MicroRNA gets down to business

Abstract

Because evolution has conserved miRNAs and enabled them to multitask, researchers are wondering if science is on the edge of a sweeping revolution in which control of a few small molecules could create cascading effects of major importance in complex disease situations. But whereas a few companies have jumped into the miRNA field--most as suppliers of tools and information--the biotech industry seems to be awaiting more information on mechanism and some clarity on the intellectual property situation.
