Project description:Aim:Transcriptional analysis of the MIN6 beta cell line following control or Paupar lncRNA KD to identify genes regulated by Paupar Methods:MIN6 cells subjected to either control or Paupar KD were transfected for 48 hours before extraction of total RNA using the Qiagen Mini kit. Libraries were prepared from total RNA (RIN>8) with the TruSeq RNA prep kit (Illumina) and sequenced using the HiSeq2000 (Illumina) instrument. More than 30 million reads were mapped to the mouse genome (UCSC/mm9) using Tophat (version 2.0.4) with 4 mismatches and 10 maximum multiple hits. Significantly differentially expressed genes were calculated using DEseq2. Results: We did not observe any signficant changes in genes important for beta cell function Conclusion: Paupar does not have a signficant regulatory function in beta cells

Project description:Although some long noncoding RNAs (lncRNAs) have been shown to regulate gene expression in cis, it remains unclear whether lncRNAs can directly regulate transcription in trans by interacting with chromatin genome-wide independently of their sites of synthesis. Here, we describe the genomically local and more distal functions of Paupar, a vertebrate-conserved and central nervous system-expressed lncRNA transcribed from a locus upstream of the gene encoding the Pax6 transcription factor. Knockdown of Paupar disrupts the normal cell cycle profile of neuroblastoma cells and induces neuronal differentiation. Paupar acts in a transcript-dependent manner both locally, to regulate Pax6, as well as distally by binding and regulating genes on multiple chromosomes, in part through physical association with Pax6 protein. Paupar binding sites are enriched near promoters and can function as transcriptional regulatory elements whose activity is modulated by Paupar transcript levels. Our findings demonstrate that a lncRNA can function in trans at transcriptional regulatory elements distinct from its site of synthesis to control large-scale transcriptional programmes. N2A cells transfected with a non-targeting control vector were compared to N2A cells transfected with a Pax6 knockdown construct. Three biological replicates of each condition were analysed on Affymetrix GeneChip Mouse Gene 1.0 ST Arrays.

Our findings demonstrate that a lncRNA can function in trans at transcriptional regulatory elements distinct from its site of synthesis to control large-scale transcriptional programmes. The genome-wide binding profile of Paupar was determined using Capture Hybridisation Analysis of RNA Targets (CHART)-Seq technique (Simon et al, Proc Natl Acad Sci U S A 108: 20497-20502, 2011) in N2A cells. Following the CHART-seq protocol, we used RNase H elution to recover genomic DNA associated with endogenous Paupar transcripts and genomic DNA associated with a control oligonucleotide (corresponding to the E.coli LacZ sequence). We identified Paupar binding sites in comparison both to DNA recovered using the control LacZ oligonucleotide and to an input DNA sample from N2A cells.
