Protirelin acetate 醋酸普罗瑞林; Thyrotropin-releasing-hormone acetate; TRH acetate

产品介绍 Protirelin Acetate 是一种高度保守的神经肽,发挥促甲状腺激素 (TSH) 水平的激素控制作用,及神经调节功能。
生物活性

Protirelin Acetate is a highly conserved neuropeptide that exerts the hormonal control of thyroid-stimulating hormone (TSH) levels as well as neuromodulatory functions.

体外研究
体内研究

Protirelin (TRH) is an evolutionarily ancient neuropeptide, having its origin before the divergence of protostomes and deuterostomes, and may ancestrally have been involved in the control of postembryonic growth and reproduction. The effect of the thyrotropin-releasing hormone (Protirelin, TRH), one of the hypothalamic releasing hormones, on body temperature is investigated in the rat. Protirelin, in doses of 1, 5, 10 and 20 mg/kg, is injected intraperitoneally to male Wistar rats weighing 200-250 g. Protirelin causes a temporary rise in body temperature dose-dependently. The thyroidectomized rats injected 20 mg/kg of Protirelin which induces a significant hyperthermia in the sham-operated animals, fail to show a rise in body temperature. The present results suggest that a release of thyroid hormone might participate in the hyperthermic action of Protirelin.
