Induction of vasoactive intestinal peptide gene expression and prolactin secretion by insulin-like growth factor I in rat pituitary cells: evidence for an autoparacrine regulatory system.

abstract：:Ovarian hormones, including 17β-estradiol, are implicated in numerous physiological processes, including sleep. Beginning at puberty, girls report more sleep complaints than boys, which is maintained throughout the reproductive life stage. Sleep problems are exacerbated during the menopausal transition, evidenced by g...

Although IGF-I is known to mediate many of the effects of GH, it is not yet clear whether all effects of GH are completely dependent on the IGF-I system. To evaluate the biological effects of the GH/IGF-I axis on muscle growth, we administrated recombin...
