The cell cycle protein Cks1 is deregulated in several malignancies and upregulation is associated with poor prognoses. This study examines the suspected oncogenic role of Cks1 during pathogenesis of hematopoietic malignancies. Additionally, p27 independent functions of Cks1 were analyzed during tumorigenesis. By using different transplantation models it was shown that Cks1 overexpression alone is not oncogenic, but Cks1 contributes to tumor proliferation by suppressing p27. Evaluation of a cooncogenic role of Cks1 with the constitutively activated gp130 receptor L-gp130 showed no cooperating oncogenic activity. Furthermore, high titer L-gp130 transduction led to the establishment of a new AML model.
