Untersuchung der ACTH-Sensitivität bei Normalpersonen: Einfluß eines Polymorphismus im ACTH-Rezeptor-Gen
Der ACTH-Rezeptor ist ein funktionell und strukturell wichtiger Rezeptor innerhalb der Hypothalamus-Hypophysen-Nebennieren-Achse. Seine Expression ist entscheidend für die ACTH-Sensitivität der Nebennierenrinde und damit für die Glukokortikoidsekretion bei akutem und chronischem Stress. Außerdem …

Nahrungsabhängige ACTH- und Kortisolsekretion bei Patienten mit Nebennieren-Zufallstumor
… werden. Der Kortisolanstieg erwies sich als ACTH-vermittelt. Es fanden sich bei diesen Patienten signifikant höhere Kortisolwerte im 24h-Sammelurin und niedrigere Nüchtern-ACTH-Werte im Vergleich zu den restlichen Inzidentalom-Patienten. Bei den von uns untersuchten Inzidentalom-Patienten …

Mechanisms behind the lipid-lowering effects of ACTH - Studies in different experimental models
Abstract Adrenocorticotrophic hormone (ACTH) has strong and direct lipid-lowering effects in man. All apoB-containing lipoproteins, i.e. VLDL, LDL, Lp(a), are reduced by 25-30%. In contrast, levels of HDL increase about 10%. In hepatic cell cultures, ACTH inhibits expression and secretion of apoB. …

The Effects of Actinomycin D and Acth on Circadian Steroidogenesis of Hamster Adrenals
Rhythmicity is predominant in nature. Sunrise is followed by sunset in a highly predictable periodic sequence. Living organisms are known to be influenced by such periodically occurring phenomena. De Mairan, as early as 1729, observed leaf movements of plants and found these variations to be …

Effects of Acth on Plasma Concentrations of Cortisol and Progesterone and on Embryonic Survival in Swine
… study was to determine if elevated levels of ACTH and cortisol such a those present during stress might have a detrimental effect on embryonic survival in swine. In a preliminary investigation daily injections of either 100 or 200 i.u. of ACTH or 100 or 200 USP units of Cortrophin-Zn were used …

Der Einfluss von Adrenostatika auf die Hormonbiosynthese und die Expression des ACTH-rezeptors in boviner Nebennierenrinden-Primärkultur
… System in seiner Funktion und Regulation. ACTH ist dabei der wichtigste Stimulator in der Steroidbiosynthese. Es vermittelt seine Wirkung über einen spezifischen G-Proteingekoppelten Rezeptor, den ACTH-R. Bei verschiedenen Erkrankungen dieses Systems kommt es zu einer vermehrten Produktion …

The effect of ACTH and progesterone on semen characteristics, blood hormones and testicular histology in the bull
… Holstein bulls were injected with 200 IU ACTH every 8 hr for 6 days. In Experiment 2, two groups of three yearling Holstein bulls each were injected daily with crystalline progesterone in propylene glycol (.84 mg/kg body wt) for 21 days. Semen characteristics (sperm abnormalities, percent …

Long-Term Hypoxia Regulates Cortisol Biosynthesis in the Ovine Fetal Adrenal Cortex
… cells (FACs) were untreated, treated with ACTH, treated in combination with ACTH precursors (POMC and 22-kDa pro-ACTH), or pre-treated with H-89 and or UO126 followed by ACTH treatment. Following ACTH treatment, cortisol biosynthesis increased in both groups but values were significantly …

Interaction of ACTH and Estradiol in the Regulation of Growth, Differentiation, and Steroidogenic Maturation of the Baboon Fetal Adrenal Gland
… determined whether the growth of, as well as ACTH receptor and P-450 enzyme messenger ribonucleic acid and/or protein levels in the baboon fetal adrenal are dependent upon fetal pituitary ACTH during mid and late gestation and the mechanism by which placental estrogen modulates ACTH actions. …

System identification of cortisol secretion : characterizing pulsatile dynamics
… to pulses of adreno-corticotropic hormone (ACTH) released from the anterior pituitary; in return, cortisol has a negative feedback effect on ACTH release. Modeling cortisol secretion and the interactions between ACTH and cortisol allows for quantifying normal and abnormal physiology and can …

Effects of Glucocorticoids and Limited Nursing on the Digestive Enzyme Ontogeny and Growth of Nursing Piglets (Maltase, Sucrase, Lactase, Amylase, Acth)
… (HYD) and adrenocorticotropic hormone (ACTH) on the developing carbohydrate digestive enzymes and growth rate of nursing piglets. The response of these enzymes to increased creep feed consumption, produced by partial weaning, was also investigated. A total of 87 litters of piglets were …

Evolution of Melanocortin-2 Receptor Activations: Studies on a Mammal and a Fish
… between melanocortin-2 receptor (MC2R) and ACTH are the most complicated in melanocortin receptor gene family. A comparative study on the activation of human and rainbow trout MC2R will provide a useful model system for understanding how ACTH emerged as the sole ligand for the MC2R of bony …
