Recent Review: miRNAs & Cancer

What's on my desk to read today? A recent review on miRNAs and cancer.

This review is not directly relevant to using RNAi for screens, of course. But Fig. 4 is a nice summary of tools for disrupting miRNAs. And I like to try to keep up with aspects of RNA biology, as understanding RNA biology is interlinked with exploiting it as a research tool.
