Summary

The influence of glucose and insulin on pentose phosphate shunt enzymes and malic enzyme activity in cultured human endothelial cells has been investigated. Glucose-6-phosphate dehydrogenase, 6-phosphogluconate dehydrogenase and malic enzyme were present in endothelial cells. Enzyme activities were not altered either by 20 mM glucose or 10-8 M insulin after 3, 6 and 12 hour incubations respectively.

Neither increased glucose nor increased insulin alter the activity of the pentose phosphate shunt. As a consequence fatty acid and cholesterol synthesis in the endothelial cell is unlikely to be altered in the presence of increased glucose or increased insulin.
