Abstract

Pendrin is a membrane transport protein which functions as the transporter of chloride, bicarbonate, formate, and iodide. In this study, we characterized pendrin gene expression in various tissues of deer mice (Peromyscus maniculatus), a sentinel wildlife species. Deer mice were euthanized at post-natal day (PND) 21 (day of weaning) and PND 45 (24 days post-weaning) for tissue collection. A deer mouse-specific partial pendrin cDNA sequence was generated, from which Taqman-specific probe and primers were designed for quantification of mRNA equivalents of pendrin gene expression using real-time polymerase chain reaction (PCR). The expression profile was standardized to glyceraldehyde-3-phosphate dehydrogenase (GAPDH). Results indicate that the pendrin gene was expressed at different levels in the different tissues of developing deer mice relative to GAPDH expression. Expression in the tissues was determined to be age-dependent. Pendrin gene was highly expressed in the kidney, lungs and
