POMC-specific Modulation of Metabolic and Immune Pathways via Melanocortin-3 Receptor Signaling

• This proteomic study provides a nuanced understanding of the melanocortin-3 receptor (MC3R) and its ligand-specific effects on metabolic and immune pathways. Utilizing thermal proteome profiling with tandem mass spectrometry, we uncovered the distinct influences of adrenocorticotropic hormone (ACTH), α-melanocyte-stimulating hormone (α-MSH), and γ-melanocyte-stimulating hormone (γ-MSH) on protein thermal stability and pathway activation. ACTH uniquely affected NADPH-related metabolic proteins, α-MSH significantly modulated the IL-6 pathway via STAT3, and γ-MSH prominently activated interferon signaling. All ligands shared involvement in the cAMP-PKA-CREB and varied impacts on PI3K and ERK pathways, crucial for energy metabolism. Additionally, ligand-specific responses in mitochondrial protein stability suggest a role in cellular energy generation.
