| Outline of Final Research Achievements |
Previously, we established mast cell lines from mouse spleen and induced their autonomous proliferation by reducing cytokines that are required for normal mast cell growth. Furthermore, the mast cell line have characteristic features of mastocytoma cells. Thus, this experimental system help us to understand the mechanism of development of mast cell cancer.
In this study, we found that Kit autophosphorylation and activation of Erk and of Akt occur in the early stage of cancerization, whereas STAT5 activation is found only in the late phase. At present, analyses of molecular mechanism of the stage-specific activation of Kit,Erk, Akt, and STAT5 are under way.
