title: Let me count the ways: mechanisms of gene regulation by miRNAs and siRNAs.
abstract: The downregulation of gene expression by miRNAs and siRNAs is a complex process involving both translational repression and accelerated mRNA turnover, each of which appears to occur by multiple mechanisms. Moreover, under certain conditions, miRNAs are also capable of activating translation. A variety of cellular proteins have been implicated in these regulatory mechanisms, yet their exact roles remain largely unresolved.
