Abstract

Lentiviral vectors derived from the human immunodeficiency virus-1 (HIV-1) have a higher propensity to transduce nondividing cells compared to vectors based on oncoretroviruses. We report here that genistein, a previously known protein tyrosine kinase (PTK) inhibitor and G2 cell cycle arrest inducer, significantly enhanced lentiviral transduction in a dose-dependent manner. Increased transduction, as measured by vector expression, was seen in a variety of human cell lines, murine primary lymphocytes, and primary human CD34+ peripheral blood progenitor cells as well. Increased vector expression was also associated with an increase in vector DNA copy number, as assessed by quantitative PCR. Genistein-mediated G2 cell cycle arrest, rather than PTK inhibition, appears to be the major factor responsible for increased gene transfer. Genistein also increases cyclophilin A (CypA) protein, a cellular protein important for efficient HIV-1 infection. While we show that CypA-/- Jurkat cells transduce poorly with lentiviral vectors, genistein does increase gene transfer in CypA-deficient cells. CypA and G2 cell cycle arrest appear to be two independent factors important for efficient lentiviral gene transfer. The role of genistein and other G2-arresting agents may be useful for improving the efficiency of lentiviral gene therapy.
