| Outline of Final Research Achievements |
The axon guidance molecule-receptor system works not only in neural network formation, and but also in cancer cell proliferation and apoptosis. Draxin and Netrin1 share their receipt, DCC and Neogenin. This study was done to elucidate the significance of the guidance molecule-receptor system in lung cancer cell proliferation and survival. Western blotting and immunohistochemical studies revealed that small cell lung cancer and non-small cell lung cancer express these molecules. Though gene knockdown and over-expression studies using small cell lung cancer cell lines, using non-small cell lung cancer cell lines, we demonstrated that the system works in lung cancer cell proliferation and survival. And, it is suggested that Draxin could interact directly with Netrin1 in cancer cell proliferation.
