Cooperative Regulation of Mcl-1 by Janus Kinase/STAT and Phosphatidylinositol 3-Kinase Contribute to Granulocyte-Macrophage Colony-Stimulating Factor-Delayed Apoptosis in Human Neutrophils

Polymorphonuclear neutrophils (PMN) are phagocytic cells constitutively programmed for apoptotic cell death. Exposure to GM-CSF delays apoptosis as measured by annexin-V staining and cell morphological change. We found that STAT5B, STAT1, and STAT3 DNA-binding activity was induced by GM-CSF. We also...
