Research Abstract

In this proect, we tried to develop non-standard cyclic peptides that can inhibit the maturation of miRNA precursor by using RaPID display method, which is a combination of genetic code reprogramming and mRNA display. So far, we have successfully obtained several cyclic peptides that have binding affinity to miR-21 precursor. Evaluations of specificity and binding affinity of the peptides are under way.
