Loss of SHIP and CIS Recruitment to the Granulocyte Colony-Stimulating Factor Receptor Contribute to Hyperproliferative Responses in Severe Congenital Neutropenia/Acute Myelogenous Leukemia

Abstract excerpt

Mutations in the G-CSF receptor (G-CSFR) in patients with severe congenital neutropenia (SCN) are postulated to contribute to transformation to acute myelogenous leukemia (AML). These mutations result in defective receptor internalization and sustained cellular activation, suggesting a loss of negative signaling by the G-CSFR. In this paper we investigated the roles of SHIP and cytokine-inducible Src homology 2...
