Journal ArticleDOI
A role for oxidative stress in apoptosis: oxidation and externalization of phosphatidylserine is required for macrophage clearance of cells undergoing Fas-mediated apoptosis.
V. E. Kagan,Bettina Gleiss,Yulia Y. Tyurina,Vladimir A. Tyurin,Carina Elenström-Magnusson,Shangxi Liu,F. Behice Serinkan,Antonio Arroyo,Joya Chandra,Sten Orrenius,Bengt Fadeel +10 more
TL;DR: The data suggest that the presence of PS-OX in conjunction with nonoxidized PS on the cell surface is an important signal for macrophage clearance of apoptotic cells.
Journal ArticleDOI
Coenzyme Q reductase from liver plasma membrane: purification and role in trans-plasma-membrane electron transport
José M. Villalba,Francisco Navarro,Francisco Córdoba,Antonio Serrano,Antonio Arroyo,Frederick L. Crane,Plácido Navas +6 more
TL;DR: The results support the involvement of p34 as a source of electrons for the trans-plasma-membrane redox system oxidizing NADH and support coenzyme Q as an intermediate electron carrier between NADh and the external acceptor ascorbate free radical.
Journal ArticleDOI
NADPH oxidase-dependent oxidation and externalization of phosphatidylserine during apoptosis in Me2SO-differentiated HL-60 cells. Role in phagocytic clearance.
Antonio Arroyo,Martin Modrianský,F. Behice Serinkan,Rosario I. Bello,Tatsuya Matsura,Jianfei Jiang,Vladimir A. Tyurin,Yulia Y. Tyurina,Bengt Fadeel,Valerian E. Kagan +9 more
TL;DR: The results indicate that NADPH oxidase-induced oxidative stress in neutrophil-like cells triggers apoptosis and subsequent recognition and removal of these cells through pathways dependent on oxidation and externalization of phosphatidylserine.
Journal ArticleDOI
Vitamin E and selenium deficiency induces expression of the ubiquinone-dependent antioxidant system at the plasma membrane
Francisco Navarro,Plácido Navas,John R. Burgess,Rosario I. Bello,R. de Cabo,Antonio Arroyo,J. M. Villalba +6 more
TL;DR: The results indicate that, in the absence of vitamin E and Se, enhancement of ubiquinone‐dependent reductase systems can fulfill the membrane antioxidant protection.
Journal ArticleDOI
Binding of fatty acids facilitates oxidation of cysteine-34 and converts copper-albumin complexes from antioxidants to prooxidants.
Y.A. Gryzunov,Antonio Arroyo,Jean-Louis Vigne,Qing Zhao,Vladimir A. Tyurin,Carl A. Hubel,Robin E. Gandley,Yury A. Vladimirov,Robert N. Taylor,Valerian E. Kagan +9 more
TL;DR: It is concluded that fatty acids regulate anti-/prooxidant properties of Cu-albumin via controlling redox status of Cys-34, which is a transition metal capable of undergoing one-electron oxidation-reduction conversions.
