1. Six weeks after the injection of streptozotocin at 125 mg/kg i.p. in the AV line nondiabetic Chinese hamsters, the animals showed hyperglycemia, increased kidney, pancreas and stomach weights and stomach glucagon contents and depletion of insulin and glucagon in the pancreas. 2. Plasma beta-D-galactosidase and N-acetyl-beta-D-glucosaminidase were elevated; whereas alpha-D-glucosidase was decreased and alpha-D-galactosidase remained unchanged in the plasma. 3. In the kidney, streptozotocin-diabetes led to depression of alpha-D-mannosidase, beta-D-fucosidase and N-acetyl-beta-D-glucosaminidase activities in both 12,000 g supernatant and precipitate fractions, decreases in alpha-D-glucosidase in the supernatant only and no change in alpha-L-fucosidase, alpha-D-galactosidase, beta-D-galactosidase and beta-D-glucuronidase. 4. In the liver, significant increases in N-acetyl-beta-D-glucosaminidase, alpha-D-galactosidase, beta-D-galactosidase, beta-D-fucosidase, beta-D-glucosidase and alpha-D-mannosidase were found in either the supernatant or the precipitate fraction of the diabetic animals. The data indicate diabetes-dependent tissue-specific changes in glycohydrolases in the Chinese hamster.

Streptozotocin treatment (125 mg/kg) in the Chinese hamster induced hyperglycaemia, hypoinsulinaemia, hyperglucagonaemia and changes in body, liver, pancreas, stomach, kidney and adipose tissue weights. The pancreatic reserves of insulin and glucagon in the diabetic animals were low, but stomach glucagon high. These animals showed high levels of phosphoenolpyruvate carboxykinase and low levels of glucokinase, hexokinase, isocitrate dehydrogenase and malic enzyme, but normal levels of pyruvate kinase in the liver. Increases in lactate dehydrogenase subunit B and isozymes 2, 3 and 4 were also observed in the liver, but not in the epididymal fat pad, of the diabetic animals. N-Acetyl-beta-D-glucosaminidase was elevated in plasma, liver and heart, but not in the kidney of the treated animals. Renal alpha-galactosidase and beta-glucosidase were depressed, whereas beta-galactosidase and alpha-glucosidase remained essentially normal. These features indicated that there were considerable differences between the biochemical disorders associated with streptozotocin-diabetes in the Chinese hamster and the published observations in the rat.

In the liver of suckling rats, the synthesis of hepatic tyrosine aminotransferase, serine dehydratase, and phosphofructokinase 2 as well as of renal beta-glucosidase is controlled by the circulating concentrations of adrenal and pancreatic hormones. Glucagon is capable of stimulating enzyme synthesis only in the presence of a steroid hormone. Dexamethasone and estradiol have been found to exert a permissive function on the inducibility of the studied enzymes by glucagon. Between the hormones of the adrenal medulla and glucagon antagonistic effects in enzyme induction were observed. Obviously, this antagonism is mediated by the alpha 1-adrenergic signal transferring system. A characteristic age dependence of enzyme induction by dexamethasone has been established. This might be correlated to alterations in the degree of methylation of the respective promoters. The methylation inhibitor 5-azacytidine influences significantly the enzyme induction by glucocorticoid hormones.
