Abstract excerpt
The woodchuck hepatitis virus posttranscriptional regulatory element (WPRE) is widely used in retroviral gene transfer vectors. However, this element contains an open-reading frame (ORF) encoding a truncated peptide of the woodchuck hepatitis virus X protein (WHX). Because we are developing a lentiviral vector for the gene therapy of Wiskott-Aldrich syndrome (WAS), we evaluated whether the WPRE was needed in the...
