Abstract: Significance Superoxide and other reactive oxygen species (ROS) are commonly regarded as harmful progenitors of biological stress and death, but this view has been changing. Indeed, many phytoplankton actively generate extracellular superoxide under ideal growth… read more here.

Abstract: Superoxide and other reactive oxygen species (ROS) shape microbial communities and drive the transformation of metals and inorganic/organic matter. Taxonomically diverse bacteria and phytoplankton produce extracellular superoxide during laboratory cultivation. Understanding the physiological reasons for… read more here.

DOI: 10.3389/fcvm.2022.942736
Abstract: Superoxide radical plays an important role in redox cell signaling and physiological processes; however, overproduction of superoxide or insufficient activity of antioxidants leads to oxidative stress and contributes to the development of pathological conditions such… read more here.

Abstract: Oral treatment of apolipoprotein E-knockout (ApoE-KO) mice with the putative sirtuin 1 (SIRT1) activator resveratrol led to a reduction of nicotinamide adenine dinucleotide phosphate (NADPH) oxidase activity in the heart. In contrast, the SIRT1 inhibitor… read more here.

DOI: 10.3390/ijms23062906
Abstract: Acute kidney injury (AKI) caused by ischemia followed by reperfusion (I/R) is characterized by intense anion superoxide (O2•−) production and oxidative damage. We investigated whether extracellular vesicles secreted by adipose tissue mesenchymal cells (EVs) administered… read more here.
