Figure 2. Chemical inhibition of SGK1 abrogates neutrophil survival through an increase in apoptosis.
Human neutrophils were treated as indicated for 8 hours and percentage apoptosis scored by cytospin analysis. a) GSK650394 causes an increase in apoptosis rates and the 10 μM concentration significantly inhibits GM-CSF induced neutrophil survival (t-test, *p<0.05, n=5). b) Caspase inhibition prevents all neutrophil death (t-test, *p0.05, n=4). c) Neutrophil survival factors lower apoptosis rates at 8 hours, GSK650394 treatment abrogates survival caused by GM-CSF and DMOG but not that by LPS and ATPγs (*p<0.05, n=3).
