Simultaneous nanopore profiling of mRNA m6A and pseudouridine reveals translation coordination

Project description:N6-methyladenosine (m6A) and pseudouridine (Ψ) are the two most abundant modifications in mammalian mRNA, but the coordination of their biological functions remains poorly understood. We develop a machine learning-based nanopore direct RNA sequencing method (NanoSPA) that simultaneously analyzes m6A and Ψ in the human transcriptome. Applying NanoSPA to polysome profiling, we reveal opposing transcriptomic co-occurrence of m6A and Ψ and synergistic, hierarchical effects of m6A and Ψ on the polysome.

Interferon inducible pseudouridine modification in human mRNA by quantitative nanopore profiling (Nanopore)

Project description:Pseudouridine (Ψ) is an abundant mRNA modification in the mammalian transcriptome, but its function has remained elusive due to the difficulty of transcriptome-wide mapping. We develop nanopore native RNA sequencing for quantitative Ψ analysis that utilizes native content training, machine learning model prediction, and single read coordination. We find interferon inducible Ψ modifications in the interferon stimulated gene transcripts, consistent with a role of Ψ in the efficacy of mRNA vaccines.

m6A in 5â untranslated regions promotes cap-independent translation of mRNA

Project description:N6-methyladenosine (m6A) is a widespread internal RNA modification whose function is poorly understood. Here we report that m6A residues within the 5'UTR promote a novel form of cap-independent translation which is mediated through an interaction between m6A residues and the translation initiation factor, eIF3. We present eIF3a PAR-iCLIP data which demonstrate that eIF3 predominantly binds mRNAs within the 5'UTR. eIF3 binding sites are also in proximity to m6A residues within the 5'UTR of cellular mRNAs. Two replicates of eIF3a PAR-iCLIP in HEK293T cells.

Pseudouridine in small RNAs

Project description:Pseudouridine is an isomer of uridine and is the most common RNA modification in both procaryotes and eucaryotes. It is found in ribosomal, transfer, and other structural RNA as well as in some mRNA and non-coding RNA. We have found abundant pseudouridine in small RNA and their precursors in Arabidopsis.

Knockout of Pseudouridine synthase 1 (PUS1) in mice. [Kidney]

Project description:In an effort to produce a mouse model of Mitochondrial Myopathy with Lactic acidosis and Sideroblastic Anemia (MLASA), we knocked out the gene for Pseudouridine synthase 1 (PUS1), an enzyme that modifies uridine to pseudouridine in many cytoplasmic and mitochondrial tRNAs, as well as other cellular RNAs. The Pus1-/- mice are viable, are born at the expected Mendelian frequency, and are non-dysmorphic. The PUS1 mRNA and certain pseudouridine modifications are absent in cytoplasmic and mitochondrial tRNAs in the Pus1-/- mice. The Pus1-/- mice display reduce exercise capacity at 14 weeks, with alterations in muscle morphology, histology, and physiology. Red gastrocnemius muscle from Pus1-/- mice shows reduced number and size of mitochondria and reduced Cytochrome C oxidase activity. Two-condition, two-color experiment: Mouse wild type PUS1 and homozygous mutant PUS1 kidney tissue samples: 4 biological replicates each.
