Catastrophic disassembly of actin filaments via Mical-mediated oxidation. [PDF]

, 2017
Actin filament assembly and disassembly are vital for cell functions. MICAL Redox enzymes are important post-translational effectors of actin that stereo-specifically oxidize actin's M44 and M47 residues to induce cellular F-actin disassembly.

Genetic attenuation of ALDH1A1 increases metastatic potential and aggressiveness in colorectal cancer

Molecular Oncology, EarlyView.
Aldehyde dehydrogenase 1A1 (ALDH1A1) is a cancer stem cell marker in several malignancies. We established a novel epithelial cell line from rectal adenocarcinoma with unique overexpression of this enzyme. Genetic attenuation of ALDH1A1 led to increased invasive capacity and metastatic potential, the inhibition of proliferation activity, and ultimately ...

OH-Radical Oxidation of Lung Surfactant Protein B on Aqueous Surfaces [PDF]

, 2018
Air pollutants generate reactive oxygen species on lung surfaces. Here we report how hydroxyl radicals (·OH) injected on the surface of water react with SP-B_(1–25), a 25-residue polypeptide surrogate of human lung surfactant protein B.

Mitochondrial Thioredoxin System as a Modulator of Cyclophilin D Redox State [PDF]

, 2016
The mitochondrial thioredoxin system (NADPH, thioredoxin reductase, thioredoxin) is a major redox regulator. Here we have investigated the redox correlation between this system and the mitochondrial enzyme cyclophilin D.

Dimethyl fumarate combined with cisplatin at subcytotoxic doses sensitizes cervical cancer toward ferroptosis and apoptosis through GSH restriction and p53 (re)activation

Molecular Oncology, EarlyView.
Dimethyl fumarate (DMF) reduces growth of HPV‐positive cervical cancer spheroids and induces ferroptosis in cervical cancer cells via blocking SLC7A11/Glutathione (GSH) axis. Combination of subcytotoxic doses of DMF and cisplatin (CDDP) further suppresses spheroid growth and drives cell death in 2D culture models.

Structural and Functional Properties Changes of β-Conglycinin Exposed to Hydroxyl Radical-Generating Systems

Molecules, 2017
The objective of the present study was to examine the structural and functional changes of β-conglycinin exposed to oxidizing radicals produced by FeCl3/H2O2/ascorbic acid hydroxyl radical-generating system (HRGS) for 3 h at room temperature.

Decolouring bloodmeal: Consumption and potential recycling of peracetic acid [PDF]

, 2012
A method of deodorizing and decolouring bloodmeal using an equilibrium mixture of peracetic acid, hydrogen peroxide, acetic acid and water has been developed to improve its marketability as a source of protein for bioplastics.

Network divergence analysis identifies adaptive gene modules and two orthogonal vulnerability axes in pancreatic cancer

Molecular Oncology, EarlyView.
Tumors contain diverse cellular states whose behavior is shaped by context‐dependent gene coordination. By comparing gene–gene relationships across biological contexts, we identify adaptive transcriptional modules that reorganize into distinct vulnerability axes.

FORMATION OF LONG-LIVED REACTIVE SPECIES OF BLOOD SERUM PROTEINS BY THE ACTION OF HEAT

Alʹmanah Kliničeskoj Mediciny, 2016
Background: Proteins oxidized by the action of X-rays represent long-lived reactive species, which trigger the secondary generation of reactive oxygen species (ROS). A change in the hydrogen peroxide (H2O2) content induced by various physical impacts may

Acute oral sodium propionate supplementation raises resting energy expenditure and lipid oxidation in fasted humans [PDF]

, 2018
Short chain fatty acids (SCFAs), produced from fermentation of dietary fibre by the gut microbiota, have been suggested to modulate energy metabolism. Previous work using rodent models have demonstrated that oral supplementation of the SCFA propionate ...
