Purification and characterization of oat polyamine oxidase

, 1989
Polyamine oxidase from oat shoots was purified to homogeneity by the criteria of polyacrylamide gel electrophoresis in native and denaturing conditions. The purified yellow enzyme had an Amax at 276, 370 and 452 nm.

The Efferocytosis‐Driven Macrophage Polarization: A Concerto in the Tumor Immunosuppressive Microenvironment

MedComm, Volume 7, Issue 11, November 2026.
Efferocytosis is a key process for macrophages to clear apoptotic cells, which undergoes the “ Find Me” chemotaxis signal stage, the “eat me” phagocytosis recognition stage and the “digest me” digestion stage in turn. During the aforementioned three stages, various signaling molecules released by apoptotic cells can promote the phenotypic polarization ...

Targeted and Biosafe Delivery of Spermidine to Ameliorate Foreign Body Responses After Synthetic Vascular Graft Implantation In Vivo

Small Structures, Volume 7, Issue 11, November 2026.
Platelet membrane fragment‐modified lipid nanoparticles (PLNP‐SPD) safely deliver spermidine, reduce its cytotoxicity, selectively bind inflamed macrophages, and suppress their inflammatory activation. After adventitial delivery around vascular grafts, PLNP‐SPD reduces foreign body reactions and inflammation, promotes implanted vessel regeneration in ...

GABAergic Network Dysregulation in Alcohol Use Disorder: Receptor–Transporter Interactions Driving the Transition From Goal‐Directed to Compulsive Behaviour

Addiction Biology, Volume 31, Issue 11, November 2026.
Astrocytic GAT3 regulates ambient GABA levels in the globus pallidus externus (GPe). Reduced GAT3 function enhances extrasynaptic GABAergic signalling and disrupts subthalamic nucleus (STN) regulation and cortical signal fidelity.ABSTRACTAlcohol use disorder (AUD) is characterized by a shift from controlled, goal‐directed drinking to compulsive ...

The Sweetpotato Black Rot Pathogen Ceratocystis fimbriata

Molecular Plant Pathology, Volume 27, Issue 11, November 2026.
We review current knowledge of the soilborne Ceratocystis fimbriata pathogen's biology, epidemiology, virulence and management, and identify priorities for future research. ABSTRACT Black rot, caused by the soilborne fungus Ceratocystis fimbriata, is a major postharvest disease of sweetpotato (Ipomoea batatas) worldwide.

Inhibition of chickpea seedling copper amine oxidases by tetraethylenepentamine [PDF]

Copper amine oxidases are important enzymes, which contribute to the regulation of monoand polyamine levels. Each monomer contains one Cu(II) ion and 2,4,5-trihydroxyphenylalanine (TPQ) as cofactors.

Chromatin Packing Domain Engineering Through the Manipulation of Nuclear Cationic States

Advanced Science, Volume 13, Issue 58, 19 October 2026.
Manipulation of intranuclear divalent cation concentrations rapidly and reversibly remodels chromatin packing domains in living cells. Magnesium depletion disrupts domain compaction, heterochromatin organization, and transcriptional regulation, whereas magnesium loading promotes more compact and stable domains.
