IGF1, which is mainly expressed in the hepatic tissue, can directly inhibit GH secretion in the somatotrophs of fish (50, 96, 97), birds (98, 99) and mammals (87, 92, 100), through a longloop negative feedback (by acting on the pituitary and/or on GHRH in the brain, Figure 1 ), but also indirectly by enhancing the hypothalamic release of somatostatin (101), and is considered the other major endocrine and local effector of the GH/IGF axis
