MicroRNAs (miRNAs) regulate gene expression and may contribute to HIV-1 infection. In this study, our goal was to investigate the mechanisms by which miR-34a influenced Tat-induced HIV-1 transactivation through the SIRT1/NFκB pathway. We showed that Tat induced up-regulation of miR-34a expression in TZM-bl cells. MiR-34a significantly inhibited SIRT1 expression. Overexpression of miR-34a increased...
