  Epinephrine is an important neuroendocrine regulator to control growth hormone (GH) secretion in vertebrates. Somatolactin (SL), the latest member of the GH family, is a novel pituitary hormone with diverse functions in fish. In a previous report it was shown that epinephrine had a potent inhibitory effect on SL release in fish. However, very little is known about the mechanisms responsible for epinephrine inhibition of SL gene expression. In primary cultures of tilapia neurointermediate lobe (NIL) cells, epinephrine not only reduced SL mRNA levels, but could also abolish pituitary adenylate cyclase-activating polypeptide (PACAP)-stimulated SL gene expression. The inhibitory effects of epinephrine on SL gene expression were mimicked by additions of α2-adrenergic agonists clonidine and UK14304, whereas similar treatments with the α1-agonist cira..
