Mitochondria can dictate your fate, especially if you’re a stem cell

Redoxoma Highlights | Mitochondria can dictate your fate, especially if you’re a stem cell  Maria F. Forni

Known for over a century, mitochondria have become, during the last four decades, an important subject of research within several disciplines. This is mostly due to the fact that this organelle comprises the site of oxidative phosphorylation, the citric acid cycle, fatty acid oxidation, the urea cycle and the biosynthesis of iron-sulphur centres and haem. Moreover, mitochondria are an important redox-signaling node. Indeed, the bioenergetic status of a cell is dependent on the overall quality and relative abundance of the mitochondrial population it harbors. Recent evidence suggests that the control of mitochondrial mass and morphology occurs through the processes of fusion


Free radicals: should clinicians pay attention to them?

by Protasio L. da Luz*

Within the Cepid-Redoxoma, we are deeply involved in redox research and we consider this very important, of course. However, it is interesting at times to see how some meaningful outsiders interpret the area. The Radical-Free Corner challenged a highly experienced academic clinician-scientist, who kindly accepted this task (he happens to have been the Editor’s doctorate supervisor – a minor conflict of interest, I confess)

(Editor’s comment)

Oxidative stress pervades several areas of Medicine: aging, cancer, atherosclerosis and other degenerative conditions, principally. Several studies claim that it is the cause of aging. But while there is evidence for
