Genetically encoded fluorescent sensors for intracellular NADH detection.
We have developed genetically encoded fluorescent sensors for reduced nicotinamide adenine dinucleotide (NADH), which manifest a large change in fluorescence upon NADH binding. We demonstrate the utility of these sensors in mammalian cells by monitoring the dynamic changes in NADH levels in subcellular organelles as affected by NADH transport, glucose metabolism, electron transport chain functi...
متن کاملA novel role for yeast casein kinases in glucose sensing and signaling
Yeasts have sophisticated signaling pathways for sensing glucose, their preferred carbon source, to regulate its uptake and metabolism. One of these is the sensor/receptor-repressor (SRR) pathway, which detects extracellular glucose and transmits an intracellular signal that induces expression of HXT genes. The yeast casein kinases (Ycks) are key players in this pathway. Our model of the SRR pa...
متن کاملSimultaneous NMR microdialysis study of brain glucose metabolism in relation to fasting or exercise in the rat.
To study the impact of exercise or fasting and of subsequent glucose supplementation on glucose metabolism in rats, a spectrophotometric method was used to determine peripheral blood glucose; a technique associating (1)H-NMR spectroscopy and cortical microdialysis was also used to observe intra- plus extracellular and extracellular brain glucose variations, respectively. Compared with control a...
متن کاملFluorescence lifetime imaging microscopy of intracellular glucose dynamics.
BACKGROUND One of the major hurdles in studying diabetes pathophysiology is the lack of adequate methodology that allows for direct and real-time determination of glucose transport and metabolism in cells and tissues. In this article, we present a new methodology that adopts frequency-domain fluorescence lifetime imaging microscopy (FD-FLIM) to visualize and quantify the dynamics of intracellul...
متن کاملKinetics of glucose transport and sequestration in lactating bovine mammary glands measured in vivo with a paired indicator/nutrient dilution technique.
To quantify kinetics of mammary glucose utilization in vivo, 24 paired glucose and extracellular indicator (p-aminohippuric acid) dilution curves across intact bovine mammary glands were obtained after bolus injections into the external iliac artery. Dilution curves were analyzed using a compartmental capillary, convolution integration model. Four candidate submodels of glucose transport and me...
