  • Genetic Selection System for Identification of microRNA Target Genes
    • Issued 10/7/2014 as US Pat #8,852,926

      Inventors: Yin-Yuan Mo and Fangting Wu

      Summary: miRNA target determination largely relies on computer-aided algorithms based on the nucleotide base pairing of a miRNA sequence and the 3’-untranslated regions of a potential target gene. However, predicted targets vary from one program to another. Recent evidence also indicates that even perfect base pairing may not predict miRNA-target interactions. This novel system utilizes a specially constructed plasmid that contains a puromycin resistance gene, a resistance gene blocker, and cDNA for a gene of interest. The plasmid is transfected into host cells along with a vector expressing a miRNA. If the cDNA contains a miRNA target, the cells will live in the presence of puromycin. If the cDNA does not contain a miRNA target, the cells will die in the presence of puromycin. This method can be used with cDNAs and miRNAs of interest as a rapid screening tool that provides clear and measurable results. This invention could be sold either as individual plasmids or a kit and would save researchers weeks to months performing individual target validation tests.
