It was reported that somatic mutations in the mitochondrial DNA (mtDNA) are associated with high-frequency microsatellite instability (MSI-H) of the nuclear in gastric cancers. However, no correlation between mtDNA mutations and nuclear MSI-H was found in colorectal, breast, and renal cancers. Therefore, the association between mtDNA mutations and nuclear MSI-H in gastric cancers is controversial. We examined mtDNA mutations and nuclear MSI in a large panel of gastric cancers. One-hundred and five gastric cancers were selected. Mutations in the mononucleotide repeat (D310) of mtDNA and nuclear MSI at 5 microsatellite loci were examined by microsatellite assay. Somatic mutations in the mtDNA and nuclear MSI-H were detected in 16 (15%) and 14 (13%) of the gastric cancers, respectively. mtDNA mutations were detected in 2 of the 14 (14%) and 14 of the 91 (15%) tumors with and without nuclear MSI-H, respectively. There was no significant difference between them. These results suggest that somatic mutations in the mtDNA and nuclear MSI-H play important roles in gastric carcinogenesis, and that mtDNA mutations may not be associated with nuclear MSI-H in gastric cancers.
