Prospects for enhancement of the soluble antioxidants, ascorbate and glutathione

, 2001
Ascorbic acid (vitamin C) and the tripeptide thiol, glutathione gamma-glutamyl cysteinyl glycine (glutathione) are the major low molecular weight soluble antioxidants in plant cells.

Characterization of an L-Ascorbate Catabolic Pathway with Unprecedented Enzymatic Transformations [PDF]

, 2019
L-Ascorbate (vitamin C) is ubiquitous in both our diet and the environment. Ralstonia eutropha H16 (Cupriavidus necator ATCC 17699) uses L-ascorbate as sole carbon source but lacks the genes encoding the known catabolic pathways.

SiDT1 Defines Plant Architecture Reminiscent of Green Revolution in Foxtail Millet

Advanced Science, EarlyView.
SiDT1 encodes a GA3‐oxidase that creates a semi‐dwarf, lodging‐resistant architecture reminiscent of the rice Green Revolution. The resulting ideotype performs well under dense planting and provides a valuable genetic resource for high‐yield, mechanized foxtail millet production. ABSTRACT Foxtail millet (Setaria italica) is a drought‐tolerant C4 cereal

The ascorbate-driven reduction of extracellular ascorbate free radical by the erythrocyte is an electrogenic process [PDF]

, 2001
Erythrocytes can reduce extracellular ascorbate free radicals by a plasma membrane redox system using intracellular ascorbate as an electron donor. In order to test whether the redox system has electrogenic properties, we studied the effect of ascorbate ...

Chemoselective Metabolomics via a Modular Reactivity‐Encoding Platform

Advanced Science, EarlyView.
Conventional LC–MS underrepresents numerous metabolites due to heterogeneous ionization efficiencies and matrix interference. Here, we introduce a modular reactivity‐encoding platform (MREP) comprising four alkyne‐tagged probes that selectively derivatize key functional groups, followed by unified click‐chemistry capture to eliminate matrix components ...

PolyG Fibrils Coalesce Into Nuclear Ribbons That Engage Proteostasis Machinery in Neuronal Intranuclear Inclusion Disease

Advanced Science, EarlyView.
In NIID, expanded NOTCH2NLC repeats give rise to nuclear polyG inclusions. Tracer‐guided in situ cryo‐electron tomography enables cross‐scale structural analysis from mouse brain to native neuronal nuclei, revealing dense‐core/peripheral‐halo inclusions built from compact polyG ribbons.

Suppression of tomato SlGGP aggravates methyl viologen-mediated oxidative stress

Biologia Plantarum, 2016
Ascorbate (AsA) is an important antioxidant that can scavenge reactive oxygen species to protect plant cells against oxidative stress. Guanosine 5'-diphosphate (GDP)-L-galactose phosphorylase (GGP) is a key enzyme in the AsA biosynthetic pathway.

Renal Clearable Luminogenic Reporter for Ultrasensitive Influenza Virus Imaging and Efficient Antiviral Therapies Monitoring in Living Mice

Advanced Science, EarlyView.
A viral luminogenic reporter with chemiluminescence/fluorescence dual‐response and efficient renal clearance was developed for non‐invasive imaging and urinalysis of H1N1 virus protease, allowing for remote detection of H1N1 virus infections and monitoring of antiviral therapeutic efficacy in living mice.

Interaction ammonium-nitrate: Response to oxidative stress in chicory plants [PDF]

, 2010
The aim of this work was to study, as a function of the different availability of nitrogen in the reduced form, mineral and organic, the induction of the synthesis of some ROS-scavenging molecules and the evolution of some enzymatic activities such as ...

Targeting the KCNC3‐Dependent Anterior Insular‐Lateral Orbitofrontal Cortex Glutamatergic Circuit Attenuates Post‐Traumatic Anxiety

Advanced Science, EarlyView.
Frontal lobe traumatic brain injury is associated with hyperactivity of an insular–orbitofrontal circuit in both patients and mice. By combination of integrating functional imaging, cell‐type–specific circuit manipulation, single‐cell transcriptomics, and whole‐cell recordings, this work identifies the downregulation of the potassium channel KCNC3 in ...
