In the lamprey, adrenocorticotropin (ACTH) and melanotropins (MSHs) are produced from two distinct precursors, proopiocortin (POC) and proopiomelanotropin (POM). Both POC and POM have been suggested to be glycoproteins. The present study aimed to demonstrate glycoconjugates in ACTH and MSH cells in the pituitary of adult sea lampreys (Petromyzon marinus) by means of a lectin histochemistry. A total of 19 kinds of lectins were tested. ACTH cells were distributed in both the rostral pars distalis and the proximal pars distalis, and were stained positively with N-acetylglucosamine binding lectins (i. e., succinylated wheat germ agglutinin), N-acetylgalactosamine binding lectins (i. e., soybean agglutinin), D-mannose binding lectins (i. e., Lens culinaris agglutinin), and D-galactose binding lectins (i. e., Erythrina cristagall lectin). MSH cells were distributed in the pars intermedia, and were stained with N-acetylgalactosamine binding lectins (i. e., Dolichos biflorus agglutinin), D-mannose binding lectin (Pisum sativum agglutinin) and D-galactose binding lectins (i. e., peanut agglutinin). These results suggested that ACTH and MSH cells produce different types of glycoconjugates which may be attributed to the difference in glycoconjugate moieties between the precursor proteins, POC and POM.
