WebIn the anterior pituitary, POMC is processed to ACTH by the prohormone convertase, PC1 and packaged in secretory granules ready for stimulated secretion. In response to stress, corticotrophin releasing hormone (CRH), stimulates release of ACTH from the pituitary cell which in turn causes release of glucocorticoids from the adrenal gland. WebOct 1, 1995 · To explore whether the POMC peptide is present as a reservoir or synthesized de novo in Thy‐1 + dendritic cells, Northern blot analysis using 30‐mer oligonucleotide probe for α‐MSH/ACTH precursor POMC was carried out in total RNA from these cells. Northern blot analysis revealed the presence of POMC like mRNA transcript.
