Outcomes appear to be influenced by an interplay of disease context, clonal architecture, and therapeutic strategy rather than individual mutations alone, underscoring the need for integrated molecular profiling and prospective studies to guide management. This study highlights that MS with MR mutations may follow different cellular pathways to evolution.

Novel menin inhibitors, including revumenib, bleximenib, ziftomenib, and enzomenib, are currently under clinical evaluation, and selected updated clinical results were presented at the 2025 American Society of Hematology (ASH) Annual Meeting. This brief review summarizes the key findings and discusses the emerging clinical questions regarding combination strategies, treatment sequencing, and molecularly defined use of menin inhibitors.

Mutation-specific NPM1 IHC is a valuable tool for a rapid assessment of residual morphologic and molecular disease in mid- and postinduction NPM1mut AML.

Our results provided new insights into the mechanisms of intestinal cancer progresses by paracrine IR-PD-L1 signaling, which is aided by the deregulation of oxidative stress and macrophage communication brought on by smoking carcinogen-induced the metabolic syndrome.

The approach enabled early relapse prediction in selected patients and improved molecular follow-up, even for rare NPM1 mutations not covered by standard qPCR panels. It simplifies laboratory routine and improves MRD assessment, according to current ELN guidelines and the growing need for personalized molecular monitoring in AML.

Key findings were validated by CETSA, isothermal dose-response fingerprinting, co-immunoprecipitation, and ubiquitination assays. These results demonstrate that shogaol exerts dual cytotoxic effects through the PLK1/NPM1 axis, presenting a potential natural therapeutic approach for Ewing sarcoma.

Notably, we observed that knockdown of SCD1 in vitro or its pharmacological inhibition in vivo enhances cancer cell sensitivity to HDAC inhibitors. Our findings underscore the role of SCD1 in reshaping the cellular acetylome and suggest that targeting SCD1 could sensitize cancer cells to HDAC inhibitors, highlighting a promising therapeutic strategy.

As an exploratory analysis, subtype-specific therapeutic vulnerabilities were revealed: Subtype A displays predicted sensitivity to immune checkpoint inhibitors (anti-PD-1) and tipifarnib, whereas Subtype B responds better to cytarabine/doxorubicin. Crucially, experimental validation confirmed significant upregulation of key model genes (HIP1, SQLE, VNN1) in AML patient samples and cell lines (P < 0.05), reinforcing the model's biological relevance. These findings establish PCD dysregulation as a central axis of AML heterogeneity, providing a framework for precision risk stratification and hypothesis-generating immunophenotype-guided therapy.

Clinical activity observed with menin inhibitors provides translational validation of this dependency and establishes menin inhibition as a differentiation-based therapeutic strategy. In this review, we examine the molecular basis of menin-dependent transcriptional regulation in AML and its implications for therapeutic targeting with menin inhibitors and resistance to therapy.
