Gene regulation in oocytes relies heavily on poly(A) tail-length changes. Here, the authors develop PAL-AI, a neural network model that predicts tail-length changes, identifies regulatory motifs, and ...

Abstract. In recent years, RNA has been increasingly recognized for its essential roles in biology, functioning not only as a carrier of genetic informatio

Precise control of microRNA (miRNA) expression is critical during development. An important mechanism of miRNA regulation is target-directed microRNA degradation (TDMD), a pathway in which the binding...

There are hundreds of TV apocalypses to choose from, but The Eternaut, a fresh and compelling adaptation of a classic Argentinian comic book series, is the one to pick, says Bethan Ackerley

Kim et al. uncover a role for U1 snRNP in regulating internal promoter activity. Beyond its canonical role in splicing, U1 snRNP suppresses premature polyadenylation, enabling upstream transcription t...

MicroRNAs (miRNAs) associate with Argonaute (AGO) proteins to serve as guides, directing binding to partially complementary sites in mRNAs, ultimately causing post-transcriptional repression. Compleme...

Mammalian cells present RNA-binding proteins on the cell surface that form clustered domains containing glycoRNAs.

Circular RNAs (CircRNAs) are a rediscovered class of RNA species that originate from back-splicing events, which have been reported across all domains of life. Many circRNAs are stable, abundant and …

Mohamed et al. report the cryoelectron microscopy structure of human AGO2 with fully paired guide RNA. Their analysis reveals the structural basis for the slicing activity that drives RNAi, showing that the slicing-competent conformation is achieved by domain movements and RNA-protein contacts distinct from those of conformational intermediates and prokaryotic homologs.

Dimethyl sulfate (DMS) chemical mapping is widely used for probing RNA structure, with low reactivity interpreted as Watson-Crick (WC) base pairs and high reactivity as unpaired nucleotides. Despite i...

The recent Nobel Prizes awarded to Ambros and Ruvkun have refocused attention on microRNAs (miRNAs). The importance of miRNAs for basic science has always been clear, but the application to therapy has lagged behind. This delay has been made even more apparent by the accelerating pace of successful programs using duplex RNAs and antisense oligonucleotides to target mRNA. Why has progress been slow? A clear understanding of how miRNAs function in mammalian cells is obscured by the fact that miRNAs can exert their effects through multiple complex mechanisms. This gap in our knowledge has complicated progress in drug discovery. Better insights into the mechanism of miRNAs, more rigorous definitions of miRNAs, and more powerful tools for establishing the physical contacts necessary for miRNA action are now available. These advances lead to a central question for nucleic acid therapy—can miRNAs be productive targets for drug discovery and development?
