Regulation of gene expression in mammalian mitochondria by microRNAs is reported by Zhang et al. During muscle cell differentiation, localization of a miRNA is increased within mitochondria, where it interacts with Ago2 to selectively activate translation of mtDNA-encoded mRNAs. The findings represent a new mitochondrial regulatory pathway and a potentially powerful means to purposefully manipulate mtDNA expression.
