Article Summary
Redox Biol. 2014 Jan 10;2:206-10.A review of the mitochondrial and glycolytic metabolism in human platelets and leukocytes: Implications for their use as bioenergetic biomarkers.Kramer PA, Ravi S, Chacko B, Johnson MS, Darley-Usmar VM.Department of Pathology, UAB Mitochondrial Medicine Laboratory, Center for Free Radical Biology, University of Alabama at Birmingham, Birmingham, AL, USA. This opens up the possibility that circulating platelets and leukocytes can sense metabolic stress in patients and serve as biomarkers of mitochondrial dysfunction in human pathologies.
Sci Transl Med. 2014 Jan 29;6(221).Antioxidants accelerate lung cancer progression in mice.Sayin VI, Ibrahim MX, Larsson E, Nilsson JA, Lindahl P, Bergo MO.Sahlgrenska Cancer Center, Department of Molecular and Clinical Medicine, Institute of Medicine, University of Gothenburg, SE-405 30 Gothenburg, Sweden. NAC and vitamin E increase tumor cell proliferation by reducing ROS, DNA damage, and p53 expression in mouse and human lung tumor cells. Inactivation of p53 increases tumor growth to a similar degree as antioxidants and abolishes the antioxidant effect. Thus, antioxidants accelerate tumor growth by disrupting the ROS-p53 axis.
Proc Natl Acad Sci U S A. 2014 Jan 21;111(3):960-5. UCP2 transports C4 metabolites out of mitochondria, regulating glucose and glutamine oxidation.Vozza A, Parisi G, De Leonardis F, Lasorsa FM, Castegna A, Amorese D, Marmo R, Calcagnile VM, Palmieri L, Ricquier D, Paradies E, Scarcia P, Palmieri F, Bouillaud F, Fiermonte G.Department of Biosciences, Biotechnologies, and Biopharmaceutics and Center of Excellence in Comparative Genomics, University of Bari, 70125 Bari, Italy. This treatise show that UCP2 catalyzes an exchange of malate, oxaloacetate, and aspartate for phosphate, and that it exports C4 metabolites from mitochondria to the cytosol in vivo. Our findings also provide evidence that UCP2 activity limits mitochondrial oxidation of glucose and enhances glutaminolysis.
PLoS One. 2014 Jan.Improved metabolic health alters host metabolism in parallel with changes in systemic xeno-metabolites of gut origin.Campbell C, Grapov D, Fiehn O, Chandler CJ, Burnett DJ, Souza EC, Casazza GA, Gustafson MB, Keim NL, Newman JW, Hunter GR, Fernandez JR, Garvey WT, Harper ME, Hoppel CL, Meissen JK, Take K, Adams SH.Genome Center, University of California Davis, Davis, California, USA.

Cell Mol Life Sci. 2014 May 28.Biosynthesis and roles of phospholipids in mitochondrial fusion, division and mitophagy.Zhang Q, Tamura Y, Roy M, Adachi Y, Iijima M, Sesaki H.Department of Cell Biology, Johns Hopkins University School of Medicine, Baltimore, MD, USA. Three conserved mitochondrial dynamin-related GTPases (i.e., mitofusin, Opa1 and Drp1) mediate mitochondrial fusion and division. In addition to dynamins, recent studies demonstrated that phospholipids in mitochondria also play key roles in mitochondrial dynamics by interacting with dynamin GTPases and by directly changing the biophysical properties of the mitochondrial membranes.
Cell Metab. 2014 May 6;19(5):757-66.Mitohormesis.Yun J, Finkel T.Center for Molecular Medicine, National Heart, Lung and Blood Institute, NIH, Bethesda, MD 20892, USA. This view has been largely supplanted by the concept that mitochondria are fully integrated into the cell and that mitochondrial stresses rapidly activate cytosolic signaling pathways that ultimately alter nuclear gene expression. Remarkably, this coordinated response to mild mitochondrial stress appears to leave the cell less susceptible to subsequent perturbations.
Curr Biol. 2014 May 19;24(10).ROS function in redox signaling and oxidative stress.Schieber M, Chandel NS.Division of Pulmonary and Critical Care Medicine, Department of Medicine, The Feinberg School of Medicine, Northwestern University, Chicago, IL 60611, USA. In this review we discuss the two faces of ROS -redox biology and oxidative stress- and their contribution to both physiological and pathological conditions. Redox biology involves a small increase in ROS levels that acti- vates signaling pathways to initiate biological processes, while oxidative stress denotes high levels of ROS that result in damage to DNA, protein or lipids.
