Proteomic profiling showed that NAMPT inhibition with KPT-9274 induced adaptive upregulation of BCL2, an anti-apoptotic protein, highlighting a survival mechanism...Additionally, NAMPT inhibition reduced PARP activity and impaired DNA repair pathways, sensitizing AML cells to cytarabine and hypomethylating agents. Together, these results demonstrate that NAMPT inhibition both potentiates venetoclax activity and enhances the cytotoxic effects of standard chemotherapies by targeting metabolic and DNA repair vulnerabilities. These findings provide strong preclinical support for evaluating NAMPT and BCL2 dual inhibition strategies in future AML clinical trials.
For relapsed and refractory APL, relevant drug resistance gene monitoring should be carried out. Some relapsed and refractory APL patients who do not respond to conventional treatment are at risk of death. We report a successful case, the regimen of VEN targeted therapy combined with chemotherapy still holds promise for the treatment of future relapsed/refractory APL.

Leukemic stem cells (LSCs) in acute myeloid leukemia (AML) depend on oxidative phosphorylation (OXPHOS) sustained by fatty acid oxidation (FAO) and mitochondrial fusion (mitofusion). In vivo, miRisten potentiated the VEN/azacitidine (AZA) regimen, an FDA-approved therapy for older or unfit AML patients, significantly prolonging survival in patient-derived xenograft models. VEN/miRisten combination also reduced LSC burden and restored VEN sensitivity, establishing miR-126 inhibition as a transformative therapeutic strategy in AML.
The senolytic Navitoclax targeted only a subset of senescent cells. Thus, the diversity of senescent cells driven by epigenetic changes can generate divergent outcomes. UHRF1 overexpression in zebrafish hepatocytes induces DNA damage leading to Atm-tp53-dependent senescence with UHRF1 levels dictating whether hepatocytes remain senescent, escape, or undergo senolytic elimination.
