Corticotropin (ACTH) acts directly on amygdala neurons to down-regulate corticotropin-releasing hormone gene expression. [PDF]

, 2001
The hormone corticotropin (ACTH) is employed as therapy for diverse neurological disorders, but the mechanisms for its efficacy remain unknown. ACTH promotes the release of adrenal steroids (glucocorticoids), and most ACTH effects on the central nervous ...

Prenatal betamethasone–postnatal N‐methyl‐D‐aspartic acid model of spasms: Update on mechanisms and treatments

Epilepsia Open, EarlyView.
Abstract Infantile epilepsy spasms syndrome (IESS), formerly known as infantile spasms or West Syndrome, is a severe epilepsy syndrome affecting about 3 in 10,000 newborns in the United States. Characterized by clusters of epileptic spasms, interictal hypsarrhythmia, and developmental delays, IESS has diverse causes, including structural‐metabolic ...

Inconsistent Transcriptomic Responses to Hexabromocyclododecane in Japanese Quail: A Comparative Analysis of Results From Four Different Study Designs

Environmental Toxicology and Chemistry, EarlyView.
Abstract Efforts to use transcriptomics for toxicity testing have classically relied on the assumption that chemicals consistently produce characteristic transcriptomic signatures that are reflective of their mechanism of action. However, the degree to which transcriptomic responses are conserved across different test methodologies has seldom been ...

A Setmelanotide-like Effect at MC4R Is Achieved by MC4R Dimer Separation

Biomolecules, 2022
Melanocortin 4 receptor (MC4R) is part of the leptin-melanocortin pathway and plays an essential role in mediating energy homeostasis. Mutations in the MC4R are the most frequent monogenic cause for obesity.

Alpha‐Synuclein Promotes Anterograde Vesicle Transport in Melanocytes and Melanoma Cells: A Pro‐Survival Function

Journal of the Chinese Chemical Society, EarlyView.
Model for how α‐syn modulates the positioning of endolysosomes in melanoma cells. (a) α‐syn tethers endolysosomes to the plasma membrane, a last step in anterograde transport. (b) Loss of α‐syn expression causes the loss of the tethering function, which leads to perinuclear vesicle clustering. Reproduced from the open access article.

Expanding the genotypic spectrum of PCSK1 deficiency: A novel mutation in severe neonatal diarrhea

JPGN Reports, EarlyView.
Abstract Among congenital diarrhea and enteropathies (CODEs), proprotein convertase subtilisin/kexin type 1 (PCSK1) deficiency is a rare monogenic disorder, associated with severe neonatal diarrhea and polyendocrinopathies. We report an 18‐day‐old male neonate, born to consanguineous parents, presenting with persistent watery diarrhea, metabolic ...

Involvement of melanocortin receptor accessory proteins (MRAPs) in the function of melanocortin receptors

General and Comparative Endocrinology, 2013
The melanocortin system integrates different agonists, competitive or inverse agonists, and receptors. Recent investigations have also discovered a specific system of melanocortin receptor accessory proteins (MRAPs) that are involved in the regulation of the functional expression of these receptors.

Monogenic and syndromic obesity in children: Clinical recognition, genetics, and precision management

Pediatric Investigation, EarlyView.
Monogenic and syndromic obesity in children often arises from defects in the leptin–melanocortin pathway. Understanding these rare genetic causes not only clarifies mechanisms of appetite regulation but also enables precision therapies, offering hope beyond lifestyle interventions.

MRAP2 modifies the signaling and oligomerization state of the melanocortin-4 receptor

Nature Communications
The melanocortin-4 receptor is a G protein-coupled receptor and a key regulator of appetite and metabolism. It can interact with the melanocortin-receptor accessory protein 2, a single transmembrane helix protein known to interact with several different ...
