| Outline of Final Research Achievements |
Currently, there are anti-cancer drugs available for gastric cancer (GC) treatment, while various side effects are intractable limitations for some patients. Here, to identify the anti-cancer drug candidate(s) for GC with no side effects, we performed an imaging mass spectrometry screening using a panel of non-neoplastic and neoplastic gastric tissue. Two species of phosphatidylcholine (PC), PC-34:2 and PC-36:4, were highly downregulated in GC. PC-34:2 and PC-36:4 suppressed the transformation of NIH3T3 cells driven by K-rasV12 and growth of 5 cell lines, while the growth of non-transformed NIH3T3 was not affected by PC-34:2. overexpression of LPCAT3 leads to growth suppression of MKN-28 cells. Considering that PCs have no toxic effect for human, these data indicate the usefulness of identified PC as potential anti-cancer drugs of GC.
