Research interests
Secondary metabolites from marine organisms: source of stress and biologically active compounds.
Metabolites produced by marine organisms have received increasing attention in the last decade. Notably, it has been shown that diatoms, unicellular algae, widely distributed in most aquatic habitats, produce a wide range of bioactive metabolites. Some of them (collectively termed oxylipins, including polyunsaturated aldehydes PUAs, hydroxyacids and oxo-acids) showed toxic effects on marine invertebrates. I am particularly interested in studying the molecular basis of cellular mechanisms that underlie the responses of benthic organisms to environmental stress. Currently I am studying the effects of diatom-derived oxylipins on embryonic and larval development from the molecular point of view, using sea urchin as model system
Sponges seem also to be particularly rich sources of bioactive compounds which show antiviral, antibacterial and anti-inflammatory activities. They are also promising candidates as anticancer drugs, considering that three of the four commercial anticancer drugs available have been derived from marine sponges. Several anti-inflammatory metabolites have been isolated from sponges belonging to the class of the Demospongiae, including cavernolide from Fasciospongia cavernosa, contignasterol from Petrosia contignata and cyclolinteinone from Cacospongia linteiformis. I am interested in studying the potential effects of a methanol extract from the marine sponge, Geodia cydonium and identification of its biologically active compounds.
Finally, I am interested in marine genomics and epigenetics. The aim is to investigate the functioning and the biology of marine organisms by the implementation of high-throughput genomic approaches. Through the development of genomic and proteomic tools we intend to conduct research in the areas of comparative and functional genomics aiming to the evolution, development of diversity and environmental adaptation.
