Piwi, a brown kiwi who lived near a volcano, had a rough couple of months back in 2010, but people are still rejoicing in his recovery. In December 2009, the North Island brown kiwi was found near Mt.

PIWI-interacting RNAs (piRNAs) are a distinct class of small non-coding RNAs that protect the integrity of the genome by silencing transposable elements in both germline and gonadal somatic cells.

PIWI-interacting RNAs (piRNAs) are made from dedicated precursor transcripts that are transcribed from specialized loci. piRNA biogenesis from their precursors involves at least three different steps: ...

PIWI proteins and piRNAs regulate the expression of genes and transposons at both transcriptional and post-transcriptional levels. (1) Sense and antisense piRNA precursor transcripts are produced from ...
