Protocol for base resolution mapping of ac4C using RedaC:T-seq.

ABSTRACT: N4-acetylcytidine (ac4C) is an mRNA modification catalyzed by the enzyme N-acetyltransferase 10 (NAT10), with position-dependent effects on mRNA translation. This protocol details a procedure to map ac4C at base resolution using NaBH₄-induced reduction of ac4C and conversion to thymidine followed by sequencing (RedaC:T-seq). Total RNA is ribodepleted and then treated with NaBH₄ to reduce ac4C to tetrahydro-ac4C, which specifically alters base pairing during cDNA synthesis, allowing the detection of ac4C at positions called as thymidine following Illumina sequencing. For complete details on the use and execution of this protocol, please refer to Arango et al. (2022).¹.

Base-pair-resolution genome-wide mapping of active RNA polymerases using precision nuclear run-on (PRO-seq).

Project description:We provide a protocol for precision nuclear run-on sequencing (PRO-seq) and its variant, PRO-cap, which map the location of active RNA polymerases (PRO-seq) or transcription start sites (TSSs) (PRO-cap) genome-wide at high resolution. The density of RNA polymerases at a particular genomic locus directly reflects the level of nascent transcription at that region. Nuclei are isolated from cells and, under nuclear run-on conditions, transcriptionally engaged RNA polymerases incorporate one or, at most, a few biotin-labeled nucleotide triphosphates (biotin-NTPs) into the 3' end of nascent RNA. The biotin-labeled nascent RNA is used to prepare sequencing libraries, which are sequenced from the 3' end to provide high-resolution positional information for the RNA polymerases. PRO-seq provides much higher sensitivity than ChIP-seq, and it generates a much larger fraction of usable sequence reads than ChIP-seq or NET-seq (native elongating transcript sequencing). Similarly to NET-seq, PRO-seq maps the RNA polymerase at up to base-pair resolution with strand specificity, but unlike NET-seq it does not require immunoprecipitation. With the protocol provided here, PRO-seq (or PRO-cap) libraries for high-throughput sequencing can be generated in 4-5 working days. The method has been applied to human, mouse, Drosophila melanogaster and Caenorhabditis elegans cells and, with slight modifications, to yeast.

Base-resolution profiling of active DNA demethylation using MAB-seq and caMAB-seq.

Project description:A complete understanding of the function of the ten-eleven translocation (TET) family of dioxygenase-mediated DNA demethylation requires new methods to quantitatively map oxidized 5-methylcytosine (5mC) bases at high resolution. We have recently developed a methylase-assisted bisulfite sequencing (MAB-seq) method that allows base-resolution mapping of 5-formylcytosine (5fC) and 5-carboxylcytosine (5caC), two oxidized 5mC bases indicative of active DNA demethylation events. In standard bisulfite sequencing (BS-seq), unmodified C, 5fC and 5caC are read as thymine; thus 5fC and 5caC cannot be distinguished from C. In MAB-seq, unmodified C is enzymatically converted to 5mC, allowing direct mapping of rare modifications such as 5fC and 5caC. By combining MAB-seq with chemical reduction of 5fC to 5hmC, we also developed caMAB-seq, a method for direct 5caC mapping. Compared with subtraction-based mapping methods, MAB-seq and caMAB-seq require less sequencing effort and enable robust statistical calling of 5fC and/or 5caC. MAB-seq and caMAB-seq can be adapted to map 5fC/5caC at the whole-genome scale (WG-MAB-seq), within specific genomic regions enriched for enhancer-marking histone modifications (chromatin immunoprecipitation (ChIP)-MAB-seq), or at CpG-rich sequences (reduced-representation (RR)-MAB-seq) such as gene promoters. The full protocol, including DNA preparation, enzymatic treatment, library preparation and sequencing, can be completed within 6-8 d.

Protocol for detecting m5C RNA modification at single-base resolution using m5C-TAC-seq

Project description:Here we report m5C-TAC-seq, a base-resolution sequencing method to directly detect m5C sites without affecting unmodified C. In m5C-seq, we combined TET-mediated oxidation of RNA m5C to f5C with the selective chemical labeling reaction of f5C, enabling both pre-enrichment of m5C-containing RNA and a m5C-to-T transition in reverse transcription. m5C-seq identifies 2,500 sites in the transcriptome of HeLa and 768 sites in the transcriptome-wide of HEK293T. In addition, taking advantage of barcoding and pooling strategy, m5C-seq detected differential m5C sites upon specific methyltransferases depletion in mESCs and dynamically regulated m5C sites under cell fate transition. Moreover, we also detected 215 sites in chromatin-associated RNAs, demonstrating that portion of m5C sites can be co-transcriptionally catalyzed and the existence of m5C methylations in repeat RNAs.

