A new interface to study RNA biology

Phys · · 289 words · By Myreille Larouche

Researchers at the Université de Montréal's Institute for Research in Immunology and Cancer have created RIMap-RISC, a new database for modeling interactions between microRNAs and messenger RNAs. The tool is designed to assist in basic biological research and the study of complex diseases like cancer by integrating structural molecular information.
