Development of novel therapeutic approach using gene delivery method for treatment of cardiovascular disease

Antisense and siRNA, modified with BNA/LNA, have been developed under the collaboration with Professor Satoshi Obika (Univ. of Osaka) for the treatment of severe hypercholesterolemia, especially FH. The novel nucleic acid drugs have been shown to have extremely high activity in vivo because of their very high resistance activity against nuclease and extremely high affinity to the target RNA. The project is now going on to develop cholesterol lowering drugs by suppression of genes related to cholesterol metabolism using BNA/LNA.
