Subject The present study utilizes lectin histochemistry and immunohistochemistry to examine the expression of glycoconjugates and parathyroid hormone-related peptide in the kidney of the red-spotted newt following parathyroidectomy. The parathyroid gland is known to be an important regulator of calcium homeostasis in vertebrates. Following parathyroidectomy in the red-spotted newt, calcium levels drop significantly but return to normal within 14 days. Results of lectin histochemistry revealed that parathyroidectomy affected glycoconjugates within proximal tubules of the newt kidney. Results show proximal tubule cells accumulated granules, which bound PTHrP antibody and also reacted to lectins specific for oligosaccharides associated with secretory proteins. These results suggest PTHrP may play a role in restoring plasma calcium following parathyroidectomy. The presence of granules, which bind PTHrP antibodies, suggests PTHrP is produced in the kidney and serves an autocrine or paracrine role as the calcemic factor in this species.
