Research Abstract |
The complete genome sequences of four Helicobacter pylori strains isolated from Japan were determined. A phylogenetic tree of concatenated well-defined core genes supported divergence of the East Asian lineage from the European lineage ancestor, and then from the Amerind lineage ancestor. Phylogenetic profiling revealed a large difference in the repertoire of outer membrane proteins. The results define H. pylori East Asian lineages and provide essential information for understanding their pathogenesis. We investigated metabolome analysis using liquid chromatography-mass spectrometry, gas chromatography-mass spectrometry. Lactic acid was upregulated in H. pylori infected AGS(gastric cancer cell line) cells and serum of gastric cancer patients. In contrast, malic acid was downregulated in H. pylori infected AGS cells and serum of gastric cancer patients.
