Mitochondrial dysfunction and oxidative damage are at the origin of numerous neurodegenerative
diseases like Friedreich ataxia and Alzheimer and Parkinson diseases. Friedreich …

Oceanic phytoplankton species have highly efficient mechanisms of iron acquisition, as they
can take up iron from environments in which it is present at subnanomolar concentrations. …

Diphenyl ether herbicides induce an accumulation of protoporphyrin IX in plant tissues. By
analogy to human porphyria, the accumulation could be attributed to decreased (Mg or Fe)-…

The YFH1 gene is the yeast homologue of the human FRDA gene, which encodes the
frataxin protein. Saccharomyces cerevisiae cells lacking the YFH1 gene showed very low …

The yeast, Saccharomyces cerevisiae,contains a transcription activator, Aft1p, that regulates
the transcription of the high affinity iron transport system genes. This report describes the …

Candida albicans, unlike Saccharomyces cerevisiae, was able to use extracellular haemin
as an iron source. Haemin uptake kinetics by C. albicans cells showed two phases: a rapid …

Phytoplankton growth is limited in vast oceanic regions by the low bioavailability of iron. Iron
fertilization often results in diatom blooms, yet the physiological underpinnings for how …

CP12 is an 8.5-kDa nuclear-encoded chloroplast protein, isolated from higher plants. It
forms part of a core complex of two dimers of phosphoribulokinase (PRK), two tetramers of …

Diagnosis of muscular dystrophies is currently based on invasive methods requiring muscle
biopsies or blood tests. The aim of the present study was to identify urinary biomarkers as a …

We investigated iron uptake mechanisms in five marine microalgae from different ecologically
important phyla: the diatoms Phaeodactylum tricornutum and Thalassiosira pseudonana, …
