“…Indeed, sodium butyrate, another short-chain fatty acid, unbranched in contrast to VPA, was shown to induce HCMV replication in human endothelial cells (Radsak et al, 1989) and in a human epithelial cell line (Tanaka et al, 1991). This compound had been previously described to induce a variety of morphological and biochemical changes in different cell types (Prasad & Sinha, 1976), and also to stimulate the replication of other herpesviruses, EpsteinBarr virus and herpes simplex virus (Luka et al, 1979;Saemundsen et al, 1980;Ash, 1986) and more recently HIV (Bohan et al, 1989;Laughlin et al, 1993). We had reported that VPA also stimulated HIV replication (Simon et al, 1994).…”
