Up-regulation of HIV-1 transduction in nondividing cells by double-strand DNA break-inducing agents.
Efficient HIV-1 transduction depends on a number of cellular co-factors. Cellular double-strand DNA break (DSB) repair proteins have been proposed, by ourselves and others, to be required for efficient HIV-1 transduction. Expression and/or activity of these DNA repair proteins can be induced by the introduction of DSBs into the host cell genome. HIV-1 transduction was up-regulated by treatment with DSB-inducing agents in both drug-arrested cells and differentiated neuronal cells. The presented data support the hypothesis that DSB repair proteins are involved in the early steps of the retroviral life-cycle.
