Data from: Gene transcription in sea otters (Enhydra lutris): development of a diagnostic tool for sea otter and ecosystem health

Herein we describe methodology for the development of quantitative real time polymerase chain reaction (qPCR) assays to measure differential transcript levels of multiple immune-function genes in the sea otter (Enhydra lutris); sea otter specific, qPCR primer sequences for the genes of interest are defined.

We establish a “reference” range of transcripts for each gene in a group of clinically healthy captive and free-ranging sea otters. The 10 genes of interest represent multiple physiological systems that play a role in immuno-modulation, inflammation, cell protection, tumor suppression, cellular stress-response, xenobiotic metabolizing enzymes, antioxidant enzymes, and cell-cell adhesion. The cycle threshold (CT) measures for most genes were normally distributed; the complement cytolysis inhibitor was the exception.
