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.
