  1. ...) demonstrated that introns are not always removed in the order in which they appear in the nascent transcript. Our recent work extended these results by studying posttranscriptional splicing order for three to six consecutive introns (Choquet et al. 2023) using long-read direct RNA nanopore sequencing (Garalde...
  2. ...of a single bacterium Lactobacillus or Bombilactobacillus instead of Gilliamella in GF bees successfully restores the Adar p.482 Ile >Met and the global editing level. Our work demonstrates the complex and dynamic transcriptomic diversity exerted by A-to-I RNA editing and discovers the axis of gut–Lactobacillus/Bombilactobacillus–brain–Adar–global...
  3. ...been reported in studies using long-read sequencing of nascent RNA, 91 where transcripts were found to be either fully spliced or completely unspliced , with a 92 smaller group of transcripts showing a mixture of spliced and unspliced introns (Herzel 93 et al. 2018; Drexler et al. 2020). However, after...

  4. ...critical insights into transcription dynamics. Here, we combine transient transcriptome sequencing with transcription start site sequencing (TT-TSS-seq) to accurately map and quantify transcription initiation sites from nascent transcripts. Because transient metabolic labeling yields low-input RNA, we...
  5. ...motif and coding sequences. METTL2A knockdown alters expression of S100A4 mRNA isoforms, which contains METTL2A-mediated m3C sites. Notably, many transcripts with METTL2A-mediated m3C sites are upregulated upon METTL2A knockdown. We reveal the transcriptome-wide presence of m3C sites in poly(A) RNA...
  6. ...transcript by its GC-content, MFE, and tertiary structure, correlating these with model predictions and empirical sequencing counts (Fig. 4B). Unlike equal-molar spike-ins, natural k-mer counts are influenced by their global overlapping frequency across all isoforms. To isolate the effects of RNA structure...
  7. ..., underscoring the need for a comprehensive functional characterization.Traditional approaches to identify active enhancers often correlate transcription factor binding with chromatin accessibility, RNA polymerase II (RNAPII) recruitment, or enhancer-associated histone modifications (Andersson and Sandelin 2020...
  8. ...on mRNA stability, transcription, and translation efficiency (Mauer et al. 2017; Min et al. 2018; Cesaro et al. 2023). Specifically, m6A reader proteins such as YTHDC1 and YTHDC2, which interact with m6A sites on 3′ UTRs, enhance mRNA stability (Wang et al. 2014; Lee et al. 2021). Our study revealed...
  9. ...a sample, reverse-transcribing it into stable cDNA, and finally sequencing using (mostly) Illumina technology (Bentley et al. 2008). RNA-seq has multiple technical variations, either to identify specific types of transcripts or to characterize other RNA products. For instance, small RNA sequencing (sRNA...
  10. ...: wyzhang@nwpu.edu.cn, tautz@evolbio.mpg.deAbstractThe ability to generate multiple RNA transcript isoforms from the same gene is a general phenomenon in eukaryotes. However, the complexity and diversity of alternative isoforms in natural populations remain largely unexplored. Using a newly developed full...
