Influence of Dietary Fat Level on the Enzymatic and Lipogenic Adaptations in Adipose Tissue of Meal-fed Rats Article (PDF Available) in Journal of Nutrition 91(2) March with 25 Reads.   A new and highly sensitive fluorimetric assay for hexokinase (HK) isoenzymes which requires only 5 μg. of tissue protein is described. This assay has been used to examine the alterations in the HK isoenzymes of rat skeletal muscle and adipose tissue under a variety of physiologic conditions. In both tissues, HK-II declined progressively with increasing age, reaching plateau levels in animals Cited by:

Four distinct isozymes of hexokinase were separated by ion exchange chromatography (González et al., ) or electrophoresis (Katzen and Schimke, ) of extracts from various mammalian lly these are referred to as the Type I, Type II, Type III and Type IV isozymes, with the latter commonly called `glucokinase'.Cited by: Leveille GA.

  The effects of dexamethasone and growth hormone on hexokinase (HK) isoenzymes and glucose utilization were studied in adipose tissue from young rats. Dexamethasone ( mg./kg. twice a day) caused hyperinsulinemia with normal blood glucose and marked diminution of adipose tissue HK-II after twenty-four and forty-eight hours. HK-I activity was reduced after twenty-four hours Cited by:   Detection of Type III Hexokinase in Rat Tissue Extracts by Immunoblotting Freshly harvested rat tissues were minced on ice and homogenized in a buffer (1 ml buffer/ mg of tissue) consisting of 50 m m sodium phosphate, pH , 10 m m Glc, 10 m m thioglycerol, and % (v/v) Triton X, using a tightly fitting glass tissue homogenizer.

Because the isozymes have different kinetic features, this has permitted them to become optimally adapted to the needs of the specific tissue in which they are the major isozyme. Isozymes of mammalian hexokinase Four distinct isozymes of hexokinase were separated by ion exchange chromatography (González et al., ) or electrophoresis (Katzen and Schimke, ) of extracts from various mammalian tissues.
