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

open access: yesEnvironmental 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 ...

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

open access: yesJournal 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.

New mutations at the imprinted Gnas cluster show gene dosage effects of Gsα in postnatal growth and implicate XLαs in bone and fat metabolism, but not in suckling [PDF]

open access: yes, 2012
The imprinted Gnas cluster is involved in obesity, energy metabolism, feeding behavior, and viability. Relative contribution of paternally expressed proteins XLαs, XLN1, and ALEX or a double dose of maternally expressed Gsα to phenotype has not been ...

Effectiveness and Safety of Setmelanotide in a Patient With a Heterozygous PCSK1 Deficiency

open access: yesObesity, EarlyView.
ABSTRACT Setmelanotide, a melanocortin 4 receptor (MC4R) agonist, is a promising pharmacological treatment option for people with rare monogenic obesity conditions affecting the leptin‐melanocortin signaling pathway, including proprotein convertase subtilisin/kexin type 1 (PCSK1) gene mutations.

Pro-Opiomelanocortin and Melanocortin Receptor 3 and 4 Mutations in Genetic Obesity

open access: yesBiomolecules
Genetic obesity results from loss-of-function mutations, including those affecting the leptin–melanocortin system, which regulates body weight. Pro-opiomelanocortin (POMC)-derived neurohormones act as ligands for melanocortin receptors (MCRs), regulating

Pancreatic cancer cachexia: a review of mechanisms and therapeutics. [PDF]

open access: yes, 2014
Over the last decade, we have gained new insight into the pathophysiology of cachexia associated with pancreatic cancer. Unfortunately, its treatment is complex and remains a challenge.

Identification of the Translation Start Site of the Human Melanocortin 3 Receptor [PDF]

open access: yesObesity Facts, 2012
<i>Background:</i> The melanocortin-3-receptor (MC3R) is a G-protein coupled receptor participating in hypothalamic energy metabolism. So far, it was assumed that the translation of the human MC3R starts at the non-conserved first ATG, however, a second evolutionary conserved ATG is located 37 amino acids downstream.

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

open access: yesPediatric 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.

Fasting-induced activity changes in MC3R neurons of the paraventricular nucleus of the thalamus

open access: yesLife Science Alliance
This study assesses how the brain responds to fasting and the role of melanocortin 3 receptor neurons within the paraventricular nucleus of the thalamus, measured using immunohistochemistry, microscopy, chemogenetics, and behavioral analysis.
