Human hepatoma (HepG2) and human umbilical vein endothelial (HUVEC) cells were infected with 1×10e5 (data not shown) or 5×10e5 gc/cell of AAV2/8-TBG-eGFP vectors or vectors encoding eGFP under the control of the ubiquitous chicken beta-actin promoter (AAV2/8-CBA-eGFP). The gene discussed is ACTB; the disease is hepatocellular carcinoma.
