title: Liposome-mediated gene transfer into human basal cell carcinoma.
abstract: Direct intralesional injection of DNA encoding interferon-alpha2 (IFN-alpha2) was used in an effort to sustain local protein delivery for the treatment of human basal cell carcinoma (BCC). A novel model to study this malignancy was established by transplantation of human BCC tissue on to immunodeficient mice with a relatively high rate of engraftment and stable phenotype for superficial BCC (20 of 25; 80%). Gene transfer was significantly increased by using DNA liposome complexes (lipoplexes). Recombinant gene expression was detected predominantly in the epidermis and, to a lesser extent, in the dermis. Gene transfer of IFN-alpha2 using this method resulted in sustained production of IFN-alpha2 protein and increased expression of a known IFN-inducible gene, the class II major histocompatibility (MHC) antigen, and induced BCC regression, presumably through a non-immune mechanism. Intralesional injection of DNA lipoplexes encoding IFN-alpha protein may therefore be applicable to the treatment of cutaneous BCC.
