Oxidative Stress News and Research

RSS

Oxidative Stress is a condition in which antioxidant levels are lower than normal. Antioxidant levels are usually measured in blood plasma.

Previously Unknown Protein Reveals RNA Repair Mechanism in Humans

Ribonucleic acids (RNAs) are single-stranded molecules that are found in all living organisms’ cells. As “transcripts” of human genes, mRNAs, for instance, play a role in the translation of genetic information by bearing the instructions for the production of a protein in their own sequence.

Revealing an Unanticipated Mechanism for Chaperone-Mediated Ribosome Repair

Researchers have discovered that if oxidative stress destroys protein factories known as ribosomes, repair crews may go in to assist in repairing the damage so that production may restart rapidly.

Discovering H2O2 sensing capacity in plants that control immunity

All aerobic organisms produce the molecule hydrogen peroxide (H2O2). When present in low concentrations, it acts as a crucial secondary signal to control a variety of biological processes, including but not limited to plant-microbe interactions, abiotic stress tolerance, pollen tube growth, root hair formation, leaf cell expansion, and Casparian strip formation.
