Reactive oxygen species (ROS) serve as cell signaling molecules for normal biologic processes. However, the generation of ROS can also provoke damage to multiple cellular organelles and processes ...

Researchers from Japan find that certain antioxidant enzymes, called selenoproteins, significantly contribute to fighting ...

Many foods are often advertised for their antioxidant properties. Antioxidants counteract what are known as reactive oxygen ...

Reactive oxygen production and the ensuing cellular response can be strongly influenced by lifestyle factors such as the intensity and frequency of exercise. Traditionally, ROS are viewed as imposing ...

This jump-starts signaling pathways inside the cell that spur the production of reactive oxygen species (ROS) and antimicrobial compounds, which are secreted to combat the pathogen. PAMP-triggered ...

Our cells use oxygen to generate energy by burning nutrients to keep various processes in the cell working. While making this energy in the mitochondria (the cell’s power plants), the cell also ...

Spending enough time in the sun without adequate protection can leave us looking and presumably feeling like a lobster ready for the plate.

Increased production of reactive oxygen species occurs in sickle cell disease, evident as increased pro-oxidants (FORT) and reduced anti-oxidants (FORD). This has been demonstrated using a novel point ...
