Trex1 knockdown increases cytosolic retrotransposon DNA levels. (A) Cytosolic DNA was isolated from NR9456 cells treated with the siRNAs indicated. The retrotransposon DNA copy number was measured by qPCR and normalized to that of the mitochondrial gene for cytochrome b (mtCytb). I, II, and III in parentheses indicate class I, II, and III retroviruses, respectively. The values shown are the mean ± the standard error of the mean of three experiments. *, P < 0.05; **, P < 0.005; ***, P < 0.0005 (two-tailed t test). siCont, control siRNA.
