Functional analysis of microRNA activity in Brugia malayi

Int J Parasitol. 2015 Aug;45(9-10):579-83. doi: 10.1016/j.ijpara.2015.04.004. Epub 2015 May 22.

Abstract

The complement of the Brugia malayi microRNA-71 was inserted into the 3' untranslated region of a reporter plasmid, resulting in a decrease in reporter activity. Mutation of the seed sequence restored activity. Insertion of the 3' untranslated regions from two algorithm-predicted putative target genes into the reporter resulted in a similar decrease in activity; mutation of the predicted target sequences restored activity. These experiments demonstrate that B. malayi microRNA targets may be predicted using current algorithms and describe a functional assay to confirm predicted targets.
