Many small peptides exert their effects at very low concentrations. For example, a number of vertebrate hormones (Chapter 23) are small peptides. These include oxytocin (nine amino acid residues), which is secreted by the posterior pituitary and stimulates uterine contractions bradykinin (nine residues), which inhibits inflammation of tissues and thyrotropin-releasing factor (three residues), which is formed in the hypothalamus and stimulates the release of another hormone, thyrotropin, from the anterior pituitary gland. Some extremely toxic mushroom poisons, such as amanitin, are also small peptides, as are many antibiotics. [Pg.86]

The thyroid-pituitary-hypothalamus axis controls thyroid hormone homeostasis. Thyrotropin-releasing hormone (TRH), released from the hypothalamus, stimulates the synthesis and release of thyroid-stimulating hormone (thyrotropin, TSH) from the anterior pituitary. TSH increases the release of thyroid hormones by several mechanisms, including stimulation of the I pump. While lower than normal levels of T3 and T4 cause an exaggerated response of the pituitary to TRH, released thyroid hormones, in feedback control, blunt the stimulating action of TRH on the pituitary. For further discussion of TSH and TRH biochemistry, see, for example, the review by Kannan48. [Pg.1502]

In amino acids 3/(C0-Cv) varies between 1-5 and 3-5 Hz. (57, 58) For the proline residue in the tripeptide hormone thyrotropin-releasing factor (TRF, LGlu-His-Pro-NH2) Haar et al. (60) report that 3/(C0-Cy) <0-5 and 37(Ca-Cg) = 3-9 Hz. Using the angular dependence of 3/(C-C) predicted by Barfield et al., (66, 52) Haar and co-workers (60) conclude that the proline residue in TRF is preferentially in the endo conformation in contrast to proline itself.

Amiodarone has intrinsic effects on the thyroid and thyroid hormone production besides those related to excessive iodine intake, and this means that it induces thyroid dysfunction more frequently than any other iodine-containing pharmaceutical.

Thyroid-stimulating hormone (thyrotropin) is a glycoprotein (molecular weight, 28,000-30,000 daltons) secreted by the anterior lobe of the pituitary gland that is necessary for the growth and function of the thyroid. A recombinant thyrotropin a useful for the detection and treatment of cancer was approved by the U. S. FDA in November 1998. [Pg.228]
