A novel human artificial chromosome gene expression system using herpes simplex virus type 1 vectors.

ABSTRACT: Human artificial chromosome (HAC) vectors are an important gene transfer system for expression and complementation studies. We describe a significant advance in HAC technology using infectious herpes simplex virus type 1 (HSV-1) amplicon vectors for delivery. This highly efficient method has allowed gene-expressing HACs to be established in glioma-, kidney- and lung-derived cells. We also developed an HSV-1 hypoxanthine phosphoribosyltransferase (HPRT) HAC vector, which generated functional HPRT-expressing HACs that complemented the genetic deficiency in human cells. The transduction efficiency of the HSV-1 HAC amplicons is several orders of magnitude higher than lipofection-mediated delivery. Studies on HAC stability between cell types showed important differences that have implications f
