Oxidative stress disturbs energy metabolism of mitochondria in ethanol-induced gastric mucosa injury

Figure 9 RT-PCR for expression of mtDNA ATPase subunit 8 mRNA in rats with ethanol-induced chronic gastric mucosa injury. M: 100 bp DNA ladder of RT-PCR products of β-actin mRNA (upper row, 300 bp); lanes 1-9: RT-PCR products of mtDNA ATPase subunit 8 mRNA 3 wk after treatment with normal sodium, 25% (W/W) ethanol, and 45% (W/W) ethanol, respectively; 6 wk after treatment with normal sodium, 25% (W/W) ethanol, and 45% (W/W) ethanol, respectively; 9 wk after treatment with normal sodium, 25% (W/W) ethanol, and 45% (W/W) ethanol, respectively.
