Genome-scale deconvolution of RNA structure ensembles

ABSTRACT: RNA structure heterogeneity is a major challenge when querying RNA structures with chemical probing. We introduce DRACO, an algorithm for the deconvolution of coexisting RNA conformations from mutational profiling experiments. Analysis of the SARS-CoV-2 genome using dimethyl sulfate mutational profiling with sequencing (DMS-MaPseq) and DRACO, identifies multiple regions that fold into two mutually exclusive conformations, including a conserved structural switch in the 3′ untranslated region. This work may open the way to dissecting the heterogeneity of the RNA structurome.

DMS-MaPseq: A genome-wide or targeted approach for RNA structure probing in vivo

Project description:Here we present dimethyl sulfate mutational profiling with sequencing (DMS-MaPseq), which encodes DMS modifications as mismatches using a thermostable group II intron reverse transcriptase (TGIRT). DMS-MaPseq yields a high signal-to-noise ratio, can report multiple structural features for each molecule, and allows genome-wide studies as well as focused investigations of low abundance RNAs. We apply DMS-MaPseq to Drosophila melanogaster ovaries—the first experimental analysis of RNA structure in an animal tissue—and demonstrate its utility in the discovery of a functional RNA structure involved in the non-canonical GUG translation initiation of the human FXR2 mRNA. Additionally, we use DMS-MaPseq to compare the in vivo structure of messages in their pre-mRNA and mature forms. These applications illustrate DMS-MaPseq’s capacity to dramatically expand our ability to monitor RNA structure in vivo.

HIV-1 RNA structure and heterogeneity analysis

Project description:The goal of this set of experiments is to determine the structure of HIV-1 NL4-3 and NHG RNA structure using a novel algorithm that allows for the identification of multiple RNA folding conformations. The input data used for this algorithm is DMS-MaPseq data. We focused on two specific areas of the HIV-1 genome, the Rev Response Element (RRE) and A3 splice acceptor site, as well as probing the whole HIV-1 genome. RNA is DMS-modified in vitro and in vivo as indicated. The goal of this data set was to test the novel alternative RNA structure detecting algorithm (DREEM) using RNA molecules with known structures.

DMS-MapSeq Analysis of Antisense Oligonucleotide Binding to lncRNA PANDA

Project description:While various methods exist for examining and visualizing the structure of RNA molecules, dimethyl sulfate-mutational profiling and sequencing (DMS-MaPseq) stands out for its simplicity and versatility. This technique has proven effective for studying RNA structures both in vitro and in complex biological settings. We've updated the protocol for using DMS-MaPseq, and it can also be employed to identify the binding of antisense oligonucleotides (ASOs) to RNA. By applying this updated protocol, we successfully characterized the structural ensemble of the HIV1 Rev Response Element (RRE), along with its two alternative structures. The findings align with previously published research. Additionally, we resolved the structure of the long non-coding RNA PANDA, which was previously unknown. Moreover, we used PANDA as a basis for designing ASOs and confirmed their binding through a substantial decrease in DMS-reactivities at the anticipated ASO binding locations.

RNA duplex map in living cells reveals higher order transcriptome structure

Project description:RNA has the intrinsic property to base pair, forming complex structures fundamental to its diverse functions. Here we develop PARIS, a method based on reversible psoralen-crosslinking for global mapping of RNA duplexes with near base-pair resolution in living cells. PARIS analysis in three human and mouse cell types reveals frequent long-range structures, higher order architectures, and RNA:RNA interactions in trans across the transcriptome. PARIS determines base-pairing interactions on an individual-molecule level, revealing pervasive alternative conformations. We used PARIS-determined helices to guide phylogenetic analysis of RNA structures, and discovered conserved long-range and alternative structures. XIST, a lncRNA essential for X chromosome inactivation, folds into evolutionarily conserved RNA structural domains that span many kilobases. XIST A-repeat forms complex inter-repeat duplexes that nucleate higher order assembly of the key epigenetic silencing protein SPEN. PARIS is a generally applicable and versatile method that provides novel insights into the RNA structurome and interactome. Cells are crosslinked with AMT and RNA is extracted from cells by RNase digestion. Crosslinked RNA fragments are selected from total RNA by 2D gel electrophoresis. Purified crosslinked RNA duplexes are proximity ligated and crosslinking is reversed. Then the chimeric RNA molecules are converted into cDNA libraries for high-throughput sequencing.

SWI/SNF subunit CHR2 remodels pri-miRNAs via microprocessor component SE to inhibit miRNA production DMS-MaPseq)

Project description:Here we present dimethyl sulfate mutational profiling with sequencing (DMS-MaPseq) prepared from leaves of adult plants in Arabidopsis. Chromatin remodeling factor 2 (CHR2) positively regulates transcription of MIR loci whereas repressing microRNA (miRNA) accumulation in vivo. CHR2 can directly bind to and unwind primary miRNAs (pri-miRNAs) and inhibit their processing; and this inhibition entails its remodeling activity in vitro and in vivo.

Structure-seq2 probing of RNA structure upon amino acid starvation reveals both known and novel RNA switches in Bacillus subtilis

Project description:Here we use Structure-seq2 to probe the in vivo RNA structurome of B. subtilis grown in the presence and absence of amino acids. We show that the change in global RNA structurome is inversely proportional to the change in abundance upon amino acid starvation and that this trend is pronounced in the stringent response and codY regulons. We also use this data to characterize known and novel RNA switches.
