Possible target found for boosting microRNA action
Study shows how micro molecules interfere with gene expression.
Tiny fragments of RNA called microRNAs are known to interfere with gene expression, but how? A new study hints that they get involved right at the start of the game — they seem to prevent protein production before it even starts.
The finding, published online this week in Nature, provides a key to understanding how microRNAs dial down the expression of genes, and hints at a new drug target1.
