WebMar 1, 2024 · Mice lacking both genes in POMC neurons have reduced energy expenditure on a high-fat diet (HFD) and gain more weight 12, 13. POMC-specific ATG5 KO mice have defective autophagy [14], and deletion of ATF4 results in ATG5-dependent autophagy and increased α-MSH production, leading to increased energy expenditure 12, 13 (Figure 1). 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 … See more POMC is cut (cleaved) to give rise to multiple peptide hormones. Each of these peptides is packaged in large dense-core vesicles that are released from the cells by exocytosis in response to appropriate stimulation: See more The levels of proopiomelanocortin (pomc) are regulated indirectly in some animals by the photoperiod. It is referred to the hours of light during a day and it changes across the seasons. Its regulation depends on the pathway of thyroid hormones that is regulated directly by … See more Mutations in this gene have been associated with early onset obesity, adrenal insufficiency, and red hair pigmentation. A study concluded that a polymorphism was associated with higher fasting insulin levels in the obese patients only. These findings support the … See more The POMC gene is located on chromosome 2p23.3. The POMC gene is expressed in both the anterior and intermediate lobes of the pituitary gland. This gene encodes a … See more The large molecule of POMC is the source of several important biologically active substances . POMC can be cleaved enzymatically into … See more A deletion mutation common in Labrador Retriever and Flat-Coated Retriever dogs is associated with increased interest in food and subsequent obesity. See more POMC is used as a target for a medication used to treat obesity in humans. The combination of bupropion and naltrexone acts via hypothalamic POMC neurons to decrease appetite. See more