Quantitative sequencing using BID-seq uncovers abundant pseudouridines in mammalian mRNA at base resolution.

Project description:Functional characterization of pseudouridine (Ψ) in mammalian mRNA has been hampered by the lack of a quantitative method that maps Ψ in the whole transcriptome. We report bisulfite-induced deletion sequencing (BID-seq), which uses a bisulfite-mediated reaction to convert pseudouridine stoichiometrically into deletion upon reverse transcription without cytosine deamination. BID-seq enables detection of abundant Ψ sites with stoichiometry information in several human cell lines and 12 different mouse tissues using 10-20 ng input RNA. We uncover consensus sequences for Ψ in mammalian mRNA and assign different 'writer' proteins to individual Ψ deposition. Our results reveal a transcript stabilization role of Ψ sites installed by TRUB1 in human cancer cells. We also detect the presence of Ψ within stop codons of mammalian mRNA and confirm the role of Ψ in promoting stop codon readthrough in vivo. BID-seq will enable future investigations of the roles of Ψ in diverse biological processes.

INSERT-seq enables high-resolution mapping of genomically integrated DNA using Nanopore sequencing.

Project description:Comprehensive characterisation of genome engineering technologies is relevant for their development and safe use in human gene therapy. Short-read based methods can overlook insertion events in repetitive regions. We develop INSERT-seq, a method that combines targeted amplification of integrated DNA, UMI-based correction of PCR bias and Oxford Nanopore long-read sequencing for robust analysis of DNA integration. The experimental pipeline improves the number of mappable insertions at repetitive regions by 4.8-7.3% and larger repeats are processed with a computational peak calling pipeline. INSERT-seq is a simple, cheap and robust method to quantitatively characterise DNA integration in diverse ex vivo and in vivo samples.

Epitranscriptomic mapping of RNA modifications at single-nucleotide resolution using rhodamine sequencing (Rho-seq).

Project description:The recent development of epitranscriptomics revealed a new fundamental layer of gene expression, but the mapping of most RNA modifications remains technically challenging. Here, we describe our protocol for Rho-Seq, which enables the mapping of dihydrouridine RNA modification at single-nucleotide resolution. Rho-Seq relies on specific rhodamine-labeling of a subset of modified nucleotides that hinders reverse transcription. Although Rho-Seq was initially applied to the detection of dihydrouridine, we show here that it is applicable to other modifications including 7-methylguanosine or 4-thiouridine. For complete details on the use and execution of this protocol, please refer to Finet et al. (2022).

Differential expression analysis of RNA-seq data at single-base resolution.

Project description:RNA-sequencing (RNA-seq) is a flexible technology for measuring genome-wide expression that is rapidly replacing microarrays as costs become comparable. Current differential expression analysis methods for RNA-seq data fall into two broad classes: (1) methods that quantify expression within the boundaries of genes previously published in databases and (2) methods that attempt to reconstruct full length RNA transcripts. The first class cannot discover differential expression outside of previously known genes. While the second approach does possess discovery capabilities, statistical analysis of differential expression is complicated by the ambiguity and variability incurred while assembling transcripts and estimating their abundances. Here, we propose a novel method that first identifies differentially expressed regions (DERs) of interest by assessing differential expression at each base of the genome. The method then segments the genome into regions comprised of bases showing similar differential expression signal, and then assigns a measure of statistical significance to each region. Optionally, DERs can be annotated using a reference database of genomic features. We compare our approach with leading competitors from both current classes of differential expression methods and highlight the strengths and weaknesses of each. A software implementation of our method is available on github (https://github.com/alyssafrazee/derfinder).

High-resolution protein-protein interaction mapping using all-versus-all sequencing (AVA-Seq).

Project description:Two-hybrid systems can be used for investigating protein-protein interactions and may provide important information about gene products with unknown function. Despite their success in mapping protein interactions, two-hybrid systems have remained mostly untouched by improvements in next-generation DNA sequencing. The two-hybrid systems rely on one-versus-all methods in which each bait is sequentially screened against an entire library. Here, we developed a screening method that joins both bait and prey as a convergent fusion into one bacterial plasmid vector that can then be amplified and paired-end sequencing by next-generation sequencing (NGS). Our method enables all-versus-all sequencing (AVA-Seq) and utilizes NGS to remove multiple bottlenecks of the two-hybrid system. AVA-Seq allows for high-resolution protein-protein interaction mapping of a small set of proteins and has the potential for lower-resolution mapping of entire proteomes. Features of the system include ORF selection to improve efficiency, high bacterial transformation efficiency, a convergent fusion vector to allow paired-end sequencing of interactors, and the use of protein fragments rather than full-length proteins to better resolve specific protein contact points. We demonstrate the system's strengths and limitations on a set of proteins known to interact in humans and provide a framework for future large-scale projects.
