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 …

Small RNAs regulate a wide variety of biological processes by repressing the expression of
target genes at the transcriptional and post-transcriptional levels. To achieve these …

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

Heterochromatin is a key architectural feature of eukaryotic chromosomes, which endows
particular genomic domains with specific functional properties. The capacity of …

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 …

Hepatocellular carcinoma (HCC) is a leading lethal malignancy worldwide. However, the
molecular mechanisms underlying liver carcinogenesis remain poorly understood. Over the …

Diverse classes of RNA, ranging from small to long non-coding RNAs, have emerged as key
regulators of gene expression, genome stability and defence against foreign genetic …

The biogenesis of the RNA payload of mature sperm is of great interest, because RNAs
delivered to the zygote at fertilization can affect early development. Here, we tested the …

Inheritance of genomic DNA underlies the vast majority of biological inheritance, yet it has
been clear for decades that additional epigenetic information can be passed on to future …

Discoveries over the past decade portend a paradigm shift in molecular biology. Evidence
suggests that RNA is not only functional as a messenger between DNA and protein but also …
