LHFPL3-AS2 lncRNA regulates epithelial polarity and its reduced expression is linked with more severe Crohn Disease

Project description:LHFPL3-AS2 lncRNA regulates epithelial polarity and its reduced expression is linked with more severe Crohn Disease

Reduced LHFPL3-AS2 lncRNA expression is linked to altered epithelial polarity and proliferation, and to ileal ulceration in Crohn disease.

Project description:Disruption of intestinal epithelial functions is linked to Crohn disease (CD) pathogenesis. We identified a widespread reduction in the expression of long non-coding RNAs (lncRNAs) including LHFPL3-AS2 in the treatment-naïve CD ileum of the RISK pediatric cohort. We validated the reduction of LHFPL3-AS2 in adult CD and noted a further reduction in patients with more severe CD from the RISK cohort. LHFPL3-AS2 knockdown in Caco-2 cells robustly affected epithelial monolayer morphogenesis with markedly reduced confluency and spreading, showing atypical rounding, and clumping. mRNA-seq analysis of LHFPL3-AS2 knockdown cells highlighted the reduction of genes and pathways linked with apical polarity, actin bundles, morphogenesis, and the b-catenin-TCF4 complex. LHFPL3-AS2 knockdown significantly reduced the ability of cells to form an internal lumen within the 3-dimensional (3D) cyst model, with mislocalization of actin and adherent and tight junction proteins, affecting epithelial polarity. LHFPL3-AS2 knockdown also resulted in defective mitotic spindle formation and consequent reduction in epithelial proliferation. Altogether, we show that LHFPL3-AS2 reduction affects epithelial morphogenesis, polarity, mitotic spindle formation, and proliferation, which are key processes in maintaining epithelial homeostasis in CD. Reduced expression of LHFPL3-AS2 in CD patients and its further reduction with ileal ulceration outcome, emphasizes its significance in this context.

Analysis of genes regulated by AS1 and AS2

Project description:AS1 and AS2 encode MYB related protein and AS2-domain containing protein, respectively and may regulate transcription. These genes are involved in the determination of axes of leaves of Arabidopsis thaliana. To know the gene regulation in the leaf development, expression profile among wild-type, as1 and as2 mutants and AS2 overexpression plants were compaired. shoot apices from as1-1, as2-1, AS2 overexpressing, and wild type embryos

Analysis of genes regulated by AS2 and TOP1

Project description:AS2 encode AS2-domain containing protein and may regulate transcription. AS2 is involved in the determination of axes of leaves of Arabidopsis thaliana. Type IB DNA topoisomerase (TOP1α) gene has genetic interaction with AS1 and AS2 and is involved in repression of leaf polarity genes. To know the gene regulation in the leaf development, expression profile among wild-type and as2 mutant treated with and without 10-hydroxyl substituted camptothecin (10H-CPT), a specific TOP1 inhibitor, were compared

KIMAT1 and HIF1A-As2 silencing RNA-seq

Project description:In our study, we valided the important oncogeneic roles of KIMAT1 and HIF1A-As2 in non-small cell lung cancer. We used custom designed GapmeRs to silence the KIMAT1 and HIF1A-As2 in H1299 and performed RNA-seq. 11389 and 7767 genes were regulated by KIMAT1 and HIF1A-As2, respectively.

Analysis of genes regulated by AS2 and RH10 at 22, 26°C

Project description:AS2 encodes a protein containing AS2 domain and epigenetically regulate transcription. RH10 encodes an ortholog of human DEAD-box RNA helicase DDX47. These genes are involved in the formation of axes of leaves of Arabidopsis thaliana. To know the gene regulation in the leaf development, expression profile among wild-type, as2, rh10 and as2 rh10 double mutant plants were compared.

Chromatin states in glioblastoma stem cells (HOXA-AS2 depletion)

Project description:Glioblastoma multiform account for about half of all gliomas and are the most deadly and aggressive forms. Its therapeutic resistance and tumor relapse rely on a subpopulation of cells, the so-called Glioma-stem Cells (GSCs). Here, we investigated for the role of the long non-coding RNA HOXA-AS2 in GSC biology by conducting descriptive and functional analyses of glioma samples classified according to their isocitrate dehydrogenase (IDH1) gene mutation status, and of glioma stem cells. We found that HOXA-AS2 is overexpressed only in aggressive (IDHwt) glioma and GSC. Sh-RNA-based depletion of HOXA-AS2 affects GSC both at the cellular and molecular levels with a decrease in proliferation and altered expression of several hundreds of their genes. Integrative analysis revealed that these changes is expression are not associated to changes in DNA methylation or chromatin signature at the promoter of most deregulated genes following HOXA-AS2 silencing in GSC, supporting a post-transcriptional regulation. In addition, transcription factor motif enrichment and correlation analyses sustained that HOXA-AS2 affect, directly or indirectly, expression of key transcription factors of GCS biology, including E2F8, E2F1, STAT1 and ATF3 to, in fine, contributes to their pathological status by promoting proliferation and modulating the inflammation pathway of Glioma Stem Cell.
