Long Non-Coding RNA MEG3 Promotes Angiogenesis by directly regulating integrin signaling impairing endothelial cell function [ChIP-seq]

ABSTRACT: We immunoprecipitated EZH2, together with associated chromatin isolated from the HUVECs (2 x 10^6) that were transfected with MEG3 GapmeRs (10 nM, 48 h) or a scrambled control GapmeRs (Ctr). For transfection, we used 10 nM scrambled LNA (locked nucleic acids) GapmeR control (Cat. No. 339515) or phosphorothioate antisense standard GapmeRs MEG3-lncRNA (Cat No. 339511, Qiagen). On beads crosslinked chromatin complexes were reversed, and DNA purified using QIAquick® PCR Purification Kit and quantified by Qubit HS assay (Q33230)

ChIP-seq in MEG3+ and MEG3- hIPSCs

Project description:In this experiment we sought to identify region with differential PRC2, JARID2, and H3K27me3 occupancy in human induced pluripotent stem cell lines with silenced or expressed MEG3 locus to indirectly determine the effect of this ncRNA on PRC2 function. 8 hIPSC lines, 5 MEG3+ and 3 MEG3-; ChIP-seq for EZH2, JARID2, and H3K27me3. Some done in replicates.

Gene expression analysis in liver collected from mice administered non-toxic, toxic, or severely toxic LNA sequences

Project description:Development of LNA gapmers, antisense oligonucleotides used for efficient inhibition of target RNA expression, is limited by non-target mediated hepatotoxicity issues. In the present study, we investigated hepatic transcription profiles of mice receiving non-toxic and toxic LNA gapmers after a single and repeat administration. To understand the mechanism of LNA gapmer-induced heptotoxicity in mice, we investigated the transcription profiles of liver RNA isolated from mice receiving non-toxic sequence (NTS-1), toxic sequence (TS-2), or severely toxic sequence (HTS-3) of LNA gapmers at 25 mg/kg (dose volume of 10 mL/kg) at 8, 16, or 72 hrs after a single administration (by subcutaneous injection ) using microarray analysis. We also investigated the transcription profiles of liver RNA isolated from mice receiving non-toxic sequence (NTS-1) or toxic sequence (TS-2) of LNA gapmers at 25 mg/kg (dose volume of 10 mL/kg) at 2 weeks after repeated administration (by subcutaneous injection ) using microarray analysis.

overexpression/knockdown MEG3 in C2C12 cell lines

Project description:MEG3 was known as a growth suppressor in tumor cells by activating p53. Besides, MEG3 could regulate transforming growth factor-β (TGF-β) signaling pathway, which is the key regulator of skeletal myogenesis and can enhance the proliferation of myogenic cells. Previous study also showed MEG3 was highly expressed in the paraxial mesoderm and probably regulated muscle development. To investigate the potential function of MEG3 in muscle development, we detected the expression levels of protein-coding genes after MEG3 over-expression or knockdown in C2C12 cell line using microarrays.

Meg3 regulated genes in pancreatic beta cells

Project description:Meg3 is a long non-coding RNA. It's target genes are unknown. The mouse pancreatic beta cell line MIN6-4N was used to assess the expression of genes upon stable Meg3 overexpression Stable cell lines were isolated that have integated pcDNA3.1 or pcDNA3.1-mMeg3.The cells were processed for RNA isolation. The level of Meg3 expression was assessed by RT-PCR. RNA preps were used for microarray analysis.

ChIP-seq in MRC5 hIPSCs overexpressing MEG3 RNA.

Project description:This experiment was designed to detect differences in PRC2 occupancy in a human induced pluripotent cell line (MRC5) naturally deficient in MEG3 RNA after lentiviral overexpression of MEG3. MRC5 were transduced with lentiviruses for the overexpression of MEG3 lncRNA or GFP as a control. ChIP-seq was performed with EZH2 and JARID2 antibodies.

The transcription factor SOX6 contributes to the developmental origins of obesity by promoting adipogenesis through inhibition of Wnt signaling

Project description:The developmental transcription factor SOX6 was found to regulate serum, as well as liver triglycerides in BL6 mice treated with SOX6 antisense gapmers compared to control gapmers. SOX6 was initially discovered as a gene over-expressed in mesenchymal stem cells derived from small for gestational age newborns. We characterized its metabolic function in BL6 mice using the above antisense knockdown approach. BL6 mice were treated with either SOX6 specific or control gapmer oligonucleotides for 48h. Knockdown efficiency was measured in liver and epididymal white adipose tissues and serum levels of triglycerides and cholesterol quantified.

Meg3 binding sites in mouse insulinoma cells

Project description:We have shown that increased β-cell proliferation in functioning pancreatic neuroendocrine tumors (insulinomas) correlated with reduced expression of the long non-coding RNA Meg3 and increased expression of the oncogenic receptor c-Met. To investigate the target binding sites of Meg3 in and around the c-Met gene, we did ChIRP-Seq using biotinylated probes from the mouse Meg3 RNA sequence. This would help us better understand how Meg3 regulates ithe expression of c-Met to control β-cell proliferation in insulinoma cells.
