| Outline of Final Research Achievements |
Intimal hyperplasia (IH) is the main cause of vein graft stenosis or failure after bypass surgery. However, no therapeutic targets for the treatment of IH have been identified. Our recent research using human vein graft samples have been reported that inhibiting the CREB function is a key role to prevent vein graft IH. Threfore, We focused on decoy oligodeoxynucleotide(ODN) transfection as gene therapy strategy of IH. The goals of the present study are to investigate inhibiting effect on CREB function by CRE-decoy ODN and to prevent vascular IH.Transfer of the decoy ODN repressed CRE activity and decreased VSMCs proliferation, and migration significantly, the same as the treatment of DN of CREB.From now on, we will check the therapeutic efficacy of the decoy therapy in mouse model. Transfer of CRE decoy ODN may lead to new clinical approach to IH.
