Research Abstract

We constructed adenovirus vector which express artificial miRNA targeting MDM2. Infection with this vector and vector which co-express p53 and artificial miRNA targeting p21 enhanced apoptosis more efficiently in cancer cells. This result suggests that adenovirus-mediated transduction of p53 and miRNAs targeting anti-apoptotic p53 target genes is useful for therapy of human cancers.
