Copper is a required metal nutrient for life, but global or local alterations in its homeostasis are linked to diseases spanning genetic and metabolic disorders to cancer and neurodegeneration. Technologies that enable longitudinal in vivo monitoring of dynamic copper pools can help meet the need to study the complex interplay between copper status, health, and disease in the same living organism over time. Here, we present the synthesis, characterization, and in vivo imaging applications of Copper-Caged Luciferin-1 (CCL-1), a bioluminescent reporter for tissue-specific copper visualization in living animals...

Elevated lipogenesis is a common characteristic of cancer and metabolic diseases. Sterol regulatory element-binding proteins (SREBPs), a family of membrane-bound transcription factors controlling the expression of genes important for the synthesis of cholesterol, fatty acids and phospholipids, are frequently upregulated in these diseases. In the process of SREBP nuclear translocation, SREBP-cleavage activating protein (SCAP) plays a central role in the trafficking of SREBP from the endoplasmic reticulum (ER) to the Golgi and in subsequent proteolysis activation...

BACKGROUND The risk of liver cirrhosis is higher among individuals with diabetes mellitus, and a cirrhotic patient with diabetes may have a poorer prognosis after liver transplantation compared to a patient without diabetes. Thus, we evaluated whether fasting plasma glucose prior to receiving a liver transplant was a prognostic factor for post-transplant survival. MATERIAL AND METHODS Ninety-one patients received a living donor liver transplant between November 2005 and December 2012. Patients were considered diabetic if they were prescribed diabetes medications or had impaired glucose tolerance as measured by an oral glucose tolerance test...

Trehalose-6-phosphate (T6P) is an important signaling metabolite involved in plant growth control that inhibits the sucrose nonfermenting-1-related protein kinase 1 (SnRK1), a key regulator of energy and carbon metabolism in plants. The quantification of T6P in plant tissues is fundamental to improve our understanding of sugar signaling and the links between plant growth and development in response to stress conditions. However, the almost undetectable levels of T6P together with the complex plant matrix and the presence of T6P isomers such as sucrose-6-phosphate (S6P), makes the detection of this metabolite challenging...

BACKGROUND: Medium-chain acyl-CoA dehydrogenase deficiency is the most common genetically determined disorder of mitochondrial fatty acid oxidation. Decompensation can result in hypoglycemia, seizures, coma, and death but may be prevented by ensuring glycogen stores do not become depleted. Perioperative care is of interest as surgery, fasting, and infection may all trigger decompensation and the safety of anesthetic agents has been questioned. Current guidelines from the British Inherited Metabolic Disease Group advise on administering fluid containing 10% glucose during the perioperative period...
