Outline of Final Research Achievements |
Our previous study has indicated that SP-D suppresses EGF signaling by interfering with the ligand-binding to EGFR. SP-D directly binds to the N-glycans of EGFR by lectin activity. In this study, we indicated that SP-A also downregulated EGF signaling by inhibiting ligand-binding to EGFR. In addition, we found that SP-A directly bound to EGFR, but not via N-glycans. Elucidating the antitumor effects of SP-A and SP-D may provide important clues for establishing new therapeutic strategies for lung cancer.
