Somatostatin

Meaning

Somatostatin, also known as Growth Hormone Inhibiting Hormone, is a peptide hormone that functions as a potent inhibitor of the secretion of several other hormones, neurotransmitters, and gastrointestinal peptides. Primarily produced in the hypothalamus, pancreas, and gastrointestinal tract, its main endocrine role is to suppress the release of Growth Hormone and Thyroid-Stimulating Hormone from the pituitary. It is a key negative regulator in the neuroendocrine system.
