These subnetworks included hub genes such as IFIT1, PSMB9, and HLA-B, which are known to be associated with immune evasion and drug resistance in acute myeloid leukemia. Our findings demonstrate that the proposed method enables statistically reliable and biologically interpretable identification of phenotype-specific gene regulatory mechanisms, providing insights into potential therapeutic targets.

In a Ba/F3 FLT3-ITD-F691L mouse model, nintedanib demonstrated superior anti-leukemic efficacy compared with gilteritinib and quizartinib. Furthermore, nintedanib potently inhibited primary AML blasts harboring FLT3-ITD while normal bone marrow remained intact. These findings identify nintedanib as a promising FLT3 inhibitor and support its further therapeutic investigation in FLT3-ITD-positive AML.

Functionally, MV4-11QR cells showed broad cross-resistance to clinically relevant agents, including midostaurin, venetoclax, and cytarabine. Importantly, pharmacological targeting of mutant p53 with eprenetapopt or MAPK signaling with trametinib restored sensitivity to quizartinib, inducing synergistic or additive cytotoxic effects and increased apoptosis. Together, these findings define a multilayered resistance program involving genetic, signaling, and metabolic adaptations and support rational combination strategies to overcome FLT3 inhibitor resistance in AML.

First-generation inhibitors, such as midostaurin, provided the foundation for targeted therapy, while recently developed agents such as gilteritinib and quizartinib have shown more selectivity and demonstrated superior clinical efficiency and improved tolerability. This review discusses the significance of FLT-3 mutations, the evolution of targeted therapies, current treatment guidelines, and ongoing challenges such as resistance and high relapse rates. We also discuss the emerging combinations of therapies and novel agents currently in clinical trials that aim to overcome resistance and improve long-term outcomes for patients with FLT-3-mutated AML.

PLD1-inhibitor remodeled phospholipid metabolism, induced ferroptosis and restored QUIZOM response in LSC. Our findings provided the therapeutic and resistant mechanisms of QUIZOM and paved the way for targeted interventions in this AML subtype.

Here, we detail the current targeted therapies available for AML: specifically, those targeting the BCL2 family (venetoclax), FLT3 (midostaurin, gilteritinib, quizartinib), IDH1/2 (enasidenib, ivosidenib), and MENIN (revumenib, ziftomenib). In addition, we outline potential mechanisms of resistance against these therapies, as well as efforts being taken to prevent or bypass them.

In patient-derived xenograft models, co-treatment with FLT3i (quizartinib) and CD276-targeting agents led to 72.9%-80.4% tumor burden reduction and enhanced CD8+ T cell function, outperforming quizartinib monotherapy. These findings define a scaffolded PKCι-pS727-STAT1 signaling axis that promotes immune evasion in FLT3-ITD AML, supporting combined FLT3 and CD276 targeting as a promising translational strategy in this aggressive leukemia subtype.
