K.K. Farh et al., "The Widespread Impact of Mammalian microRNAs on mRNA repression and evolution," Science, 310:1817-21, Dec. 16, 2005.Expression of mRNA carrying the conserved 7 nt sites matching microRNAs can be strong at developmental stages before microRNA expression but is reduced at a later stage. Genes preferentially expressed at the same time and place as microRNAs have evolved to avoid sites matching the miRNAs by adopting non-conserved sites.Fritz EcksteinMax Planck I
