title: Transductional and transcriptional targeting of cancer cells using genetically engineered viral vectors.
abstract: Gene delivery vectors, including adenovirus (Ad) and adeno-associated virus (AAV), are inefficient and non-selective for cancer due to low levels of viral receptors with high levels on other tissues, including liver. We tested Ads and AAVs with the SIGYPLP-targeting peptide inserted into virus capsids for transduction in a panel of cancer cells. Six of twelve lines (C8161, PC-3, G-CCM, MKN-45, LnCAP and A549) were transduced, independently of native viral tropism. Furthermore the candidate cancer gene therapy promoter FLT-1 was active in three of these six cell lines. This offers the potential for dual targeting of selected cancer cells.
