A partially purified fraction made up of two putative cytotoxic subtilisin-like fungal serine proteases has been recently reported to exhibit apoptosis-inducing activity in MCF7 cells [9] and more recently, Pushparajah et al. [52] synthesised a functional recombinant lectin-like fungal immunomodulatory protein using cDNA of L. rhinocerotis, which exhibit cytotoxicity against cancer cell lines. This evidence concerns the gene PROS1 and cancer.
