Research interests
The culture and rearing of marine organisms is fundamental to perform experiments and test hypotheses on the role played by various plant-derived compounds on model invertebrates. We developed several systems to rear and culture larvae and adults of marine invertebrates (one of them is under patent registration) and presently we culture both micro- and macro-algae, besides shrimps, molluscs and other marine invertebrates. Some of these organisms are used to test the effect of secondary metabolites on model invertebrates. In particular, the effect of benthic diatoms living on P. oceanica meadows on the sex reversal of the shrimp Hippolyte inermis is studied. Some compounds present in these diatoms induce an early apoptosis in the testis of the shrimp, eliciting sex reversal. We demonstrated that crude extracts of the diatoms may kill, very selectively, human cancer cells, in vitro. The elucidation of the active compound is still investigated. Finally, some wound-activated secondary metabolites present in various plants may influence the ecology and the behaviour of invertebrates and they are investigated as well, also in view of the ocean acidification processes that modulate the activity of volatile infochemicals. Therefore, the relationships between plant and animals are studied by means of structural and functional studies and the last are investigated taking into account the effect of secondary metabolites as physiology modulators and infochemicals for various invertebrates, especially when their effects might lead to new biotechnologies in the field of human medicine and aquaculture.
