Calcitonin eel acetate (Calcitonin eel acetate (57014-02-5 Free base)) is the regulation of calcium homeostasis thyroid hormone peptide.

Eel calcitonin and its analog were always more potent than salmon calcitonin, but the efficacy of the three polypeptides was comparable. In cultured anterior pituitary cells, the inhibitory effect on phosphoinositide hydrolysis observed after chronic treatment with calcitonin was accompanied by a reduction of prolactin release. In contrast, a single treatment of cultured anterior pituitary cells with eel calcitonin or its analog eel calcitonin induced an increase of inositol phosphate accumulation, while salmon calcitonin was inactive. Accordingly, eel and eel calcitonin, but not salmon calcitonin, induced a slight but significant stimulation of prolactin secretion[1].
