The stimulation of growth hormone release by ACTH and its inhibition by somatostatin. 1976

J Köbberling, and H Jüppner, and R D Hesch

The rapid injection of 0.5 or 1.0 mg of tetracosacitid (Synacthen¿) was followed by a distinct increase of plasma growth hormone (GH) within 30 or 45 min in 5 of 7 normal volunteers. A second control test was performed in 3 of the 5 "responders" and 1 "non-responder" and showed a consistent reaction in all of them. The tests were then repeated in the 5 "responders" during an infusion of somatostatin (150 mug/h) and the GH response was totally abolished (3 subjects) or markedly reduced (2 subjects). Thus the ACTH induced GH release behaves in a manner similar to most other physiological or pharmacological stimuli of GH release. The cortisol output after ACTH was not altered by somatostatin.

D003366 Cosyntropin A synthetic peptide that is identical to the 24-amino acid segment at the N-terminal of ADRENOCORTICOTROPIC HORMONE. ACTH (1-24), a segment similar in all species, contains the biological activity that stimulates production of CORTICOSTEROIDS in the ADRENAL CORTEX.

D006854 Hydrocortisone The main glucocorticoid secreted by the ADRENAL CORTEX. Its synthetic counterpart is used, either as an injection or topically, in the treatment of inflammation, allergy, collagen diseases, asthma, adrenocortical deficiency, shock, and some neoplastic conditions.

D000324 Adrenocorticotropic Hormone An anterior pituitary hormone that stimulates the ADRENAL CORTEX and its production of CORTICOSTEROIDS. ACTH is a 39-amino acid polypeptide of which the N-terminal 24-amino acid segment is identical in all species and contains the adrenocorticotrophic activity. Upon further tissue-specific processing, ACTH can yield ALPHA-MSH and corticotrophin-like intermediate lobe peptide (CLIP).

D000328 Adult A person having attained full growth or maturity. Adults are of 19 through 44 years of age. For a person between 19 and 24 years of age, YOUNG ADULT is available. Adults
D013004 Somatostatin A 14-amino acid peptide named for its ability to inhibit pituitary GROWTH HORMONE release, also called somatotropin release-inhibiting factor. It is expressed in the central and peripheral nervous systems, the gut, and other organs. SRIF can also inhibit the release of THYROID-STIMULATING HORMONE; PROLACTIN; INSULIN; and GLUCAGON besides acting as a neurotransmitter and neuromodulator. In a number of species including humans, there is an additional form of somatostatin, SRIF-28 with a 14-amino acid extension at the N-terminal.

D013006 Growth Hormone A polypeptide that is secreted by the adenohypophysis (PITUITARY GLAND, ANTERIOR). Growth hormone, also known as somatotropin, stimulates mitosis, cell differentiation and cell growth. Species-specific growth hormones have been synthesized.
