Signal Transduction and Pathogenic Modifications at the Melanocortin-4 Receptor: A Structural Perspective [PDF]
The melanocortin-4 receptor (MC4R) can be endogenously activated by binding of melanocyte-stimulating hormones (MSH), which mediates anorexigenic effects. In contrast, the agouti-related peptide (AgRP) acts as an endogenous inverse agonist and suppresses

RoPE: A robust profile likelihood method for differential gene expression analysis
Abstract Variation in RNA‐Seq data creates modeling challenges for differential gene expression (DE) analysis. Statistical approaches address conventional small sample sizes and implement empirical Bayes or non‐parametric tests, but frequently produce different conclusions. Increasing sample sizes enable proposal of alternative DE paradigms.

The neural melanocortin receptors (MCRs), melanocortin-3 and -4 receptors (MC3R and MC4R), play essential non-redundant roles in the regulation of energy homeostasis. Interaction of neural MCRs and melanocortin-2 receptor accessory proteins (MRAPs, MRAP1

Pathophysiology of melanocortin receptors and their accessory proteins. [PDF]
The melanocortin receptors (MCRs) and their accessory proteins (MRAPs) are involved in regulation of a diverse range of endocrine pathways. Genetic variants of these components result in phenotypic variation and disease. The MC1R is expressed in skin and

MRAP2 inhibits β-arrestin recruitment to the ghrelin receptor by preventing GHSR1a phosphorylation
The melanocortin receptor accessory protein 2 (MRAP2) is essential for several physiological functions of the ghrelin receptor growth hormone secretagogue receptor 1a (GHSR1a), including increasing appetite and suppressing insulin secretion. In the absence of MRAP2, GHSR1a displays high constitutive activity and a weak G-protein-mediated response to ...

Promiscuity among the MRAPs. [PDF]
The melanocortin 2 receptor accessory protein (MRAP) was originally discovered to be an essential co-receptor for the ACTH receptor/melanocortin 2 receptor, and it physically interacts with this receptor and is required for receptor trafficking and ...

Gene expression profiling of tumour epithelial and stromal compartments during breast cancer progression [PDF]
The progression of ductal carcinoma in situ (DCIS) to invasive ductal carcinoma (IDC) marks a critical step in the evolution of breast cancer. There is some evidence to suggest that dynamic interactions between the neoplastic cells and the tumour ...

G protein-coupled receptors: what a difference a 'partner' makes [PDF]
G protein-coupled receptors (GPCRs) are important cell signaling mediators, involved in essential physiological processes. GPCRs respond to a wide variety of ligands from light to large macromolecules, including hormones and small peptides. Unfortunately,
