Effect of Tid1 knockdown on mtDNA copy number and mitochondrial gene expression of gastric cancer cells. (A) The effect of Tid1 knockdown on mtDNA copy number was evaluated by real-time PCR. (B–D) The effect of Tid1 knockdown on mitochondrial gene expression was evaluated by reverse transcription (RT)-real-time PCR in the (B) AGS, (C) NUGC-3, and (D) TSGH 9201 gastric cancer cells. The efficiency of Tid1 knockdown was confirmed by Western blot or RT-real-time PCR. Data are shown as the mean ± SD of at least three independent experiments. *, p < 0.05, compared with the siRNA for scramble (siScr) control group.
