WebJul 24, 2024 · Schematic mechanisms of primary resistance to FLT3 inhibitors. (1) Wild-type FLT3s are a little sensitive to FLT3 inhibitors and allow downstream signaling by … WebIt is one of the 3 most common mutations in AML and relates to higher leukocyte counts especially in the presence of FLT3-ITD fusion oncogene [35]. NPM1 mutations may occur in de novo AML cases or can be co-expressed with RUNX1-RUNX1T1 transcripts [37,38]. Similar results of NPM1 gene mutations on exon 12 were found in this study.
WebNov 1, 2024 · The ability of gilteritinib to inhibit FLT3 and AXL could be a leverage to eradicate FLT3-mutated AML clones but also FLT3 wild-type clones since AXL is also implicated in resistance to conventionnal chemotherapy. These data strongly support current clinical trials associating chemotherapy and gilteritinib. WebNov 19, 2024 · Understanding the mechanism of resistance to FLT3-targeted therapy is crucial to eradicate MRD-causing clones. The exact mechanism by which MRD clones survive and eventually lead to resistance is not completely clear. There are several factors that can influence response to therapy, which can be receptor and nonreceptor related. ...
WebNov 5, 2024 · As expected, the F691L mutation provided broad resistance to most FLT3i (Fig. 2). To validate this mechanism of resistance in patients, we identified a relapsed FLT3-ITD patient who was treated with GILT monotherapy for 5 months, followed by GILT + HMA for 4 cycles, and then GILT + VEN for resistant proliferative disease. WebAug 23, 2024 · FLT3 inhibition reshapes the nascent proteome. To identify pathways responsible for cell-autonomous resistance to FLT3i in AML, we used a recently developed unbiased proteomic method—multiplexed ...
