Constructs containing artificial microRNA target sites have the potential to improve a range of therapeutic strategies that are based on gene delivery or viruses. The same technology can be used for experimental purposes, in animal transgenics and to study the functions of microRNAs.
The development of high-throughput DNA sequencing methods provides a new method for mapping and quantifying transcriptomes — RNA sequencing (RNA-Seq). This article explains how RNA-Seq works, the challenges it faces and how it is changing our view of eukaryotic transcriptomes.
