Outline of Final Research Achievements |
We have analyzed cell signaling generated by the interaction between glycosphingolipids expressed on cancer cells and neighboring membrane molecules expressed in the vicinity of them, and aimed to apply the results in the construction of cancer therapeutic strategies targeting membrane microdomain leading to obtain fundamental information by clarifying the implication of the signals in the regulation of cell phenotypes. In order to do so, we used Enzyme-mediated activation of radical sources (EMARS)/mass spectrometry, to identify the interacting molecules with cancer-associated glycolipids. In melanomas, we identified neogenin as a GD3-associated molecule, in human gliomas, EphA2 as a GD2 associated molecule, and in small cell lung cancers, ESCT2 was identified as a GD2-associated molecule. Furthermore, PDGF receptor alpha was also identified as GD3-associated molecule in murine glioma cells. Then, individual molecular functions of these membrane molecules have been investigated.
