Figure 1 Sequencing results of mitochondrial 12S rRNA in gastric cancer.
A: Normal 12S rRNA (652G); B: 12S rRNA 652G insertion ; C: Normal 12S rRNA (716T, 728C); D: 12S rRNA 716 T-G transversion , 728 C-T transition.
Figure 2 Analytic results obtained by denaturing high performance liquid chromatography.
A: np 652G insertion, heteroplasmic mutation; B: np 716 T-G transversion, heteroplasmic mutation.
Figure 3 Mutant property of 12S rRNA 716T-G shown in AS-PCR analysis.
A: gastric cancerous cells; B: dysplasia cells. Lanes 1-5: mutant type 12S rRNA; lane 6: pGEM-7ZF marker (HuaMei) and 100 bp Ladder marker (TaKaRa) respectively; lanes 7-11: wild type 12S rRNA; lanes 12, 13: mix type 12S rRNA of gastric cancerous cells and dysplasia cells respectively.
Figure 4 RNA secondary structure prediction of mutant type of 12S rRNA.
dG: free enegy of RNA secondary structure (kcal/mol); ins: insertion. Arrowhead indicates local RNA structural change.
