摘要: Abstract Helodermin is a VIP/secretin-like 35-amino acid peptide originally isolated from the venom of lizard Gila monster. Recently, helodermin-immunoreactive material was demonstrated in mammalian salivary glands, brain and gut. In present study 8 human medullary thyroid carcinomas as well 4 normal glands were examined immunocytochemically for presence helodermin using an antiserum raised against helodermin-(5–35) that does not cross-react with VIP or secretin. Cells displaying helodermin-like immunoreactivity found all tumours except one. On whole cells had same distribution those storing calcitonin, suggesting coexistence two peptides most tumour cells. Also C-cells displayed immunoreactivity. The results suggest chemically related to constituent carcinoma C-cells.
