Reduction of a-tocopherylquinone Model Compound With Various Reductant [PDF]

, 2001
In order to study the possibility of tranformation of a-tocopherylquinone (TQ) into a more oxidiseable compound and also to find out the recycling effect in the cells, an experiment was conducted by reducing the model compound 2-(3- hydroxy-3-methylbutyl)

Inhibition of SLC11A1‐Mediated Lysosomal Iron Accumulation in Microglia Promotes Repair Following White Matter Stroke

Advanced Science, EarlyView.
Genetic and pharmacological inhibition of SLC11A1 functioning as an H+/Fe2+ antiporter–mediated lysosomal iron accumulation in microglia promotes lysosomal lumen acidification, increases CTSD expression, enhances lysosomal myelin debris uptake and degradation, and promotes repair following white matter stroke. ABSTRACT White matter stroke (WMS) results

H2O2 Signature and Innate Antioxidative Profile Make the Difference Between Sensitivity and Tolerance to Salt in Rice Cells [PDF]

, 2018
Salt tolerance is a complex trait that varies between and within species. H2O2 profiles as well as antioxidative systems have been investigated in the cultured cells of rice obtained from Italian rice varieties with different salt tolerance.

The Regulatory Role of Iron Transporter SLC39A13 in Liver Fibrosis

Advanced Science, EarlyView.
SLC39A13/ZIP13, a newly discovered intracellular iron transporter, delivers iron to the ER/Golgi to catalyze procollagen hydroxylation during collagen maturation. Here, we systematically characterize the cell type‐specific functions of ZIP13 across distinct hepatic cell populations, and identify hepatic stellate cell‐specific ZIP13 as a promising and ...

Fulvic Acid Enhances Oat Growth and Grain Yield Under Drought Deficit by Regulating Ascorbate–Glutathione Cycle, Chlorophyll Synthesis, and Carbon–Assimilation Ability

Agronomy
Drought deficit inhibits oat growth and yield. Fulvic acid (FA) can enhance plant stress tolerance, but its effects on regulating the ascorbate–glutathione cycle, chlorophyll synthesis, and carbon–assimilation ability remain unclear.

Ascorbate deficient semi-dwarf asfL1 mutant of Lathyrus sativus exhibits alterations in antioxidant defense

Biologia Plantarum, 2012
An ascorbate-deficient semi-dwarf mutant asfL-1 was detected in 250 Gy γ-ray treated grass pea (Lathyrus sativus L.) cv. BioR-231. The mutant contained only 42 % of leaf and 20 % of root ascorbate content of mother control (MC).

Natural Variations of ZmRLR1 Mediate the Root Lodging Resistance of Maize by Regulating Root Ascorbate and Auxin Homeostasis

Advanced Science, EarlyView.
Root lodging severely limits crop yield and quality. We reveal that ZmRLR1, a plasma membrane b‐type cytochrome, regulates lodging resistance in maize through dual roles: modulating intracellular redox balance and functioning as a novel component of clathrin‐mediated endocytosis to influence auxin homeostasis. Moreover, natural variations in the ZmRLR1

Metarhizium anisopliaeMitigates the Phytotoxicity of Lead and Nanoplastics on Rice by Modifying Physiological, Transcriptomic, Metabolomic Activities, and Soil Microbiome

Advanced Science, EarlyView.
Metarhizium anisopliae alleviates the phytotoxic effects of polyethylene nanoplastics (NP) and lead (Pb) in rice by decreasing Pb uptake, restoring antioxidant and hormonal equilibrium, and promoting growth. Additionally, the fungus modifies the rhizosphere microbiota, enhancing both contaminant tolerance and plant growth, thereby effectively ...

Glutathione s-transferase as a marker of oxidative stress in human ejaculated spermatozoa from patients with pathospermia

Regulatory Mechanisms in Biosystems, 2018
It is believed that the most common causes of male infertility are impairment of spermatogenesis and sperm functions. Glutathione S-transferases (EC 2.5.1.18) play an important role in sperm physiology, specifically in antioxidant protection against ...

Ascorbic acid enhances the inhibitory effect of aspirin on neuronal cyclooxygenase-2-mediated prostaglandin E2 production. [PDF]

, 2006
Inhibition of neuronal cyclooxygenase-2 (COX-2) and hence prostaglandin E2 (PGE2) synthesis by non-steroidal anti-inflammatory drugs has been suggested to protect neuronal cells in a variety of pathophysiological situations including Alzheimer's disease ...
