WebProopiomelanocortin. Pro-opiomelanocortin ( POMC) is a precursor polypeptide with 241 amino acid residues. POMC is synthesized in corticotrophs of the anterior pituitary from the 267-amino-acid-long polypeptide precursor pre-pro-opiomelanocortin ( pre-POMC ), by the removal of a 26-amino-acid-long signal peptide sequence during translation. [5] WebApr 24, 2024 · Given that ARC POMC neurons play a role in the control of food intake [30–34], we asked whether activation of TRPV1-like receptors in ARC POMC neurons is sufficient to reduce food intake. To test this possibility, animals were fasted for 6 h (from 1 PM to 7 PM) before drug infusion and capsaicin was directly infused into the ARC.
