microRNA Microarrays – Biocompare Editorial Article

If PubMed is any guide, the microRNA field is smokin’ hot. Of the nearly 11,100 references that come up in a search for “microRNA,” nearly two-thirds (64%) were published since 2009.

It’s no wonder. Although microRNAs (miRNAs) may be small—they average 22 nucleotides in length—they carry a big stick, biologically speaking. “We can say with confidence that over 60% of human protein-coding genes are conserved targets of miRNAs,” wrote David Bartel and colleagues in 2009. [1]

To date, some 16,772 miRNAs have been discovered and logged in miRBase, including 1,424 in humans. The question for researchers probing these molecules’ biology is, which miRNAs are active under a given set of experimental conditions, and how does that pattern change in the dynamic cellular environment?
