Human Dental Pulp Stem Cell Secretome Restores Ischemic Stroke–Impaired Motor and Cognitive Functions by Reprogramming Redox and Inflammatory Signaling

Advanced Science, EarlyView.
Human dental pulp stem cell secretome emerges as a cell‐free therapeutic strategy for ischemic stroke by reprogramming redox and inflammatory signaling. hDPSC secretome‐derived antioxidant and immunomodulatory factors suppress the TLR4–NOX–ROS–NF‐κB axis, reduce microglial inflammatory responses and apoptosis, and promote neurogenesis, angiogenesis ...

Functional and structural mimics of superoxide dismutase enzymes [PDF]

, 2008
Superoxide dismutase (SOD) enzymes form important defence line in living organisms. Through a dismutation reaction they transform the highly reactive superoxide radical ion to oxygen and hydrogen peroxide.

Tight Regulation of Extracellular Superoxide Points to Its Vital Role in the Physiology of the Globally Relevant Roseobacter Clade

mBio, 2019
There is a growing appreciation within animal and plant physiology that the reactive oxygen species (ROS) superoxide is not only detrimental but also essential for life.

Effects of dopaminergic drugs on superoxide dismutase: implications for senescence

, 1993
Both (-)-deprenyl and pergolide have been found to induce superoxide dismutase (SOD) in rat striata. There are several reports showing that strains or species with higher levels of SOD live longer.

Studies on superoxide dismutase inhibition and application of methods to study metal ion participation in complication of diabetes [PDF]

, 2012
Studies on Superoxide Dismutase Inhibition We used NMR relaxation rates to study reactions of the enzyme superoxide dismutase (SOD) with low molecular weight polyphenolic compounds. While the compounds appeared to inhibit SOD, we discovered evidence that

Effects of recombinant superoxide dismutase on manganese superoxide dismutase gene expression in gerbil hippocampus after ischemia.

, 1994
We reported that recombinant human superoxide dismutase ameliorates delayed neuronal death in the postischemic gerbil hippocampus. Since postischemic induction of copper-zinc superoxide dismutase messenger RNA was abolished by this treatment, oxygen ...

Polyethylene glycol-conjugated superoxide dismutase fails to augment brain superoxide dismutase activity in piglets.

, 1991
We studied the effect of intravenously administered polyethylene glycol-conjugated superoxide dismutase (8,000 units/kg) on brain superoxide dismutase activity in 44 1-2-week-old piglets in the absence and presence of global cerebral ischemia and ...

Engineering‐Modulated Molybdenum Enzymes Strategy for Tumor‐Specific Metabolic‐Immunotherapy

Advanced Science, EarlyView.
Biodegradable molybdenum sulfide nanoparticles were synthesized via a one‐pot strategy to increase molybdenum enzyme activity and thus effectively potentiate anti‐tumor immunity by integrating molybdenum‐based metalloimmunotherapy with hydrogen sulfide gas therapy.

Interrelated influence of light and Ni on Trichodesmium growth

Frontiers in Microbiology, 2013
Our previous laboratory study revealed that insufficient Ni supply can limit nitrogen fixation in Trichodesmium, a primary diazotrophic phytoplankton in the tropical and subtropical oceans.

Photoinhibition of photosystem II in tobacco plants overexpressing glutathione reductase and poplars overexpressing superoxide dismutase

, 1999
We studied photoinhibition in two cultivars of tobacco (Nicotiana tabacum L,) expressing the bacterial gor gene In the cytosol and in four lines of poplar (Populus tremula x P, alba) expressing the FeSOD gene of Arabidopsis thaliana in the chloroplast ...
