ACTH influences steroid hormone secretion by both rapid short-term mechanisms that take place within minutes and slower long-term actions. The rapid actions of ACTH include stimulation of cholesterol delivery to the mitochondria where the P450scc enzyme is located. P450scc catalyzes the first step of steroidogenesis that is cleavage of the side ...
In a large-scale study, 84.3 percent of men with androgenetic alopecia who were treated with minoxidil for 12 months rated it as either very effective, effective or moderately effective at ...
ACTH stimulates uptake of cholesterol and synthesis of pregnenolone.
