Non-coding, inhibitory microRNAs have emerged as important modulators of cellular gene expression, through a process called RNA interference (RNAi). To date, hundreds of conserved and species-specific microRNAs have been identified in organisms ranging from single-celled algae to humans. Many of these tiny RNAs are now known to play fundamental roles in developmental biology and disease pathogenesis. In addition, RNAi has emerged as a technology useful for manipulating gene expression. In "RNA Interference Techniques," expert researchers present detailed methods for designing and...
