Protein modification by O-linked N-acetylglucosamine (O-GlcNAcylation) is one of the post transcriptional modifications occurring on cellular proteins. This paper provides a data set relating to the O-GlcNAcylation of cellular proteins detected by RL2 and CTD110.6 antibodies, which are commonly used for detection of protein O-GlcNAcylation, in 2-deoxy-d-glucose (2DG)-treated human teratocarcino...

BACKGROUND Accelerated glucose uptake for anaerobic glycolysis is one of the major metabolic changes found in malignant cells. This property has been exploited for imaging malignancies and as a possible anticancer therapy. The nonmetabolizable glucose analog 2-deoxyglucose (2 DG) interferes with glucose metabolism leading to breast cancer cell death. AIMS To determine whether 2DG can synergiz...

Accelerated senescence (ACS) leading to proliferative arrest is a physiological mechanism of the DNA damage response that occurs during tumor therapy. Our experiment was designed to detect unknown genes that may play important roles in cisplatin-induced senescence and to illustrate the related senescence mechanism. Using 2-dimension electrophoresis (2-DE), we identified 5 protein spots with dif...

Two-dimensional electrophoresis (2-DE) is a powerful and widely used method for the analysis of complex protein mixtures extracted from cells, tissues, or other biological samples. This technique sort’s protein according to two independent properties in two discrete steps: the first-dimension step, isoelectric focusing (IEF), separates proteins according to their isoelectric points (pI); the se...

Two-dimensional gel electrophoresis has been instrumental in the birth and developments of proteomics, although it is no longer the exclusive separation tool used in the field of proteomics. In this review, a historical perspective is made, starting from the days where two-dimensional gels were used and the word proteomics did not even exist. The events that have led to the birth of proteomics ...

• Difference gel electrophoresis (DIGE) is the new gold standard analysing complex protein mixtures in proteomics. It is used for measuring the expression levels of proteins in different mixtures on the same two-dimensional electrophoresis (2-DE) gel. In this paper we review a method for the calibration and normalization of those protein expression measurements. Further we show how to find trea...

Effect of WEB 1881 FU (nebracetam) on hypoxia and ischemia-induced impairment of 2-deoxyglucose (2DG) uptake and CA1 field potentials induced by hypoxia and hypoxia/hypoglycemia (ischemia) in rat brain slices was evaluated and compared to the findings obtained with pentobarbital and idebenone. Hippocampal and cortical slices were exposed to 15-20 min of ischemia, and then these slices were retu...

A condition of reduced responsiveness to hypoglycemia, known as hypoglycemia-associated autonomic failure (HAAF), occurs in diabetic patients in the wake of a prior hypoglycemic episode. This condition suggests that hypoglycemia alters central glucose-sensing mechanisms. This experiment examined the effects of repeated 2-deoxy-D-glucose (2DG)-induced glucoprivation on subsequent 2DG-induced fee...

Neuroblastoma is characterized by a wide range of clinical manifestations and associated with poor prognosis when there is amplification of MYCN oncogene or high expression of Myc oncoproteins. In a previous in vitro study, we found that the glycolytic inhibitor 2-deoxyglucose (2DG) could suppress the growth of neuroblastoma cells, particularly in those with MYCN amplification. In this study, w...
