In dogs, hyperadrenocorticism (HAC) is associated with insulin resistance and diabetes does progress with HAC. There are significant differences in the transcriptomic and proteomic patterns of activated T cells, which parallel the findings in muscle tissues. The aim of this study was to assess how glucocorticoids affect intracellular metabolites in canine peripheral blood mononuclear cells (CnPBMCs) using dexamethasone.
A total of 96 metabolites were identified by capillary electrophoresis time-of-flight mass spectrometry (CE-TOFMS). After incubation with dexamethasone, the metabolites glucose 1-phosphate, glucose 6-phosphate, fructose 6-phosphate, sedoheptulose 7-phosphate and acetyl-CoA were significantly increased. However, ATP, CTP, dATP, pyruvic acid and NADP(+) were significantly decreased. These results show that a glucocorticoid reduces the catabolic reaction of glucose and accordingly decreases the glucose requirements of CnPBMCs. (C) 2015 Elsevier Ltd. All rights reserved.
