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

Figure 7 RT-PCR for expression of mtDNA ATPase subunits 6 and 8 mRNA in rates with ethanol-induced acute gastric mucosa injury. M: 100 bp DNA ladder was a RT-PCR product of β-actin mRNA (upper row, 300 bp); lanes 1-4: RT-PCR products of mtDNA ATPase subunit 6 mRNA after treatment with normal sodium, 40% (W/W) ethanol, 70% (W/W) ethanol, and 100% (W/W) ethanol, respectively; lanes 5-8: RT-PCR products of mtDNA ATPase subunit 8 mRNA after treatment with normal sodium, 40% (W/W) ethanol, 70% (W/W) ethanol, and 100% (W/W) ethanol, respectively.
