Prophage Activation Triggers Extracellular Synthesis of DNA in Bacterial Biofilms via Rolling Circle Replication

Angewandte Chemie, Volume 138, Issue 41, 5 October 2026.
Shewanella oneidensis and Bacillus subtilis, both harboring prophages, reveal a novel biosynthetic route to scalable and programmable DNA superstructures in flower‐ and wire‐like shapes, respectively. Activation of prophages is achieved via 3‐hour starvation and monitored using reporter strains.

Cross‐Scale Engineering of Single‐Atom Catalysts from Local Planar Coordination to Spatial Architectures

Small, EarlyView.
This Review presents a cross‐scale framework for single‐atom catalysts, spanning in‐plane and out‐of‐plane coordination; primary coordination, secondary‐sphere interactions, through‐space microenvironments and support interfaces; individual sites and macroscopic architectures; and static design and directed dynamic reconstruction.

Hemin regulates platelet clearance in hemolytic disease by binding to GPIbα

Platelets
Hemolysis is associated with thrombosis and vascular dysfunction, which are the pathological components of many diseases. Hemolytic products, including hemoglobin and hemin, activate platelets (PLT).

Improvement of a Hemin Standard by Recrystallization

Experimental Biology and Medicine, 1952
Summary1. The purity of crude hemin preparations used, as determined by their iron content, was improved by recrystallization. 2. Crude hemin preparations in borate buffer showed variable extinction coefficients at any wavelength selected along the flat portions of the absorption spectra.

A Serum‐Resistant Plasma Membrane Probe for Real‐Time Visualization of Pathogen‐Induced Epithelial Barrier Dysfunction

Small, EarlyView.
PM580 selectively activates at the plasma membrane while remaining minimally responsive to serum albumin, enabling serum‐compatible, surface‐confined imaging for 24 h, unlike conventional probes that rapidly internalize and lose membrane contrast.

Improving the anthocyanin accumulation of hypocotyls in radish sprouts by hemin-induced NO

BMC Plant Biology, 2022
Background The health benefits of anthocyanins impel researchers and food producers to explorer new methods to increase anthocyanin contents in plant foods. Our previous studies revealed a positive role of nitric oxide (NO) in anthocyanin accumulation in

Electrochemical aptasensors for ultrasensitive multiplexed detection: Towards a new era of precision diagnostics and environmental monitoring

VIEW, EarlyView.
Electrochemical aptasensors are emerging as powerful platforms for precision diagnostics and environmental monitoring, owing to their high selectivity, programmability and compatibility with miniaturised systems. However, their broader application is constrained by limited signal intensity and challenges in reliable multiplexed detection.

Beyond monofunctionality: structural perspectives on phenol oxidase side activity in a catalase

Acta Crystallographica Section D, EarlyView.
Structural and biochemical characterization of the extracellular fungal catalase ClCPO uncovers an unexpected phenol oxidase promiscuity. Crystal structures, substrate docking and electron‐transfer pathway analysis identify ligand‐binding regions and support a working mechanistic model for catalase‐associated phenol oxidase activity.Catalases are ...

Targeting the NR3C1‐ACSL4 Axis Triggers Ferroptosis to Overcome Radioresistance in Prostate Cancer

Cancer Science, EarlyView.
The glucocorticoid receptor NR3C1 drives prostate cancer radioresistance by upregulating ACSL4. High ACSL4 levels create a lipid metabolic vulnerability. The clinical agent DHA synergizes with ACSL4 to induce lipid peroxidation and ferroptosis, effectively overcoming radioresistance.
