PTH plays a critical role in calcium metabolism in tetrapods. The primary site of PTH expression is the parathyroid glands, although it is also detected in the thymus and hypothalamus. Fish lack anatomically distinct parathyroid glands, and the first animals to evolve parathyroid glands were the amphibians. However, fish do have PTH family ligands and receptors, which are functionally similar to their mammalian counterparts. We report the expression patterns of duplicate zebrafish pth genes during embryogenesis. Both zebrafish pth1 and pth2 transcripts are expressed along the lateral line before the migration of the lateral line primordium and later in development Pth protein is detected in ..
