Iron is an essential micronutrient for all eukaryotes. However, iron deficiency anemia is the most extended nutritional disorder worldwide. Thus, our main objective consists on deciphering the molecular mechanisms that eukaryotic cells utilize to regulate the response to iron deficiency. For this purpose, we use the yeast Saccharomyces cerevisiae as a model organism and biotechnological tool, paying special attention to transcriptional, post-transcriptional and metabolic regulation strategies. We use a multidisciplinary approach that includes Molecular Biology, Biochemistry, Microbiology, Genetics, Cellular Biology and "Omic" techniques.
