abstract：:Piwi-interacting RNAs (piRNAs) were reported in 2006 as a novel class of small non-coding RNAs associated with Piwi proteins of the Argonaute/Piwi family. Recent studies have revealed not only the biogenesis of piRNAs and their roles in transposon silencing, but also the function of the Piwi-piRNA pathway in epigeneti...
