Dear Editor, PIWI-interacting RNAs (piRNAs) are germ cell-specific small non-coding RNAs that are essential for silenc- ing transposable elements. Substantial efforts in the past decade have led to an understanding...

The piRNA machinery is known for its role in mediating epigenetic silencing of transposons. Recent studies suggest that this function also involves piRNA-guided cleavage of transposon-derived transcripts. As many piRN...
piRNAs, a class of small non-coding RNAs associated with PIWI proteins, have broad functions in germline development, transposon silencing, and epigenetic regulation. In diverse organisms, a subset of piRNAs derived f...

As central components of RNA silencing, small RNAs play diverse and important roles in many biological processes in eukaryotes. Aberrant reduction or elevation in the levels of small RNAs is associated with many devel...
