POMC neuron METTL14/m6A/YTHDC1/YTHDF2 pathways safeguard energy balance, body weight, and metabolism [PDF]

Nature Communications
METTL14 mediates N6-methyladenosine (m6A) RNA modification, while YTHDC1 and YTHDF2 specifically bind m6A-methylated RNA to regulate RNA fate. POMC neurons constitute the core of the central melanocortin circuit, and POMC deficiency causes obesity in ...

Generation and characterization of POMC-tdTomato reporter human pluripotent stem cell lines [PDF]

Stem Cell Research
Proopiomelanocortin (POMC) is a precursor polypeptide that undergoes extensive, tissue-specific post-translational processing. It is expressed in several tissues, including pituitary gland, hypothalamus, brain stem, and skin.

Mild Impairment of Mitochondrial OXPHOS Promotes Fatty Acid Utilization in POMC Neurons and Improves Glucose Homeostasis in Obesity

Cell Reports, 2018
Summary: Mitochondrial oxidative phosphorylation (OXPHOS) and substrate utilization critically regulate the function of hypothalamic proopiomelanocortin (POMC)-expressing neurons.

Differential expression of POMC-processing genes in corticotroph tumors [PDF]

Endocrine Oncology
Objective: Corticotroph tumors (CTs) derive from the TBX19 lineage and are functioning (FCTs) or nonfunctioning (NFCTs). In FCTs, the main pathogenic variants are found in USP8, enhancing proopiomelanocortin (POMC) transcription through epidermal growth ...

Casein kinase 1α is required to maintain murine hypothalamic pro-opiomelanocortin expression

iScience, 2023
Summary: Hypothalamic pro-opiomelanocortin (POMC) neuron development is considered to play an essential role in the development of obesity. However, the underlying mechanisms remain unclear.

Adult-born proopiomelanocortin neurons derived from Rax-expressing precursors mitigate the metabolic effects of congenital hypothalamic proopiomelanocortin deficiency

Molecular Metabolism, 2021
Objective: Proopiomelanocortin (POMC) neurons of the hypothalamic arcuate nucleus are essential regulators of energy balance. Selective loss of POMC production in these cells results in extreme obesity and metabolic comorbidities.

Hypothalamic agrp and pomc mRNA Responses to Gastrointestinal Fullness and Fasting in Atlantic Salmon (Salmo salar, L.)

Frontiers in Physiology, 2020
The orexigenic agouti-related protein (AgRP) and the anorexigenic pro-opiomelanocortin (POMC) are crucial players in the control of feed intake in vertebrates, yet their role in teleosts has not been fully established.

SK3 in POMC neurons plays a sexually dimorphic role in energy and glucose homeostasis

Cell & Bioscience, 2022
Background Pro-opiomelanocortin (POMC) neurons play a sexually dimorphic role in body weight and glucose balance. However, the mechanisms for the sex differences in POMC neuron functions are not fully understood.

Marchf6 E3 ubiquitin ligase critically regulates endoplasmic reticulum stress, ferroptosis, and metabolic homeostasis in POMC neurons

Cell Reports, 2023
Summary: The metabolic prohormone pro-opiomelanocortin (POMC) is generally translocated into the endoplasmic reticulum (ER) for entry into the secretory pathway.

Hypothalamic Pomc expression restricted to GABAergic neurons suppresses Npy overexpression and restores food intake in obese mice

Molecular Metabolism, 2020
Objective: Hypothalamic arcuate proopiomelanocortin (Arc-POMC) neurons are involved in different physiological processes such as the regulation of energy balance, glucose homeostasis, and stress-induced analgesia.
