Cover Story: Chondrosia reniformis is a common mediterranean demosponge. In this paper, we identified a new cytotoxic protein (chondrosin) with selective activity against specific tumor cell lines. Chondrosin was extracted, purified and characterized through biochemical techniques. The procedure allowed to identify a 199-amino acid polypeptide. Cell death was determined by extracellular calcium intake, followed by cytoplasmic reactive oxygen species overproduction. The in silico modelling of chondrosin showed a high structural homology with the N-terminal region of the ryanodine receptor/channel. These results suggest a possible specific interaction of chondrosin with the Cav 1.3 ion voltage calcium channel expressed on the target cell membranes with consequent calcium-derived apoptosis.
