Application

Protochordean octapeptide cionin is a structural hybrid of mammalian cholecystokinin (CCK) and gastrin with functions most similar to those of CCK. Cionin is used as a potent and efficient stimulator of gastric histamine release and acid secretion via a CCK-B receptor.

The protochordean octapeptide cionin is structurally a hybrid of mammalian cholecystokinin (CCK) and gastrin, and thus their possible common ancestor. To determine whether cionin behaves like CCK or gastrin, we examined its effect on canine fundic somatostatin cells and on

The critical phylogenetic position of ascidians leads to the presumption that neuropeptides and hormones in vertebrates are highly likely to be evolutionarily conserved in ascidians, and the cosmopolitan species Ciona intestinalis is expected to be an excellent deuterostome Invertebrate model

The protochordean octapeptide cionin is structurally a hybrid of mammalian cholecystokinin (CCK) and gastrin. An earlier study has shown that cionin in mammals stimulates gallbladder contraction and gastric somatostatin release, similarly to CCK-8. In the present study we examined the
