The non-invasive detection of insulinomas remains a diagnostic problem that is not solved by means of somatostatin receptor scintigraphy. We investigated the biokinetics and specificity of uptake and degradation of the incretin hormone glucagon-like peptide-1 (GLP-1) in a rat insulinoma cell line (RINm5F) in order to ascertain whether radiolabelled GLP-1(More)
ATP citrate lyase (EC 4.1.3.8) has been found in crude extracts from endosperm tissue of germinating castor bean and shows its maximum activity in 4- to 5-day-old seedlings. A strict requirement for coenzyme A and adenosine 5'-triphosphate was demonstrated. The pH optimum for the reaction is around 7.5. The unstable enzyme can be stabilized by freezing and(More)
