Sensing the dynamics of oxidative stress using enhanced absorption in protein-loaded random media

Olivier Martin, Christian Santschi, Guillaume Suarez

Reactive oxygen species play a key role in cell signalling and oxidative stress mechanisms, therefore, sensing their production by living organisms is of fundamental interest. Here we describe a novel biosensing method for extracellular detection of endoge ...

Imp2 controls oxidative phosphorylation and is crucial for preserving glioblastoma cancer stem cells

Johan Auwerx, Richardus Houtkooper, Ivan Stamenkovic, Michalina Janiszewska

Growth of numerous cancer types is believed to be driven by a subpopulation of poorly differentiated cells, often referred to as cancer stem cells (CSCs), that have the capacity for self-renewal, tumor initiation, and generation of nontumorigenic progeny. ...

The response of Desulfotomaculum reducens MI-1 to U(VI) exposure: a transcriptomic study

Rizlan Bernier-Latmani, Elena Cristina Dalla Vecchia

Desulfotomaculum reducens is the first Gram-positive sulfate- and metal-reducing bacterium for which the transcriptomic response to uranium exposure has been evaluated. The genes upregulated during fermentative growth in the presence of U(VI) as compared t ...

Structure, solution chemistry, antiproliferative actions and protein binding properties of non-conventional platinum(II) compounds with sulfur and phosphorus donors

Angela Casini

Twelve Pt(II) complexes with cis-PtP2S2 pharmacophores (where P-2 refers to two monodentate or one bidentate phosphane ligand and S-2 is a dithiolato ligand) were prepared, characterized and evaluated as potential antiproliferative agents. The various comp ...

Four-electron oxygen reduction by Tetrathiafulvalene

Hubert Girault, Astrid Johana Olaya Avendano, Péter Kalman Péchy, Jérôme Florian Gonthier, Peiyu Ge

The four-electron reduction of oxygen by tetrathiafulvalene (TTF) in acidified 1,2-dichloroethane and at the acidified water/1,2-dichloroethane interface has been observed. Spectroscopy and ion transfer voltammetry results suggest that the reaction proceed ...
