  • Title: Enhanced expression of transgenes from adeno-associated virus vectors with the woodchuck hepatitis virus posttranscriptional regulatory element: implications for gene therapy.
    Author: Loeb JE, Cordier WS, Harris ME, Weitzman MD, Hope TJ.
    Journal: Hum Gene Ther; 1999 Sep 20; 10(14):2295-305. PubMed ID: 10515449.
    Abstract:
    The woodchuck hepatitis virus posttranscriptional regulatory element (WPRE) evolved to stimulate the expression of intronless viral messages. To determine whether this ability to enhance expression could be useful in nonviral and heterologous viral gene delivery systems, we analyzed the ability of the WPRE to elevate the expression of a cDNA encoding the green fluorescent protein (GFP) in these contexts. We find that the WPRE can stimulate the expression of GFP when the gene is delivered by transfection or transduction with recombinant adeno-associated virus (AAV). Enhancement occurred both during transient expression and when the gene is stably incorporated into the genome of target cells. This enhancement required that the WPRE be located in cis within the GFP message, and was observed in both transformed cell lines and primary human fibroblasts. These results demonstrate that the WPRE will be an effective tool for increasing the long-term expression of transgenes in gene therapy.
