PIWI-interacting RNAs (piRNAs) are a class of small non-coding RNAs that associate with
proteins of the PIWI clade of the Argonaute family. First identified in animal germ line cells …

In animals, PIWI-interacting RNAs (piRNAs) of 21–35 nucleotides in length silence
transposable elements, regulate gene expression and fight viral infection. piRNAs guide …

MicroRNAs (miRNAs) are short, regulatory RNAs that act as post-transcriptional repressors
of gene expression in diverse biological contexts. The emergence of small RNA-mediated …

MicroRNAs (miRNAs) are∼ 22 nt RNAs that direct posttranscriptional repression of mRNA
targets in diverse eukaryotic lineages. In humans and other mammals, these small RNAs …

PIWI-interacting RNAs (piRNAs) and their associated PIWI clade Argonaute proteins
constitute the core of the piRNA pathway. In gonadal cells, this conserved pathway is crucial …

3′-untranslated regions (3′-UTRs) are the noncoding parts of mRNAs. Compared to
yeast, in humans, median 3′-UTR length has expanded approximately tenfold alongside …

We describe an update of MirGeneDB, the manually curated microRNA gene database.
Adhering to uniform and consistent criteria for microRNA annotation and nomenclature, we …

To connect human biology to fish biomedical models, we sequenced the genome of spotted
gar (Lepisosteus oculatus), whose lineage diverged from teleosts before teleost genome …

Transposable element (TE)-derived sequences are ubiquitous in most eukaryotic genomes
known to date. Because their expression and mobility can lead to genomic instability …

PIWI-interacting RNAs (piRNAs) are a class of small RNAs that are 24–31 nucleotides in
length. They associate with PIWI proteins, which constitute a germline-specific subclade of …
