Outline of Final Research Achievements |
By the screening of phosphotyrosine-containing proteins associated with ALK in neuroblastoma cells, we identified SHP2 as one of the binding partners of ALK. Immunoprecipitation study revealed binding of SHP2 with ALK by ALK activity-dependent manner, and knockdown of ALK or inhibition of kinase activity of ALK by ALK inhibitors suppressed phosphorylation of SHP2 at Tyr540 and Tyr580 in NB-39-nu neuroblastoma cells which have ALK addiction. In addition, knockdown of ALK-binding docking protein ShcC resulted in decrease of ALK-SHP2 interaction. On the other hands, treatment of SHP2 inhibitor PHPS1 or knockdown of SHP2 resulted in down-regulation of ERK1/2 activation, proliferation and migration of NB-39-nu cell. However, phosphorylation of ALK was up-regulated by inhibition or knockdown of SHP2. From these results, very complicated interplay between ALK and SHP2 during the regulation of oncogenesis of the neuroblastoma cells is suggested.
