MiRNAs sequence of macrophages derived exosoms in WT group and Roquin-1 san:san group.

ABSTRACT: We reported the function of Roquin-1 in the miRNA-sorting of macrophages derived exosomes. At first, we used the supernatant of 929 cells to culture the bone marrow derived macrophages (BMDM) from bone marrow cells of WT and Roquin-1 san:san mice. Then, we isolated the macrophages derived exosomes by ultracentrifugation. At last, we performed Next-generation sequencing to detect the differences of miRNA-sorting between WT and Roquin-1 macrophages derived exosomes.

Analysis of Roquin targetome during HCMV infection

Project description:To investigate how Roquin regulates cellular transcripts during Human cytomegalovirus (HCMV) infection, we examined the levels of cellular transcripts in cells treated control or Roquin-targeting siRNA during HCMV replication. Also, we performed Roquin crosslinking and immunoprecipitation followed by high-throughput sequencing (Roquin CLIP-seq) in HCMV-infected cells to identify which transcripts are directly bound by Roquin.

Roquin promotes constitutive mRNA decay via a conserved class of stem-loop recognition motifs.

Project description:The degradation of TNFM-NM-1 mRNA is critical for restricting TNFM-NM-1 synthesis and involves a constitutive decay element (CDE) in the 3M-bM-^@M-^Y untranslated region of the mRNA. We demonstrate that the active CDE is a stem-loop RNA motif that is recognized by the RNA-binding protein Roquin. Deep sequencing of Roquin-associated mRNAs identified CDE-containing mRNAs as the primary targets of Roquin on a transcriptome-wide scale. Expression profiles of LPS treated Raw264.7 cells (input), after Roquin IP or control IP were generated by deep sequencing, in three biological replicates, using Illumina HiSeq 2000.

Roquin suppresses PI3K-mTOR signaling to control T cell differentiation and Treg effector function

Project description:Roquin proteins are required to preclude spontaneous T cell activation and aberrant T follicular helper (Tfh) or T helper 17 (Th17) differentiation. Here, we show that deletion of Roquin encoding alleles in regulatory T cells (Tregs) also caused the activation of conventional T cells. These Tregs exhibited a follicular Treg phenotype, CD25 downregulation and could not protect from colitis. Mechanistically, Roquin was required for full expression and activity of Pten and Foxo1, two essential signaling molecules in Tregs and effector T cells. Roquin upregulated Pten by interfering with miR-17~92 binding to an overlapping cis-element in the Pten 3' UTR and downregulated the Foxo1-specific E3 ubiquitin ligase Itch. Loss of Roquin enhanced mTOR signaling and global protein synthesis, while inhibition of PI3K or mTOR in Roquin-deficient CD4+ T cells corrected increased Tfh and Th17 differentiation. Thereby, the control of PI3K-mTOR signaling by Roquin prevents autoimmunity through T cell-intrinsic and Treg-mediated regulation.

Roquin promotes constitutive mRNA decay via a conserved class of stem-loop recognition motifs.

Project description:The degradation of TNFα mRNA is critical for restricting TNFα synthesis and involves a constitutive decay element (CDE) in the 3’ untranslated region of the mRNA. We demonstrate that the active CDE is a stem-loop RNA motif that is recognized by the RNA-binding protein Roquin. Deep sequencing of Roquin-associated mRNAs identified CDE-containing mRNAs as the primary targets of Roquin on a transcriptome-wide scale.

Expression data from CD44loCD8+ T cells of sanroque versus wild-type mice

Project description:We used microarrays to detect the primary changes caused by the 'san' mutation in Roquin gene by comparing the gene expression profiles of naive (CD44lo) CD8+ T cell population. Sorted CD44loCD8+ T cells of age-matched sanroque (Roquinsan/san) and wild-type (Roquin+/+) mice in C57BL/6 background were subjected to RNA extraction and hybridization on Affymetrix microarrays.

RNA-binding preference of the Roquin-1 CCCH-type zinc finger

Project description:Zinc finger (ZnF) domains are widespread RNA-binding domains, recognizing single stranded and double stranded RNAs. Together with other RNA-binding domains, ZnFs enhance the affinity and specificity of RNA-binding proteins (RBPs). The ZnF-containing RBP Roquin controls mRNA decay by recognizing stem-loop elements in the 3'-UTR of its target mRNAs. Stem-loop elements are bound in a shape-specific manner by the unique ROQ domain with nanomolar affinity. The ZnF was suggested to play an essential role in RNA decay by Roquin. However, its RNA motif preference was not investigated so far. Here, we use RBNS to elucidate the RNA binding preference of the isolated Roquin-1 ZnF domain. We find that the ZnF preferentially recognizes single-stranded AU-rich elements (ARE).

Combined disruption of T cell inflammatory regulators Regnase-1 and Roquin-1 enhances antitumor activity of engineered human T cells

Project description:To investigate the effect of Regnase-1 and/or Roquin-1 disruption in engineered primary human T cells, we produced CAR-T cells and TCR-T cells with single genetic disruption of Regnase-1, Roquin-1, or dual disruption of Regnase-1 and Roquin-1. We then performed differential gene expression analysis using data obtained from bulk RNA-seq of 3 different biological donors at baseline.

The RNA-binding proteins Roquin-1 and Regnase-1 interact and cooperate to prevent autoimmunity

Project description:This study aimed to analyze the transcriptomic changes occuring after knockout of alleles encoding for the RNA-binding proteins Roquin-1 and Roquin-2 (DKO), Regnase-1 (KO) or a combination of all three (TKO) in Th1 cells without or after restimulation with anti-CD3/28 antibodies. Data analysis revealed that in unstimulated as well as restimulated T cells of all three knockout genotypes a number of genes is differentially expressed compared to WT cells, with the strongest deregulation seen in TKO cells. A comparison of gene expression changes of all three genotypes indicated that cooperativity of Roquin and Regnase-1 is the prevalent mode of target regulation.
