Non-coding RNAs represent one of the most exciting aspects of current biomedical research. Non-coding RNAs include long non-coding RNAs (lncRNAs) which are generally longer than 200 nucleotides (nt) ...

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: ...

We like to think of evolution as a fine-tuning process, one that whittles away genetic redundancies. The only problem is, we are not fine-tuned machines. Our bodies are chock-full of parts that either ...

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 ...

Biologists recently published two studies on the PIWI pathway, exploring how PIWI proteins distinguish transposons from normal DNA and how transposable elements slip past and fool the PIWI pathway. We ...
