TWAS-based translational genomics approach identifies IL10RB as the top candidate gene for COVID-19 host susceptibility and severity

Project description:Recent efforts have identified genetic loci that are associated with coronavirus disease 2019 (COVID-19) infection rates and disease outcome severity. Translating these genetic findings into druggable genes that regulate COVID-19 host susceptibility is a critical next step. Using a translational genomics approach that integrates COVID-19 genetic susceptibility variants, multi-tissue genetically regulated gene expression (GReX) and perturbagen signatures, we identify IL10RB as the top key regulator of COVID-19 host susceptibility. In a series of validation steps we show that predicted GReX up-regulation of IL10RB and higher IL10RB expression in COVID-19 patient blood is associated with worse COVID-19 outcomes, and that in vitro IL10RB overexpression is associated with increased viral load and activation of disease-relevant molecular pathways.

GCN2 suppresses TOP mRNA translation via LARP1

Project description:La-related protein 1 (LARP1) has been identified as a key translational inhibitor of terminal oligopyrimidine tract (TOP) mRNAs downstream of the nutrient sensing protein kinase complex, mTORC1. LARP1 exerts this inhibitory effect on TOP mRNA translation by binding to the mRNA cap and the adjacent 5’TOP motif, resulting in the displacement of the eIF4E complex from TOP mRNAs. In the present study, we identify a second nutrient sensing kinase GCN2 that converges on LARP1 to control TOP mRNA translation. GCN2 inhibits TOP mRNA translation via ATF4-dependent transcriptional induction of LARP1 mRNAs and GCN1-mediated recruitment of LARP1 to stalled ribosomes. We performed ATF4 ChIP-seq experiments in both WT and GCN2 KO MEFs with or without leucine deprivation.

eIF4A1 enhances LARP1-mediated translational repression during mTORC1 inhibition

Project description:Eukaryotic translation initiation factor (eIF) 4A — a DEAD-box RNA-binding protein — plays an essential role in translation initiation. Recent reports have suggested helicase-dependent and helicase-independent functions for eIF4A, but the multifaceted roles of eIF4A have not been fully explored. Here, we show that eIF4A1 enhances translational repression during the inhibition of mechanistic target of rapamycin complex 1 (mTORC1), an essential kinase complex controlling cell proliferation. RNA pulldown followed by sequencing revealed that eIF4A1 preferentially binds to mRNAs containing terminal oligopyrimidine (TOP) motifs (TOP mRNAs), whose translation is rapidly repressed upon mTORC1 inhibition. This selective interaction depends on a La-related RNA-binding protein, LARP1. Ribosome profiling revealed that deletion of EIF4A1 attenuated the translational repression of TOP mRNAs upon mTORC1 inactivation. Moreover, eIF4A1 increases the affinity between TOP mRNAs and LARP1 and thus ensures stronger translational repression upon mTORC1 inhibition. Our data show the multimodality of eIF4A1 in modulating protein synthesis through an inhibitory binding partner and provide a unique example of the repressive role of a universal translational activator.

Keratinocyte-derived circulating exosomal miRNAs as a novel biomarker of disease severity in psoriasis

Project description:To reveal the relationship between circulating exosomal miRNAs and the disease severity of psoriasis, we performed next-generation sequencing from plasma exosomes of patients with high psoriasis area and severity index (PASI) score (>10) and low PASI score (<5). We identified 19 differentially expressed exosomal miRNAs that were significantly different between the groups. We validated the top three up-and down-regulated exosomal miRNAs using quantitative real-time PCR.

Genome-wide translational analysis of the effect of acute endurance exercise on mouse gastrocnemius

Project description:Purpose: The aim of this study is to investigate the translational regulation of skeletal muscle during acute endurance exercise. Methods: We used mRNA-Seq and ribosome profiling to examine transcriptional and translational regulation, respectively. Result: There were clear distinctions between the profiles of transcription and translation even at a basal condition. TOP-motif genes were translationally suppressed immediately after the exercise. Other genes, such as Slc25a25 was significantly translationally up-regulated presumably in a mTOR-independent manner. Conclusion: There were diverse regulation between transcription and translation. Although many focused on overall protein synthesis to understand the effect of exercise, translational regulation of individual genes are required. Transcriptional and translational profiles of mouse gastrocnemius with or without acute endurance exercise were generated using Ion PGM sequencer.

Tethered Oligonucleotide-Primed sequencing (TOP-seq): a high resolution economical approach for DNA epigenome profiling

Project description:We describe the development and thorough validation of a new approach for epigenome analysis (named TOP-seq) that is based on a novel concept – combination of selective covalent tagging and targeted genomic sequencing of the genome. The technique reports the modification status of each genomic CpG site by priming the DNA polymerase action from a tethered oligonucleotide probe that is selectively attached to the unmodified CpG sites.

Early gene expression differences in inbred mice predict susceptibility to spontaneous pulmonary adenomas

Project description:We examined if gene expression profiles differed between healthy (tumor-free) mice of strains that are known to have different pulmonary adenoma susceptibility (severity and frequency). Three females of 11 week old mice of 9 (129S1/SvlmJ, A/J, BALB/cJ, C3H/HeJ, C57BL/6J, C57L/J, DBA/2J, KK/HlJ, and MRL/MpJ) strains were selected for RNA extraction and hybridization on GeneChip® Mouse Gene 1.0 ST Arrays (Affymetrix, Santa Clara, CA). Each strain was compared to all other strains (36 unique comparisons total) to identify the most common differentially expressed probe sets among the population. The most common probesets were then compared between strain groups (increased vs. decreased spontaneous pulmonary adenoma frequency and severity).

The LARP1 homolog Slr1p controls the stability and expression of proto-5’TOP mRNAs in fission yeast [RNA-seq]

Project description:Messenger RNAs (mRNAs) in higher eukaryotes that encode highly expressed proteins important for the assembly of the translational apparatus (e.g. ribosomal proteins) often harbour a pyrimidine-rich motif at the extreme 5’ end known as a 5’ terminal oligopyrimidine (5’TOP) sequence. Members of the La-related protein 1 (LARP1) family control 5’TOP expression through a conserved DM15 motif, but the mechanism is not well understood. 5’TOP motifs have not been described in many lower organisms, but fission yeast (and many other single-celled eukaryotes) harbour a LARP1 homolog that also lacks a DM15 motif. In this work, we show that the fission yeast LARP1 homolog, Slr1p, controls the translation and stability of mRNAs encoding proteins analogous to 5’TOP mRNAs in higher eukaryotes, which we thus refer to as proto-5’TOPs. Our data suggest that the LARP1 DM15 motif and the mRNA 5’TOP motif may be features that were scaffolded over a more fundamental mechanism of LARP1 family member-associated control of gene expression that is still utilized in lower systems.
