Our laboratory investigates the potential of brevetoxins, which are the toxins produced by dinoflagellate alga during red tides, to cause DNA mutagenesis, alter cell cycle, and influence apoptosis in normal and neoplastic human lung cells. The action of brevetoxins at sodium channels, cytoplasmic or nuclear targets in lung tumors may result in a loss of normal regulation. However, it is unclear if this will lead to apoptosis and/or mitogenesis, if those responses will be dose-dependent, and if they will have environmental exposure implications or chemotherapeutic applications. Collaborative work on lung cancer with several researchers at the UF Cancer Center includes development and examination of murine cancer models.
I also have a strong interest in the species-dependent environmental/evolutionary relationships resulting in widely disparate levels of toxin sensitivity and resistance in aquatic invertebrates compared to marine mammals. This has led to a subspecialization in aquatic invertebrate histopathology and gastric gland function including protein and genetic expression profiling to identify biomarkers of aquatic invertebrate stress and detoxification mechanisms.
