The video demonstrates a technique for measuring glucose uptake in Drosophila larval motor neurons using a fluorescence resonance energy transfer (FRET)-based intracellular glucose sensor. After dissecting the larvae to expose the ventral nerve cord, the motor neurons are visualized through the fluorescence emitted by the sensor's donor fluorophore. When stimulated with glucose, FRET between the sensor's donor and acceptor fluorophores triggers the emission of fluorescence from the acceptor,...

In this video, we demonstrate an ex vivo technique to measure extracellular glucose analog depletion in harvested mouse organs. It involves incubating the mouse tissue in a solution containing fluorescently-labeled deoxyglucose, which is taken up by the cells. The glucose analog uptake can be indirectly determined by measuring the fluorescence of the incubated medium.

FAQs
In skeletal muscle and adipose tissue, insulin increases glucose entry by promoting GLUT4 transporters to the cell surface. This relocation changes how readily these cells access circulating glucose after a meal. The response matters because impaired insulin signaling can alter glucose distribution, making GLUT4 movement a key mechanism studied in metabolic disease.
The liver, brain, and other tissues do not follow the same transporter pattern as muscle and adipose tissue. Their glucose entry depends on different transporters and regulatory mechanisms, allowing uptake to reflect distinct physiological requirements. Comparing these tissues prevents glucose handling from being treated as uniform and clarifies how the body maintains energy balance.
Glucose distribution after a meal reflects the interaction between circulating glucose, hormonal signals, and tissue-specific transporters. Insulin-sensitive tissues can change their surface availability of GLUT4, whereas other tissues rely on different regulatory systems. This coordination determines whether glucose is directed toward immediate energy production, storage, or biosynthetic activity in particular tissues.
GLUT4 trafficking provides a direct way to examine how insulin controls glucose entry into skeletal muscle and adipose tissue. If this regulated movement is disrupted, researchers can investigate how tissue glucose handling contributes to broader metabolic imbalance. Consequently, GLUT4 behavior is relevant to studies of insulin resistance, diabetes, and related metabolic disease.
Researchers measure tissue-specific glucose uptake by examining how glucose distribution differs among organs and tissues under defined physiological conditions, including the period after a meal. These measurements reveal whether particular tissues are receiving, using, or storing glucose. The resulting patterns help connect transporter and hormonal activity with whole-body energy balance and metabolic disease.
Comparing uptake across tissues shows that glucose handling depends on local transporter expression and regulatory control rather than on blood glucose alone. Such comparisons can identify distinctive patterns in skeletal muscle, adipose tissue, liver, and brain. They therefore help explain organ-specific contributions to energy balance and provide context for interpreting metabolic abnormalities.
In medicine, tissue-specific glucose uptake connects cellular glucose handling with insulin resistance, diabetes, and metabolic disease. Mapping how different tissues respond can support imaging-based diagnostics that distinguish distribution patterns rather than relying only on circulating glucose. The same information may guide targeted therapies designed around the regulatory mechanisms of particular tissues.
