Pathological considerations concern mainly the possible participation of an inherited or acquired defect of FAD-linked mitochondrial glycerophosphate dehydrogenase in the impairment of insulin release in non-insulin-dependent diabetes.

|
Well-characterized defects in insulin secretion, most notably a loss of glucose-induced insulin secretion, are found in virtually all forms of NIDDM, as well as in early IDDM.

These include a loss of GLUT2, glycogen accumulation, glucose recycling, abnormal glucokinase or hexokinase, altered mitochondrial glycerol phosphate dehydrogenase (mGPDH) activity, abnormal ion channel function and beta cell degranulation.

Overexpression of mitochondrial FAD-linked glycerol-3-phosphate dehydrogenase does not correct glucose-stimulated insulin secretion from diabetic GK rat pancreatic islets.
|
49 |
9662045
|
In the pancreatic islets of GK rats, the activity of mitochondrial FAD-linked glycerol-3-phosphate dehydrogenase (mGPDH), the key enzyme of the glycerol phosphate shuttle, is decreased and this abnormality may be responsible, at least in part, for impaired glucose-stimulated insulin secretion.
|
50 |
9662045
|
To investigate this possibility, we overexpressed mGPDH in islets isolated from GK rats via recombinant adenovirus-mediated gene transduction, and examined glucose-stimulated insulin secretion.
|
51 |
9662045
|
In islets isolated from diabetic GK rats at 8 to 10 weeks of age, glucose-stimulated insulin secretion was severely impaired, and mGPDH activity was decreased to 79 % of that in non-diabetic Wistar rats.

Basal (3 mmol/l glucose) and glucose-stimulated (20 mmol/l) insulin secretion from the Adex1CAlacZ-infected GK rat islets were, respectively, 4.4 +/- 0.7 and 8.1 +/- 0.7 ng. x islet(-1) x 30 min(-1), and those from mGPDH-overexpressed GK rat islets 4.7 +/- 0.3 and 9.1 +/- 0.8 ng x islet(-1) x 30 min(-1), in contrast to those from the AdexlCAlacZ-infected non-diabetic Wistar rat islets (4.7 +/- 1.6 and 47.6 +/- 11.9 ng x islet(-1) x 30 min(-1)).
|
53 |
9662045

Thus, glucose-stimulated insulin secretion is severely impaired in GK rats even in the stage when mGPDH activity is modestly decreased, and at this stage, overexpression of mGPDH cannot restore glucose-stimulated insulin secretion.

In the 1.0 to 10 microM range, dexamethasone caused a concentration-related decrease in the FAD (flavin adenine dinucleotide)-linked mitochondrial glycerophosphate dehydrogenase (mGDH) mRNA content of the islets, and decreased both the mGDH content of the islets and the catalytic activity of the enzyme in islet homogenates, these effects being often more marked in islets cultured at 16.7 mM, rather than 2.8 mM, D-glucose.
|
85 |
10782559
|
Even after culture in the presence of no more than 10 nM dexamethasone, namely under conditions in which the mGDH mRNA content and activity were both virtually unaffected, the corticosteroid restored the capacity of the beta-cells to display an increase in insulin output in response to a rise in D-glucose concentration in islets first cultured at 2.8 mM D-glucose but suppressed the insulinotropic action of the hexose in islets first cultured at 16.7 mM D-glucose.
