Impairment of Autophagy Causes Superoxide Formation and Caspase Activation in 661 W Cells, a Cell Line for Cone Photoreceptors, under Hyperglycemic Conditions

, 2020
Microvascular changes are the earliest adverse events in diabetic retinopathy, but recent studies have shown that oxidative stress induced by photoreceptors is associated with the development of the retinopathy. The purpose of this study was to determine

Cytochrome c and superoxide [PDF]

JBIC Journal of Biological Inorganic Chemistry, 2013
Wegerich et al. (J. Biol. Inorg. Chem. 18:429-440, 2013), working with singly modified human cytochromes c, claim to have found a new mechanism for the reduction of iron(III) cytochrome c by superoxide. I show that electron transfer by way of the solvent-accessible haem edge - a mechanism not considered by Wegerich et al.

Blood–Brain Barrier Regulation: Evolving From Classic Strategies to Electrochemical Ion and Reactive Oxygen Species Control

Advanced Healthcare Materials, EarlyView.
Conventional therapies suffer from poor blood–brain barrier (BBB) penetration and disordered ion/reactive oxygen species (ROS) homeostasis, hindering precise neurological treatment. Electrochemical strategies achieve accurate spatiotemporal regulation of neural homeostasis.

Role of reactive oxygen species in ultraviolet-induced photodamage of the skin

Cell Division
Reactive oxygen species (ROS), such as superoxides (O2 •−) and hydroxyl groups (OH·), are short-lived molecules containing unpaired electrons. Intracellular ROS are believed to be mainly produced by the mitochondria and NADPH oxidase (NOX) and can be ...

Production of Superoxide and Activity of Superoxide Dismutase in Rabbit Epididymal Spermatozoa [PDF]

Biology of Reproduction, 1982
Mature rabbit spermatozoa from the cauda epididymidis suspended in potassium Tris phosphate buffer at 24 degrees C produced O2.-, as measured by reduction of acetylated ferricytochrome c, with an intrinsic rate of 0.20 nmol/min per 10(8) cells. This rate increased to 1.80 nmol/min per 10(8) cells in the presence of 10 mM cyanide.
