Flt3 resistance mechanism
WebDec 10, 2024 · Secondary resistance mechanisms against FLT3 inhibitors were classified into on-target and off-target mechanisms, in which leukemia cells become dependent on other signaling pathways. 7.1 On-target resistance. In on-target resistance, leukemia cells retain dependency on FLT3 signals but show resistance to FLT3 inhibitors by acquiring … WebSep 14, 2024 · The mechanisms underlying FLT3 inhibitor tolerance can be roughly divided into primary resistance and secondary resistance. Primary resistance is related to abnormalities in signaling factors, such as FL, CXCL12, and FGF2, and secondary resistance mainly involves on-target mutations and off-target aberrations.
