Nano‐Gs Protein Peptidomimetics: Rational Design of Gα C‐Terminus‐Derived Peptides Mimicking Key Components of Gs‐β2AR Interactions

Angewandte Chemie International Edition, EarlyView.
G protein‐coupled receptors (GPCRs) are major therapeutic targets. Modulating GPCR activity through intracellular sites is evolving. A structure‐ and computation‐assisted approach generated small G protein‐derived peptidomimetics targeting the intracellular binding crevice of the β2 adrenergic receptor mimicking features of the full G protein.

A Purine Nucleotide Biosynthesis Enzyme Guanosine Monophosphate Reductase Is a Suppressor of Melanoma Invasion

Cell Reports, 2013
Melanoma is one of the most aggressive types of human cancers, and the mechanisms underlying melanoma invasive phenotype are not completely understood. Here, we report that expression of guanosine monophosphate reductase (GMPR), an enzyme involved in de ...

Modulating Taste Perception in Newly Weaned Piglets: The Role of Palatability Additives in Enhancing Feed Intake and Performance

Animal Research and One Health, EarlyView.
Palatability enhancers modulate taste and smell, increasing feed acceptance, reducing weaning stress, and improving piglet performance. ABSTRACT The continuous growth of global agribusiness stimulates the search for alternatives that can enhance the performance and quality of life of production animals.

A Cooperative Release of Mitochondrial DNA From Platelets and Neutrophils Drives an Interferon Signature in Systemic Sclerosis

Arthritis &Rheumatology, EarlyView.
Objective Mitochondria are organelles with a hypomethylated circular genome. Mitochondrial DNA (mtDNA) in the systemic circulation has been implicated in inflammation. This study investigates the role of circulating DNA in systemic sclerosis (SSc) and the cellular mechanisms governing its release.

TWEAK/Fn14 Signaling Drives Oxidative Cardiac Injury in Systemic Lupus Erythematosus: Evidence From Patient Biomarker Studies, Lupus Mouse Models, and Cardiomyocyte Assays

Arthritis &Rheumatology, EarlyView.
Objective Cardiac involvement is a major cause of morbidity in systemic lupus erythematosus (SLE). Tumor necrosis factor–like weak inducer of apoptosis (TWEAK) is elevated in SLE, but its contribution to lupus‐associated cardiac injury is unclear. We investigated the role of TWEAK/fibroblast growth factor–inducible 14 (Fn14) signaling in SLE‐related ...

Molybdenum–Gold Nanoclusters Using 2-Mercapto-5-nitrobenzimidazole as Ligand for Sensing Guanosine and Mg Ions Through a Fluorescence Turn Off–On Mechanism

Applied Spectroscopy Practica
In this study, a new sensor for the fluorescence detection of guanosine and Mg 2+ ions using a “turn-off–on” mechanism was successfully constructed using 2-mercapto-5-nitrobenzimidazole (MNB) modified bimetallic molybdenum–gold nanoclusters (Mo-AuNCs ...
