Role of insulin-like growth factor 1, sex and corticosteroid hormones in male major depressive disorder

BMC Psychiatry, 2021
Background Hormones of the hypothalamic–pituitary–gonadal (HPG), hypothalamic–pituitary–adrenal (HPA), and hypothalamic–pituitary–somatotropic (HPS) axes are potentially involved in major depressive disorder (MDD), but these hormones have not been ...

AMPK is essential for energy homeostasis regulation and glucose sensing by POMC and AgRP neurons [PDF]

, 2007
Hypothalamic AMP-activated protein kinase (AMPK) has been suggested to act as a key sensing mechanism, responding to hormones and nutrients in the regulation of energy homeostasis.

Crossover of the hypothalamic pituitary-adrenal/interrenal (HPA), -thyroid (HPT), and -gonadal (HPG) axes in testicular development

Frontiers in Endocrinology, 2014
Besides the well-known function of thyroid hormones (THs) for regulating metabolism, it has recently been discovered that THs are also involved in testicular development in mammalian and non-mammalian species.
