytes and granulocytes.

Project description:This study sought to determine the dynamic changes of miRNA expression during mouse granulopoiesis. We not only performed analyses of miRNA expression levels in whole cells but also analyzed purified nuclear and cytoplasmic cell fractions to profile miRNA subcellular localization. qRT-PCR analysis of miRNAs was performed on whole cell, nuclear and cytoplasmic RNAs extracted from mouse hemopoietic stem cells (LSKs), promyelocytes, myelocytes and granulocytes. 100 ng of RNA was reversed transcribed using the Taqman miRNA Reverse Transcription Kit and Megaplex RT Primers rodent pool A and B (Life Technologies). Complementary DNA (cDNA) was amplified using a TaqMan rodent microRNA A and B Array v2.0 (Life Technologies) with TaqMan Universal PCR Master Mix on an ABI 7900HT Sequence Detection System.
