 AB    The expression of human immunodeficiency virus type 1 (HIV-1) in
       infected cells is induced (or enhanced) by a number of agents including
       phorbol myristate acetate (PMA), phytohemagglutinin (PHA), certain
       infectious agents, certain cytokines, and ultraviolet light. ACH2 cells
       represent latently HIV-1-infected T-cells, which produce only a low
       level of HIV-1 in vitro. We found that various anti-cancer agents
       including 5-azacytidine (5-AZC), 5-fluorouracil (5-FU), methotrexate,
       cytosine arabinoside, and vinblastine potentiated the expression of
       HIV-1 in ACH2 cells. There was no evidence of altered DNA methylation
       patterns in ACH2 cells cultured with 5-FU unlike with 5-AZC. The
       NF-kappa B binding activity was found to be enhanced in ACH2 cells
       exposed to 5-FU (but not in those exposed to 5-AZC) as assessed by the
       mobility shift assay using an oligonucleotide containing two NF-kappa B
       binding sites. These data suggest that the use of certain anti-cancer
       agents may induce (or enhance) the expression of HIV-1.
