I t was discovered that there were some data irregularities in the article entitled “Site-specific transgene integration in the human genome catalyzed by ϕBT1 phage integrase” by Li Chen and Savio L.C. Woo (Human Gene Therapy, February 2008, 19(2):143–151).

Dr. Savio L.C. Woo has reported this instance to the Institutional Research Integrity Committee and requested a retraction of their article from Human Gene Therapy and sincerely apologize to their colleagues.
