Rewiring NADH Metabolism Through NQO1‐Mediated Redox Cycling for Targeted Follicular Lymphoma Therapy

Advanced Science, EarlyView.
ABSTRACT Follicular lymphoma (FL) remains an incurable B‐cell malignancy with high relapse rates, and conventional therapies are often limited by significant toxicity, highlighting the need for novel treatments. We identified that FL exhibits markedly low expression of NAD(P)H: quinone oxidoreductase 1 (NQO1), a key enzyme required for activating ...

Pathogen‐Centric Activation of an Azoreductase‐Responsive Antibody‐Antibiotic Conjugate for the Targeted Eradication of MRSA

Advanced Science, EarlyView.
A pathogen‐centric antibody‐antibiotic conjugate (AZO‐AAC) releases antibiotics via bacterial azoreductase, independent of host‐lysosomal function. This mechanism achieves nanomolar eradication of both planktonic and intracellular methicillin‐resistant Staphylococcus aureus (MRSA).

A Catalytic Osmium Redox Couple Collapses Cancer Redox Balance

Advanced Science, EarlyView.
A stable Os(III)/Os(IV) redox couple is developed to disrupt the tumor cell redox balance by concurrently catalyzing ROS generation and GSH depletion. Osmium‐treated cells exhibit multiple cell death pathways, including apoptosis, ferroptosis, and immunogenic cell death.

Stage‐Specific H3K14 and H3K23 Succinylation Orchestrates Insect Metamorphosis and Oogenesis

Advanced Science, EarlyView.
Stage‐specific succinylation of histone H3 at lysine 14 and 23 differentially controls insect metamorphosis and oogenesis through distinct GPCR‐PKC signaling cascades, revealing an evolutionarily conserved epigenetic mechanism that coordinates key life‐history traits.

PIEZO1 is Required for Acute Myeloid Leukemia Progression and Leukemia Stem Cell Maintenance via HIF1A‐SLC7A11 Axis‐Mediated Ferroptosis Defense

Advanced Science, EarlyView.
This study identifies the mechanosensor PIEZO1 as a key factor in promoting acute myeloid leukemia progression and uncovers a ferroptosis defense system mediated by PIEZO1‐HIF1A‐SLC7A11 axis that is essential for leukemia stem cell maintenance. This ferroptotic defense system may represent a unique vulnerability for leukemia stem cells, providing a ...
