WebData suggest that the loss of ACTH peptide expression in these late passage cells is in part due to the loss of the POMC signal sequence. ACTH stimulates IL-18 expression in … WebACTH is derived from the cleavage of POMC by proprotein convertase-1. 5–9 ACTH binds to steroidogenic cells of both the zona fasciculata and reticularis, activating adrenal steroidogenesis. It also has a trophic effect on adrenal tissue; therefore, ACTH deficiency determines adrenocortical atrophy and decreases the capacity to secrete glucocorticoids. WebAdrenocorticotrophin (ACTH) is derived by cleavage from the precursor, pro-opiomelanocortin (POMC), and depending on the degree of processing by the tissue or tumor, there is the potential for a number of ACTH-related peptides to be secreted from POMC expressing cells.
