Flow cytometric analysis of glyoxalase-1 expression in human leukocytes.
2011
Altered glyoxalase-1 (GLO-1) activity and expression is associated with the development of late diabetic complications, malignancy and oxidative stress- and aging-related diseases. In the present study, we developed a flow cytometry method for GLO-1 detection in human leukocytes isolated from peripheral blood samples to investigate GLO-1 expression in leukocyte subsets from type 1 and 2 diabetes mellitus patients (n = 11) and healthy subjects (n = 8). The flow cytometry analysis of GLO-1 in leukocytes showed that expression index of GLO-1-positive cells was slightly increased in mononuclear leukocytes from diabetic patients. This result correlated with the increase in GLO-1 activity in the …
Identification of glyoxalase 1 polymorphisms associated with enzyme activity.
2013
The glyoxalase system and its main enzyme, glyoxalase 1 (GLO1), protect cells from advanced glycation end products (AGEs), such as methylglyoxal (MG) and other reactive dicarbonyls, the formation of which is increased in diabetes patients as a result of excessive glycolysis. MG is partly responsible for harmful protein alterations in living cells, notably in neurons, leading to their dysfunction, and recent studies have shown a negative correlation between GLO1 expression and tissue damage. Neuronal dysfunction is a common diabetes complication due to elevated blood sugar levels, leading to high levels of AGEs. The aim of our study was to determine whether single nucleotide polymorphisms (S…
Association of reduced glyoxalase 1 activity and painful peripheral diabetic neuropathy in type 1 and 2 diabetes mellitus patients
2013
Abstract Aims The present study was undertaken to investigate the relationship between glyoxalase 1 (Glo1) enzyme activity and painful diabetic neuropathy (DN) in patients with diabetes mellitus. Methods Glo1 activity and biochemical markers were determined in blood samples from 108 patients with type 1 diabetes, 109 patients with type 2 diabetes, and 132 individuals without diabetes as a control. Painful and painless peripheral DN was assessed and multivariate regression analysis was used to determine independent association of Glo1 activity with occurrence of painful DN. Results In patients with type 1 and type 2 diabetes mellitus and painful DN compared to patients with painless DN, Glo1…
