    Kurzfassung: Hepatic steatosis is a widespread metabolic disease characterized by excessive accumulation of triglyceride (TG) in liver. So far, effective approved drugs for hepatic steatosis are still in development, and removing the unnecessary TG from the hepatocytes is an enormous challenge. Here, we explore a promising anti-hepatic steatosis strategy by boosting hepatocellular TG transport using β-alanine–modified gadofullerene (GF-Ala) nanoparticles. We confirm that GF-Ala could reverse hepatic steatosis in oleic acid–induced hepatocytes, fructose-induced mice, and obesity-associated transgenic ob/ob mice. Observably, GF-Ala improves hepatomegaly and hepatic lipid accumulation, reduces lipid peroxidation, and repairs abnormal mitochondria. Of note, we demonstrate that GF-Ala markedly inhibits the posttranslational degradation of apolipoprotein B100 (ApoB100) and boosts hepatocellular TG transport based on their superior antioxidant property. Together, we conclude that GF-Ala could potently ameliorate hepatic TG transport and maintain hepatic metabolic homeostasis without apparent toxicity, being beneficial for treatments of hepatic steatosis and other fatty liver diseases.

    Kurzfassung: Protein function depends critically on intrinsic internal dynamics, which is manifested in distinct ways, such as loop motions that regulate protein recognition and catalysis. Under physiological conditions, dynamic processes occur on a wide range of time scales from subpicoseconds to seconds. Commonly used NMR spin relaxation in solution provides valuable information on very fast and slow motions but is insensitive to the intermediate nanosecond to microsecond range that exceeds the protein tumbling correlation time. Presently, very little is known about the nature and functional role of these motions. It is demonstrated here how transverse spin relaxation becomes exquisitely sensitive to these motions at atomic resolution when studying proteins in the presence of nanoparticles. Application of this novel cross-disciplinary approach reveals large-scale dynamics of loops involved in functionally critical protein-protein interactions and protein-calcium ion recognition that were previously unobservable.
