Mild and ultrafast GLORI enables absolute quantification of m6A methylome from low-input samples

Project description:Methods that enable absolute quantification of N6-methyladenosine (m6A) RNA modification have emerged as powerful tools in the field of epitranscriptomics. We previously reported GLORI, a chemical-assisted approach firstly achieved quantitatively transcriptome-wide m6A measurement at single-base resolution. Despite its advantages, GLORI suffers from lengthy reaction time and severe RNA degradation. Here, we present two updated GLORI approaches: GLORI 2.0 is an ultra-fast and mild version that preserves RNA integrity and enhances sensitivity for both transcriptome-wide and locus-specific m6A detection; GLORI 3.0 further utilizes a novel reverse transcription-silent carrier RNA to achieve high-quality m6A quantification from ~ 1,000 cells. Using limited RNA input extracted from single mouse dorsal hippocampus, we measure m6A methylome in the synaptic and cytoplasmic fractions and reveal a high modification level in synapse-related gene sets. We envision that the updated GLORI methods will greatly expand the applicability of absolute quantification of m6A in biology.

Transcriptome-wide profiling and quantification of N6-methyladenosine by enzyme-assisted adenosine deamination [site_specific_quantification]

Project description:We report evolved TadA-assisted N6-methyladenosine sequencing (eTAM-seq), an enzyme-assisted sequencing technology for quantitative, base-resolution profiling of m6A. eTAM-seq functions by global adenosine deamination, enabling detection of m6A as persistent A. We demonstrate adenosine-to-inosine (I) conversion rates up to 99% using a hyperactive TadA variant. With eTAM-seq, we profile and quantify m6A in the whole transcriptomes of HeLa cells and mouse embryonic stem cells (mESCs), with simultaneous deconvolution of the transcriptome and epitranscriptome. Further, we showcase deep sequencing-free, site-specific m6A quantification with as few as 10 cells, an input demand that is at least 4 orders of magnitude lower than existing methods. Collectively, eTAM-seq enables sensitive detection and faithful quantification of m6A with limited RNA input, representing a novel solution to deciphering the epitranscriptome.

Absolute quantification of single-base m6A methylation in the mammalian transcriptome

Project description:To investigate the m6A methylation in the mammalian transcriptome, we developed a quantitative method, names GLORI, that could detect m6A stoichiometry at single-base resolution. We then performed GLORI on cells with different treatment, such as stress, knockdown and inhibitor. We next analysis m6A methyloms of different celllines and cells under different treatment to investigate the fuctional role of m6A.

DART-seq: an antibody-free method for global m6A detection

Project description:m6A is a widespread RNA modification which plays important roles in the regulation of gene expression. Methods for the global detection of m6A rely on immunoprecipitation of methylated transcripts using m6A antibodies. However, these methods are costly and require large amounts of input RNA, making them prohibitive for many experiments. Here, we describe DART-seq, an antibody-free method for m6A detection which enables transcriptome-wide mapping of m6A residues using low amounts of input material. DART-seq can be used to obtain global m6A maps using as little as 10 nanograms of total RNA and at single-molecule resolution. This method offers several improvements over current techniques and will facilitate detection of m6A in limiting cell and tissue types.

Small Molecule-Catalyzed Deamination: Applications in Transcriptome-Wide Profiling of N6-Methyladenosine in RNA (Arabidopsis)

Project description:We present a novel N-nitrosation strategy for deamination capable of tolerating DNA/RNA biological macromolecules under mild conditions. A cooperative catalysis combining a carbonyl organocatalyst with a Lewis acid catalyst facilitates the formation of a C-nitro intermediate from a primary amine, which, upon rearrangement into N-nitrosamine, leads to selective deamination of unsubstituted canonical DNA/RNA bases under mild conditions. We employed this new approach to deamination of adenine into hypoxanthine, read as guanine by reverse transcriptases or DNA polymerases, while N6-methyladenosine (m6A) sites resist deamination and remain identified as adenine. We therefore report a chemically mild, low-input detection method for adenosine methylation sequencing at base resolution, named Chemical cooperative catalysis-Assisted for m6A sequencing (CAM-seq).
