Summary Brevetoxins (PbTx) are highly potent polyether toxins produced during blooms of several species of marine dinoflagellates, most notably Karenia brevis. Brevenal is a nontoxic short-chain polyether that competes with PbTx for the active site on voltage-sensitive sodium charmels. Human consumption of shellfish contaminated with PbTxs results in neurotoxic shellfish poisoning (NSP). Additionally, blooms of K. brevis are potentially responsible for adverse human health effects such as respiratory irritation and airway constriction in coastal residents. The purpose of this study was to determine if PbTx could induce DNA damage in mammalian cells, and if so, if the damage could be antagonized by brevenal. Results from the single-cell gel electrophoresis assay, inhibition of cellular proliferation assay, chromosomal aberration assay, and disruption of signaling pathways via a Western Blot analysis demonstrate that PbTx is a potent inducer of mammalian cell damage, an effect which can be reduced or alleviated by brevenal.
