Biochem/physiol Actions

Adrenocorticotropic hormone (ACTH) is a polypeptide hormone thatstimulates adrenocortical activity. It is produced by the prohormoneproopiomelanocortin (POMC), which is synthesized in the corticotroph andmelanotroph cells found in the intermediate and anterior lobe of the pituitarygland and the arcuate nucleus of the hypothalamus. ACTH is also synthesized inthe skin. It plays a role in controlling steroidogenesis in the adrenal glandand prevents reactive oxygen species (ROS)-induced cell toxicity. Higher levelsof ACTH lead to skin hyperpigmentation due to the hyperstimulation ofmelanocytes, characteristic of primary adrenal insufficiency (PAI). Deficiencyof ACTH synthesis, receptors, or signaling is associated with adrenalinsufficiency.

Steroidogenic acute regulatory protein (StAR) transfers cholesterol over the inner mitochondrial membrane. In mammals, StAR controls this rate-limiting step of steroidogenesis, but its expression and regulation has not been well explored in fish. The present work investigates StAR mRNA expression

During human pregnancy, ACTH is produced by both the placenta and fetal pituitary. ACTH has been shown to cause vasodilatation in the adrenal cortex in vitro. In this context we have investigated the vasoactive effects of ACTH in the human

Exposure to stress is associated with susceptibility to disease and one stress mediator, norepinephrine, has been reported to enhance the adherence of enterohemorrhagic Escherichia coli O157:H7 (EHEC) to the colonic mucosa. We tested the hypothesis that adrenocorticotropic hormone (ACTH) and

Corticotropin-inhibiting peptide (CIP), the 7-38 fragment of human ACTH(1-39), is known to act as an antagonist of ACTH receptors. Accordingly, CIP has been found to inhibit ACTH-stimulated glucocorticoid secretion of dispersed rat adrenocortical cells, without per se affecting the basal
