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 ...

Many couples struggle with infertility. Contrary to popular belief, men are just as often the cause of an unfulfilled desire for children as women—and genetics play a significant role in this.

Adverse genetic mutations can cause harm and are due to various circumstances. "Jumping genes" are one cause of mutations, but cells try and combat them with a specialized RNA called piRNA. For the ...

You're likely familiar with RNA, the molecule that plays an important role in protein production and gene expression control. Perhaps you're less familiar, however, with PIWI-interacting RNA (piRNA), ...

RNA interference is a conserved biological response to double-stranded RNA that regulates gene expression. The response is mediated by small interfering RNAs (siRNAs), which guide the ...
