ABSTRACT
Objective To elucidates the regulation of Notch1 activity by Rab5 which controls endosome fusion.Methods Rab5 expression of BxPC3 cells were inhibited by siRNA interference,the changes of Notch ICD protein were measured by Western blot.We use Wortmannin and LY294002 which inhibit the acticity of Phosphatidylinositol(PI) 3-kinases to investigate Notch ICD protein level.Results After inhibiting Rab5 expression or the activity of Phosphatidylinositol(PI) 3-kinases,Notch ICD protein level and the growth of BxPC3 cells decreased.Conclusion In BxPC3 cells,Rab5 and Phosphatidylinositol(PI) 3-kinases are important to regulate Notch1 activity and the activation of Notch is dependent on endocytosis.
