AIMS The pathophysiological role of iron in Parkinson's disease (PD) was assessed by a chelation strategy aimed at reducing oxidative damage associated with regional iron deposition without affecting circulating metals. Translational cell and animal models provided concept proofs and a delayed-start (DS) treatment paradigm, the basis for preliminary(More)
Challenges today concern chronic myeloid leukemia (CML) patients resistant to imatinib. There is growing evidence that imatinib-resistant leukemic cells present abnormal glucose metabolism but the impact on mitochondria has been neglected. Our work aimed to better understand and exploit the metabolic alterations of imatinib-resistant leukemic cells.(More)
Elesclomol is a first-in-class investigational drug currently undergoing clinical evaluation as a novel cancer therapeutic. The potent antitumor activity of the compound results from the elevation of reactive oxygen species (ROS) and oxidative stress to levels incompatible with cellular survival. However, the molecular target(s) and mechanism by which(More)
Vemurafenib/PLX4032, a selective inhibitor of mutant BRAFV600E, constitutes a paradigm shift in melanoma therapy. Unfortunately, acquired resistance, which unavoidably occurs, represents one major limitation to clinical responses. Recent studies have highlighted that vemurafenib activated oxidative metabolism in BRAFV600E melanomas expressing PGC1α.(More)
F14512, an epipodophyllotoxin derivative equipped with a spermine moiety, is selectively taken up by the polyamine transport system over-active in tumor cells. F14512 was identified as a selective anticancer agent with a broad spectrum of antitumor activities and is currently undergoing phase I clinical trial in onco-hematology. However, the mechanism by(More)
Parkinson's disease (PD) is a complex illness characterized by progressive dopaminergic neuronal loss. Several mechanisms associated with the iron-induced death of dopaminergic cells have been described. Ferroptosis is an iron-dependent, regulated cell death process that was recently described in cancer. Our present work show that ferroptosis is an(More)
