Lipolysis in rat adipocytes during recovery from lactation. Response to noradrenaline and adenosine

The replenishment of lipid reserves of adipocytes following the removal of litters from lactating rats is associated with a 3-fold decrease in both the response of lipolysis to noradrenaline and the maximum rate of lipolysis (measured in the presence of noradrenaline plus adenosine deaminase); these adaptations do not appear to result from the changes in serum prolactin and insulin concentrations that occur on litter removal.
