Is Root Catalase a Bifunctional Catalase-Peroxidase? [PDF]
Antioxidants, 2017 Plant catalases exhibit spatial and temporal distribution of their activity. Moreover, except from the typical monofunctional catalase, a bifunctional catalase-peroxidase has been reported. The aim of this study was to investigate whether the leaf and root catalases from six different plant species (Lactuca sativa, Cichorium endivia, Apium graveolens ...

Peroxisomal Proteostasis Involves a Lon Family Protein That Functions as Protease and Chaperone [PDF]
, 2012 Proteins are subject to continuous quality control for optimal proteostasis. The knowledge of peroxisome quality control systems is still in its infancy. Here we show that peroxisomes contain a member of the Lon family of proteases (Pln).

The quest to quantify selective and synergistic effects of plasma for cancer treatment: Insights from mathematical modeling [PDF]
Int. J. Mol. Sci. 22(9), 5033 (2021), 2021 Cold atmospheric plasma (CAP) and plasma-treated liquids (PTLs) have recently become a promising option for cancer treatment, but the underlying mechanisms of the anti-cancer effect are still to a large extent unknown. Although hydrogen peroxide has been recognized as the major anti-cancer agent of PTL and may enable selectivity in a certain ...

Cerium (III) and (IV) containing mesoporous glasses/alginate beads for bone regeneration: bioactivity, biocompatibility and reactive oxygen species activity [PDF]
Materials for Biological Applications. 105, 109971. 2019, 2021 A very small number of biomaterials investigated for bone regeneration was reported as able to prevent the oxidative stress. In this study beads based on alginate hydrogel and mesoporous glasses (MG) containing different amounts of cerium oxides (Ce3+/Ce4+) exhibiting antioxidant properties were investigated as a good approach to mimic the action of ...

On the anti-cancer effect of cold atmospheric plasma and the possible role of catalase-dependent apoptotic pathways [PDF]
Cells 2020, 9, 2330, 2020 Cold atmospheric plasma (CAP) is a promising new agent for (selective) cancer treatment, but the underlying cause of the anti-cancer effect of CAP is not well understood yet. Among different theories and observations, one theory in particular has been postulated in great detail and consists of a very complex network of reactions that are claimed to ...

Polymer coated cerium oxide nanoparticles as oxidoreductase-like catalysts [PDF]
ACS Appl. Mater. Interfaces 2020, 12, 37, 42056 - 42066, 2020 Cerium oxide nanoparticles have been shown to mimic oxidoreductase enzymes by catalyzing the decomposition of organic substrates and reactive oxygen species. This mimicry can be found in superoxide radicals and hydrogen peroxides, harmful molecules produced in oxidative stress asso-ciated diseases.

Catalytically Potent and Selective Clusterzymes for Modulation of Neuroinflammation Through Single-Atom Substitutions [PDF]
Nature Communications,2020, 2020 Emerging artificial enzymes with reprogrammed and augmented catalytic activity and substrate selectivity have long been pursued with sustained efforts. The majority of current candidates rely on noble metals or transition metal oxides with rather poor catalytic activity compared with natural molecules.
