title: Hormonal regulation of fructose 2,6-bisphosphate levels in epididymal adipose tissue of rat.
abstract: The participation of fructose 2,6-bisphosphate on glycolysis stimulated by insulin and adrenaline in incubated white adipose tissue of rat was investigated. Adrenaline addition to incubated fat-pads strongly decreased the intracellular levels of fructose 2,6-bisphosphate. When the tissue was preincubated with glucose, the presence of insulin in the incubation medium increased fructose 2,6-bisphosphate levels 2-fold. These variations were related to changes in the substrates, ATP and fructose 6-phosphate. It therefore appears that fructose 2,6-bisphosphate may be involved in the control of insulin-induced glycolysis, but it does not seem to play a role in the stimulation of glucolysis by adrenaline.
