Figure 6. Schematic of Proposed Mechanism for p22phox-mediated H2O2 signalling in FLT3-ITD AML cell lines.
p22phox is required for the production of H2O2 in AML cell lines at the Endoplasmic reticulum. Inhibition of FLT3 signalling in these cells leads to degradation of p22phox by the proteasome, which requires active GSK3-β. Removal of p22phox from this system halts STAT5 signalling to Pim-1.
