Journal Article
Catalase-overexpressing Thymocytes Are Resistant to Glucocorticoid-induced Apoptosis and Exhibit Increased Net Tumor Growth
TL;DR: In this paper, the authors showed that dexamethasone, a synthetic glucocorticoid, causes a down-regulation of several antioxidant defense enzymes and proteins, including catalase and thioredoxin, concomitant with the induction of apoptosis in WEHI7.2 mouse thymoma cells.
Journal ArticleDOI
A redox signature score identifies diffuse large B-cell lymphoma patients with a poor prognosis.
Margaret E. Tome,David B. F. Johnson,David B. F. Johnson,Lisa M. Rimsza,Lisa M. Rimsza,Robin A. Roberts,Robin A. Roberts,Thomas M. Grogan,Thomas M. Grogan,Thomas P. Miller,Thomas P. Miller,Larry W. Oberley,Larry W. Oberley,Margaret M. Briehl,Margaret M. Briehl +14 more
TL;DR: Patients with DLBCL with the worst prognosis had decreased expression of catalase, glutathione peroxidase, manganese superoxide dismutase, and VDUP1, a protein that inhibits thioredoxin activity, according to the outcome predictor score.
Journal ArticleDOI
Different mechanisms of increased proteolysis in atrophy induced by denervation or unweighting of rat soleus muscle
Marc E. Tischler,Sara Rosenberg,Soisungwan Satarug,Erik J. Henriksen,Christopher R. Kirby,Margaret E. Tome,Peter B. Chase +6 more
TL;DR: In this paper, the authors compared denervated and unweighted soleus muscle with chloroquine and methylamine and found that denervation increased the lysosomal proteolysis.
Journal ArticleDOI
Molecular modes of action of cantharidin in tumor cells
Thomas Efferth,Rolf Rauh,Stefan Kahl,Maja T. Tomicic,Herbert Böchzelt,Margaret E. Tome,Margaret M. Briehl,Rudolf Bauer,Bernd Kaina +8 more
TL;DR: In this article, the authors show that cantharidin (CAN), the active principle ingredient from the blister beetle, Mylabris, has anti-tumor activity, but the cytotoxic mechanism is unknown.
Journal ArticleDOI
Induction of mitochondrial changes in myeloma cells by imexon.
Katerina Dvorakova,Caroline N. Waltmire,Claire M. Payne,Margaret E. Tome,Margaret M. Briehl,Robert T. Dorr +5 more
TL;DR: It is reported that imexon has cytotoxic activity in other malignant cell lines including NCI-H929 myeloma cells and NB-4 acute promyelocytic leukemia cells, whereas normal lymphocytes and U266 myELoma cells are substantially less sensitive.
