A structure-based mechanism of cisplatin resistance mediated by glutathione transferase P1-1

Paul Joseph Dyson, Laure Menin, Wee Han Ang

Cisplatin [cis-diamminedichloroplatinum(II) (cis-DDP)] is one of the most successful anticancer agents effective against a wide range of solid tumors. However, its use is restricted by side effects and/or by intrinsic or acquired drug resistance. Here, we ...

Genetic Polymorphism Associated Prefrontal Glutathione and Its Coupling With Brain Glutamate and Peripheral Redox Status in Early Psychosis

Rolf Gruetter, Lijing Xin, Kim Do, Benoît Schaller, Huanxiang Lu

BACKGROUND: Oxidative stress and glutathione (GSH) metabolism dysregulation has been implicated in the pathophysiology of schizophrenia. GAG-trinucleotide repeat (TNR) polymorphisms in the glutamate-cysteine ligase catalytic gene (GCLC), the rate-limiting ...

Differential coral bleaching—Contrasting the activity and response of enzymatic antioxidants in symbiotic partners under thermal stress

Thomas Krüger

Mass coral bleaching due to thermal stress represents a major threat to the integrity and functioning of coral reefs. Thermal thresholds vary, however, between corals, partly as a result of the specific type of endosymbiotic dinoflagellate (Symbiodinium sp ...

Molecular Engineering of Pyrido[3,4-b]pyrazine-Based Donor-Acceptor-pi- Acceptor Organic Sensitizers: Effect of Auxiliary Acceptor in Cobalt- and Iodine-Based Electrolytes

Michael Graetzel, Shaik Mohammed Zakeeruddin, Fabrizio Giordano, Jean-David Décoppet, Bo Liu

Due to the ease of tuning its redox potential, the cobalt-based redox couple has been extensively applied for highly efficient dye-sensitized solar cells (DSSCs) with extraordinarily high photovoltages. However, a cobalt electrolyte needs particular struct ...

Characterization of the surfaceome of the metal-reducing bacterium Desulfotomaculum reducens

Rizlan Bernier-Latmani, Romain Hamelin, Diego Chiappe, Elena Suvorova Buffat, Elena Cristina Dalla Vecchia, Paul Pao-Yun Shao

Desulfotomaculum reducens strain MI-1 is a Gram-positive, sulfate-reducing bacterium also capable of reducing Fe(III). Metal reduction in Gram-positive bacteria is poorly understood. Here, we investigated Fe(III) reduction with lactate, a non-fermentable s ...

Symbiont diversity and coral bleaching: An antioxidant view on thermal stress

Thomas Krüger

The functioning of coral reef systems, as biodiversity hotspots, is largely dependent on the symbiotic association between dinoflagellate symbionts (Symbiodinium spp.) and scleractinian coral hosts. The breakdown of this symbiosis (coral bleaching), as a r ...

Metal reduction and sporulation in Desulfotomaculum reducens

Elena Cristina Dalla Vecchia

The genera Desulfotomaculum and Clostridium, belonging to the phylum Firmicutes, comprise Gram-positive, low G+C genomic content, anaerobic, spore- forming bacteria. Desulfotomaculum is a metabolically and environmentally versatile genus capable of growing ...

Antioxidant plasticity and thermal sensitivity in four types of Symbiodinium sp.

Thomas Krüger

Warmer than average summer sea surface temperature is one of the main drivers for coraltemperature is one of the main drivers for coral bleaching, which describes the loss of endosymbiotic dinoflagellates (genus: Symbiodinium) in reef-building corals. Past ...

Sensing hydrogen peroxide by carbon nanotube/horseradish peroxidase bio-nanocomposite

László Forró, Arnaud Magrez, Endre Horvath, Klara Hernadi

H2O2 is a product of reactions catalysed by several oxidase enzymes and it is essential in environmental and pharmaceutical analyses. The most commonly used enzyme in understanding the biological behaviour of catalysed oxidation of H2O2 is horseradish pero ...

Phytoextraction of zinc, zinc oxide, copper and copper oxide in hydroponic solution with gibberellic acid and EDDS amendments by Lolium perenne

Flore Alice Margot Dupuich

This work was focused on the phytoextraction of zinc, copper, zinc oxide and copper oxide by Lolium perenne cultivated in hydroponic conditions, with gibberellic acid (GA) and ethylenediamine-N,N’-disuccinic acid (EDDS) amendments tested separately and in ...
