English abstract
PTEN and SHP1 are tumor suppressor genes involved in the regulation of cell cycle control and apoptosis. We have investigated the protein expression of PTEN and SHP 1, by immunohistochemistry in micro tissue arrays from bone marrow samples in children, diagnosed with acute lymphoblastic leukaemia and non-malignant controls. PTEN was over expressed in ALL samples, while SHP1 showed a low expression. PTEN showed a significant difference in expression compared to non-malignant controls. The role of PTEN and SHP1 are not well investigated in pediatric leukemias and could in future play a role as prognostic factors.
