Bcl-2 homology domain 3 (BH3) mimetics, such as venetoclax (ABT-199), which targets BCL2, have shown promising activity in AML. Additionally, MIK665 showed significant activity against a subset of paediatric AML patient-derived xenografts (PDXs) in both ex vivo and in vivo experiments, with minimal impact on cardiac tissue pathophysiology. These findings strongly support the clinical advancement of MIK665 for paediatric AML treatment in a precision medicine approach.
Therefore, this platform is particularly suited for the treatment of FLT3-ITD AML while potentially applicable to other AML subtypes with high CD71 expression. By enabling specific intracellular accumulation of HHT and multitarget inhibition of FLT3 signaling pathways, this system achieves enhanced anti-AML efficacy both in vitro and in vivo, offering strong potential for future clinical translation.
The resulting nanoparticles were investigated in a refractory AML mouse model (AML1-ETO & C-KITD816V) with a high level of CXCR4 and in the t(8; 21)-positive AML cell line Kasumi-1. It was shown that E5-LNP@siAE effectively achieved RNAi of AML1-ETO and antagonism of CXCR4, thereby synergistically inducing effective multi-lineage differentiation, leading to significantly enhanced differentiation-post apoptotic responses of AML cells to homoharringtonine and remarkably prolonged survival in refractory AML mice.
Sabutoclax treatment was associated with both decreased protein expression and reduced nuclear translocation of NFATc1. Future studies could focus on comprehensive evaluation of its pharmacokinetic properties, systemic toxicity, and therapeutic efficacy in more clinically relevant metastatic models to establish its potential application in breast cancer-induced osteolytic bone destruction.

We previously conducted a prospective clinical trial on R/R AML with chemotherapy regimen BHA (bortezomib, homoharringtonine and cytarabine), which demonstrated promising efficacy in patients with FLT3-mutated R/R AML. Notably, this degradation effect was partially reversed by chloroquine. These findings demonstrate that bortezomib and homoharringtonine have synergistic effects and lead to degradation of FLT3-ITD oncoprotein, potentially contributing to a higher complete remission rate in FLT3-ITD R/R AML.

We report a case of a 42-year-old patient with EVI1-positive AML harboring the MLL-AF6 fusion gene, who failed to achieve remission after undergoing standard "IA" induction therapy and was then treated with VAH (venetoclax, azacitidine, and homoharringtonine) consolidation chemotherapy. This case suggests that the combination of ATRA with the VAH regimen may demonstrate promising efficacy and an acceptable safety profile in patients with EVI1-positive AML who are refractory to conventional chemotherapy. However, further clinical studies are required to confirm its wider applicability.
These findings identify a novel oncogenic role for SPOP loss in promoting breast cancer progression via GLI3-dependent SHH signaling. Furthermore, gossypol is highlighted as a potential targeted therapeutic agent for breast cancers characterized by SPOP deficiency.

Furthermore, we identify a synergistic antitumor effect between KPT-330 and translation inhibitors, including everolimus and homoharringtonine. Notably, the disruptive impact of KPT-330 on CRC homeostasis extends to other cancer cell lineages, underscoring its broad mechanistic relevance. Collectively, our findings elucidate a novel mechanism through which KPT-330 destabilizes CRC via translational dysregulation and highlight its potential therapeutic utility in combination regimens for DDLPS.
