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) ...

Scientists are shedding new light on a little-known biological system that could help unlock the full potential of stem cell therapy, one of the most promising areas of modern medicine. A new review ...

Animal germ line cells, such as sperm and ova, protect their genomes against transposon-inflicted damage via an immune system operated by a family of proteins called Piwi and Piwi-interacting RNA ...

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 ...

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 ...

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 ...
