RNA-seq of Recombinant Mouse Cold-inducible RNA-binding protein(rmCIRP)-treated Naïve CD4+ T cells

ABSTRACT: Cold-inducible RNA-binding protein (CIRP) is a ubiquitous intracellular RNA chaperon, which serves as a damage-associated molecular pattern (DAMP) when released outside the cells upon stimulation by inflammation and infection. It has been shown that CIRP promotes splenic CD4+ and CD8+ T-cell activation in vivo and predisposes CD4+ T cells to a Th1 hyperinflammatory response profile in vitro. However, the effect and underlying mechanisms of CIRP on Th17/Treg differentiation is still unclear. This study reveals the transcriptomic changes of mouse Naïve CD4+ T cells induced by Recombinant Mouse CIRP (rmCIRP) in vitro.

CIRP, a cold-inducible RNA-binding protein, modulates circadian gene expression posttranscriptionally

Project description:In mammalian tissues circadian gene expression can be driven by local oscillators or systemic signals controlled by the master pacemaker in the suprachiasmatic nucleus. Here we show that simulated body temperature cycles, but not peripheral oscillators, can control the rhythmic expression of Cold-Inducible RNA binding Protein (CIRP) in cultured fibroblasts. In turn, loss-of-function experiments indicate that CIRP is required for high amplitude circadian gene expression. The transcriptome-wide identification of CIRP-bound RNAs by a biotin-streptavidin based CLIP-seq procedure revealed several CIRP-bound transcripts encoding circadian oscillator proteins. One of these, CLOCK, accumulated to particularly low levels in CIRP-depleted fibroblasts. Since ectopic expression of CLOCK improved circadian gene expression in these cells, we surmise that CIRP confers robustness to circadian oscillators via the regulation of CLOCK expression.

Rescue Of Dysfunctional Autophagy By Peptide IDR-1018 Attenuates Hyperinflammatory Phenotype Of Cystic Fibrosis Cells (RNA-seq)

Project description:Genome-wide gene expression was measured in peripheral blood mononuclear cells (PBMCs) from patients with cystic fibrosis (CF) after treatment in vitro with the flagellin protein fliC, and/or synthetic peptide IDR-1018 to assess patterns of gene expression. The patterns of gene expression suggest that CF cells have a hyperinflammatory phenotype including dysfunctional autophagy processes. The synthetic peptide IDR-1018 attentuates this hyperinflammatory phenotype. Total RNA was obtained from PBMCs obtained from CF patients after treatment with the fliC flagellin protein (that is known to play a role in CF lung inflammation), and/or the peptide IDR-1018 that has anti-inflammatory properties. Comparison of genes and pathways affected by these treatments indicated the role of autophagy process in CF disease.

A novel oncomicropeptide encoded by DSP-AS1 exhibits proneoplastic properties in lung adenocarcinoma by facilitating YTHDF1-induced translation initiation through mediation of mRNA circularization

Project description:Functional micropeptides can hide inside RNA previously annotated as non-coding, their roles in the tumorigenesis of lung cancer remain largely unknown. Here, combining Ribo-seq, mass spectrometry and bioinformatics, we characterize a 46 amino-acid length oncogenic micropeptide encoded by lncRNA DSP-AS1, that we named Desmoplakin Associated MicroPeptide (DAMP), in lung adenocarcinoma (LUAD). DAMP is aberrantly overexpressed in LUAD and confers an unfavorable prognosis, its pro-neoplastic properties with respect to augmented proliferation, survival and invasiveness were validated in vitro and in vivo. DAMP colocalizes with translation machinery and induces translational reprogramming both by elevating global protein synthesis and by selectively upregulating the translation of mRNA group encoding oncogenic factors in LUAD. Mechanistically, DAMP simultaneously binds cap-binding subunit eIF4G and YTHDF1, a m6A reader that could fuel translation initiation by recruiting eIF3 to methylated mRNA. The above interactions lead to the formation of a “closed loop” between YTHDF1 and eIF4G bridged by DAMP, which makes YTHDF1 to be spatially in proximity with translation initiation complex and successfully loading of ribosomal 40S subunit onto target mRNAs. Targeting DAMP exhibited significant anti-cancer effects in vitro and in vivo. Our findings not only unravel the oncogenic role of a previously unrecognized micropeptide through orchestrating mRNA translation but also provide a strong rationale in the design of anti-cancer therapy targeting translation machinery in LUAD.

Expression data for murine colon carcinoma cell line CT26.WT stimulated with S100a8 or S100a9 recombinant protein

Project description:Damage-associated molecular pattern (DAMP) molecules S100A8 and S100A9 with well-known functions in inflammation, tumor growth and metastasis. It has been found to have promote tumor cell proliferation activity at low concentration . However, the mechanism underlying this remains unclear.

Expression analysis of DamP mRNAs using expressed molecular barcodes

Project description:We have generated 979 yeast strains in which the natural 3' UTR of essential gene mRNAs has been replaced by the same long 1.4 kb artificial 3' UTR (DAmP modification). Nonsense mediated mRNA decay (NMD) of these mRNA reporters was tested by using Agilent barcode microarrays by taking advantage of molecular barcodes introduced just downstream the stop codon during strain construction. We introduced in each DAmP strain either a neutral mutation (deletion of YEL068C) or the deletion of essential factors for NMD: NAM7 and NMD2. The resulting haploid cells were tested for changes in DAmP mRNA levels by comparing an RNA sample with a DNA genomic sample. Differences between the samples indicate the sensibility of the DAmP mRNAs to degradation through NMD. The large scale results were validated by Q-PCR analysis of individual strains. A strong negative correlation between the level of destabilization elicited by a long 3' UTR and the size of the coding sequence suggests that long ORF mRNAs can escape NMD even in the presence of a long 3' UTR. Three samples were analysed and for each sample a technical replicate was performed, starting from the raw cellular material. YEL068C samples represent the reference population while NMD2 and NAM7 samples are the ones important for the analysis. Only a very limited part of the Agilent barcode microarray signal (barcodes corresponding to the “up” tag in the DamP strain) was used for the interpretation of the data.
