Project Description

Uveal melanoma is the most frequent primary intraocular tumor, in Caucasian adults, and one that is very difficult to treat once it becomes metastatic. In fact, there is currently no effective treatment for metastatic uveal melanoma despite the significant progress in the area of cancer therapeutics. Isothiocyanates are phytochemicals derived from cruciferous vegetables and are responsible for exerting a plethora of anticancer (and other biological) effects, thus promoting their utilization in disease prevention and nutritional intervention.
The proposed project will build on current collaboration of the supervisory team with The Watercress Company, UK (provider of 60% of the UK watercress market) and the Northumbria University NUOMICs Centre in order to investigate the role of isothiocyanates in uveal melanoma chemoprevention. Processes for bench-scale characterization and extraction of isothiocyanates derived from natural watercress samples will be developed. The ability of several isothiocyanates (i.e. sulphoraphane, benzyl, phenethyl, allyl and iberin) to induce a chemopreventive role will be demonstrated by utilizing an in vitro experimental model using human uveal melanoma cell lines. Moreover, genomic, proteomic and epigenetic methodologies will be employed in order to identify and characterize key genes, and associated proteins, which become deregulated during the process of the disease development. Such knowledge will not only (i) delineate underlying mechanisms(s) involved in uveal melanoma, and how isothiocyanates may be involved, but also (ii) lead to development of biomarkers descriptive of the disease pathophysiology which could open up the way for “designing” more efficient therapeutic and/or nutritional intervention strategies.
Overall, the proposed project adopts a multidisciplinary approach by bringing together expertise from food, nutritional and biomedical sciences to address an unmet clinically significant need regarding treatment of uveal melanoma, a vision and life threatening cancer.
