Thiaminylated adenine nucleotides — chemical synthesis, structural characterization and natural occurrence (2009)

Frederich, Michel, Delvaux, David, Gangolf, Marjorie, Dive, Georges, Mazzucchelli, Gabriel, Elias, Benjamin, ...

Thiamine and its three phosphorylated derivatives (mono-, di- and triphosphate) occur naturally in most cells. Recently, we reported the presence of a fourth thiamine derivative, adenosine thiamine...

Mercury immune toxicity in harbour seals: links to in vitrotoxicity (2008)

Das, Krishna, Siebert, Ursula, Gillet, Audrey, Dupont, Aurélie, Di-Poï, Carole, Fonfara, Sonja, ...

Abstract Background Mercury is known to bioaccumulate and to magnify in marine mammals, which is a cause of great concern in terms of their general health. In particular, the immune system is known...

Proteome alteration induced by hTERT transfection of human fibroblast cells (2008)

Mazzucchelli, Gabriel, Gabelica, Valérie, Smargiasso, Nicolas, Fleron, Maximilien, Ashimwe, Wilson, Rosu, Frédéric, ...

Background: Telomerase confers cellular immortality by elongating telomeres, thereby circumventing the Hayflick limit. Extended-life-span cells have been generated by transfection with the human...
