Abstract
Glycerokinase activity in isolated fat cells was elevated in both Ob/Ob and Db/Db mice in comparison to their lean controls and this elevation was associated with obesity, hyperinsulinemia and hyperglycemia. In the other forms of acquired and genetic obesity in the rats and mice studied (also associated with hyperinsulinemia), adipose tissue glycerokinase activity was not elevated in comparison to lean control groups when expressed on a mg protein basis. It is concluded that the elevated glycerokinase activity is not due to the specific Db or Ob mutation, but is secondary to the obesity and hyperinsulinemia interacting with the similar genetic background in the C57BL/KsJ and the C57BL/6J mouse strains.
