In Vitro Characterization of Human Growth Hormone
... Growth hormone (GH) is a 22 kD, 191-aa, pituitary-derived peptide hormone that is essential for postnatal growth. GH signals via binding to GH receptor (GHR), which initiates intracellular signal transduction pathways. This leads to activation of target genes, most importantly the one encoding insul ...

Clinical neurochemistry
Clinical neurochemistry is the field of neurological biochemistry which relates biochemical phenomena to clinical symptomatic manifestations in humans. While neurochemistry is mostly associated with the effects of neurotransmitters and similarly-functioning chemicals on neurons themselves, clinical neurochemistry relates these phenomena to system-wide symptoms. Clinical neurochemistry is related to neurogenesis, neuromodulation, neuroplasticity, neuroendocrinology, and neuroimmunology in the context of associating neurological findings at both lower and higher level organismal functions.
