miRNA displacement as a promising approach for cancer therapy

Abstract

microRNA (miRNA) are critical post-transcriptional regulators and key players in diseases development. We demonstrated that non-canonical microRNA Responsive Elements (here MRE-16) could sequester miR-16, dampening miR-16 tumor suppressor function. We developed small oligonucleotides, masking specifically these unusual miR-16 binding sites, that restored miR-16 function. This constitutes a promising targeted approach.
