Morpholinos blocking miRNAs

Citations of papers with Morpholinos blocking miRNA activity are here.

Morpholino oligos can block the activity of microRNAs. Morpholinos complementary to the miRNA guide strand can block activity of the miRNA. Morpholinos can also block the Drosha or Dicer nucleolytic processing sites of primary miRNA or pre-miRNA. Morpholinos can interfere with miRNA activity when targeted to the miRNA's target site (MRE) on mRNA. Gene Tools assists in targeting 25-base Morpholino oligos to miRNAs, ideally using sequence information from the Sanger Institute's miRBase.

Morpholinos are usually targeted to one of these sites (shown on the lower part of figure below):
  • Guide
  • Star
  • Guide Drosha
  • Guide Dicer
  • Star Drosha
  • Star Dicer
Please suggest a target site when requesting design of a Morpholino targeting an miRNA. Also, specify the miRNA to target using the ID format used on the Sanger Institute's miRBase. For example, to specify Danio rerio miRNA 126b-2 write "miR-125b-2".

Targets for Morpholinos on miRNAs: guide, star, guide Dicer, guide Drosha, star Dicer, star Drosha.

Note that Dicer activity is not requred for maturation of all miRNAs. Here is a known case where miRNA maturation is independent of Dicer activity:
Cifuentes D, Xue H, Taylor DW, Patnode H, Mishima Y, Cheloufi S, Ma E, Mane S, Hannon GJ, Lawson ND, Wolfe SA, Giraldez AJ. A novel miRNA processing pathway independent of Dicer requires Argonaute2 catalytic activity. Science. 2010 Jun 25;328(5986):1694-8. Epub 2010 May 6.

Morpholinos can also be targeted to the site on an mRNA where a miRNA binds, called the miRNA response element (MRE). Usually these are found in the 3'-UTR of an mRNA. A Morpholino that binds across an MRE is called a target protector. To design target protector Morpholinos, we need about 60 bases of mRNA sequence centered on the MRE, written mostly in upper case but with the bases complementary to the miRNA seed sequence shown in lower case.

A Gene Tools collaboration with Wigard Kloosterman, first of Ronald Plasterk's lab then Rene Ketting's lab at the Hubrecht Institute in the Netherlands, has shown that Morpholino oligos can strongly inhibit the activity of miRNAs in zebrafish so that, after Morphoino treatment, the miRNA signal from in-situ hybridization and Northern blots is decreased or absent. Knockdowns of miRNA activity have generally used oligos targeting the miRNA guide strand. A Morpholino oligo targeting an miRNA guide strand can interfere with the activity of the miRNA. It is difficult to control for the specificity of the knockdown when using this technique alone. However, Morpholinos targeting the nucleolytic processing sites of an immature miRNA can prevent maturation of the miRNA. This allows sets of nonoverlapping Morpholino oligos targeting a primary miRNA to be used as specificity controls; if two non-overlapping oligos targeting the same miRNA (typically targeting the 5p and 3p sites) produce the same phenotype, this supports the hypothesis that the phenotype is due to knocking down the activity of the targeted miRNA and not due to an off-target effect. These techniques are explored in the following paper:
Kloosterman WP, Lagendijk AK, Ketting RF, Moulton JD, Plasterk RHA. Targeted inhibition of miRNA maturation with morpholinos reveals a role for miR-375 in pancreatic islet development. PLoS Biol. 2007;5(8): e203.
Wigard Kloosterman also describes targeting miRNAs with Morpholinos in his dissertation, The expression and function of microRNAs in vertebrate embryonic development

This is the first published report we've found of data from miRNA knockdown using Morpholinos.
