California sea lion plasma chronic DAT biomarkers via 2D-GE

ABSTRACT: Domoic acid toxicosis (DAT) in California sea lions (Zalophus californianus) is caused by exposure to the marine biotoxin domoic acid and has been linked to massive stranding events and mortality. Diagnosis is based on clinical signs in addition to the presence of domoic acid in body fluids. Chronic DAT further is characterized by reoccurring seizures progressing to status epilepticus. Diagnosis of chronic DAT is often slow and problematic, and minimally invasive tests for DAT have been the focus of numerous recent biomarker studies. The goal of this study was to retrospectively profile plasma proteins in a population of sea lions with chronic DAT and those without DAT using two dimensional gel electrophoresis in an effort to discover whether individual, multiple, or combinations of protein and clinical data could be utilized to identify sea lions with DAT. 49 spots were excised, digested and analyzed by MS/MS. These are the data.
