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 …

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 …

The PIWI-interacting RNA (piRNA) pathway is a conserved defense mechanism that protects
the genetic information of animal germ cells from the deleterious effects of molecular …

Cytosine DNA methylation is a stable epigenetic mark that is crucial for diverse biological
processes, including gene and transposon silencing, imprinting and X chromosome …

PIWI-interacting RNAs (piRNAs) are a distinct class of small non-coding RNAs that form the
piRNA-induced silencing complex (piRISC) in the germ line of many animal species. The …

Non-coding RNAs generally form ribonucleoprotein (RNP) complexes with their partner
proteins to exert their functions. Small RNAs, including microRNAs, small interfering RNAs …

The silkworm Bombyx mori uses a WZ sex determination system that is analogous to the one
found in birds and some reptiles. In this system, males have two Z sex chromosomes …

Sex hormones and their receptors play critical roles in the development and progression of
the breast and prostate cancers. Here we report that a novel type of transfer RNA (tRNA) …

This is the 4th edition of a book that was initiated with the annotation of the function of all the
genes in the most commonly studied baculovirus, AcMNPV. It has been almost six years …
