Imperial College researchers Leandro Castellano and Justin Stebbing report on microRNAs and small interfering RNAs in mammalian tissues. The researchers sifted through hundreds of millions of mouse RNA sequences representing a range of somatic tissues and cell types. The search led to more than five dozen new miRNA coding loci in the mouse genome, including sites producing so-called "mirtrons," or pre-miRNA hairpins produced through intron splicing.
