 AB    Much attention has recently focused on the observation that UV light can
       activate the long terminal repeat (LTR) of the human immunodeficiency
       virus (HIV). Although the mechanism of LTR activation remains obscure,
       several lines of investigation have suggested that it is a result of
       activation of the NF-kappa B transcription factor(s) following signaling
       events related to generalized DNA damage. In this report, we present
       data demonstrating that HIV LTR activation is not a general consequence
       of cellular DNA damage, but rather a process unique to specific
       genotoxic stimuli, and that it does not necessarily depend on activation
       of NF-kappa B. Furthermore, we demonstrate that several of these agents
       can significantly increase HIV replication and accelerate CD4-positive
       lymphocyte cytotoxicity in vitro. These findings, therefore, could have
       clinical significance to AIDS patients with malignancies who are
       undergoing radiotherapy and chemotherapy.
