AAV Vector Integration Sites in Mouse Hepatocellular Carcinoma

Abstract excerpt

Adeno-associated viruses (AAV) are promising gene therapy vectors that have little or no acute toxicity. We show that normal mice and mice with mucopolysaccharidosis VII (MPS VII) develop hepatocellular carcinoma (HCC) after neonatal injection of an AAV vector expressing b-glucuronidase. AAV proviruses were isolated from four tumors and were all located within a 6-kilobase region of chromosome 12. This locus...
