XPO1 inhibitor KPT-330 disrupts the core transcriptional regulatory circuitry of dedifferentiated liposarcoma by modulating the translation process. (PubMed, Oncogene)
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.

Quizartinib and omacetaxine mepesuccinate combination therapy in FLT3-ITD AML: a phase II trial. (PubMed, Nat Commun)
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.

Observation of the Therapeutic Effect of Venetoclax Combined with HEA Regimen on Acute Myeloid Leukemia Patients with KMT2A Gene Rearrangement (PubMed, Zhongguo Shi Yan Xue Ye Xue Za Zhi)
The VHEA regimen can significantly improve the CR rate of AML patients with KMT2A gene rearrangement, with good safety. It may be a better choice for induction remission chemotherapy in newly diagnosed and relapsed/refractory AML patients with KMT2A gene rearrangement.

Efficacy and safety of venetoclax-cytarabine-homoharringtonine-based cytoreductive therapy before allogeneic hematopoietic stem cell transplantation in refractory/relapsed acute myeloid leukemia with RUNX1::RUNX1T1: a retrospective study (PubMed, Zhonghua Xue Ye Xue Za Zhi)
All patients remained disease-free, with no events of measurable residual disease (MRD) positivity by flow cytometry or molecular analysis documented. These findings preliminarily confirm that venetoclax, cytarabine, and homoharringtonine-based cytoreductive therapy is a safe and effective bridging therapy for allo-HSCT in patients with refractory/relapsed AML and RUNX1::RUNX1T1 fusion gene.

Homoharringtonine inhibits growth and migration in non-small cell lung cancer via PDIA4-mediated modulation of autophagy and EMT. (PubMed, Arch Pharm Res)
Additionally, HHT inhibits NSCLC migration by modulating epithelial-mesenchymal transition (EMT) signaling. These findings highlight PDIA4 as a critical mediator of HHT efficacy against NSCLC, provide novel insights into PDIA4-associated therapy, and support the translational potential of HHT in NSCLC treatment.

Homoharringtonine and Gilteritinib Synergistically Induce Apoptosis and Suppress Viability in FLT3-ITD-Positive AML Cells. (PubMed, Biomedicines)
The combination enhanced the p53 expression. Our findings elucidate the mechanism underlying this synergistic interaction and underscore the potential of p53 status as a predictive biomarker for identifying patients most likely to benefit from HHT and gilteritinib combination therapy.
