Pancreatic ductal adenocarcinoma (PanCa) is an extremely lethal disease characterized by mutations of p53 in up to 70% of cases. Our previous studies have confirmed that hyperglycemia may be the first clinical manifestation for the early diagnosis of PanCa. In this article, we showed that targeted knockdown of TG2 or p53 in tumor cells led to decreased cell survival in response to glucose depri...
in this study, the effect of short-terms starvation (0, 2, 4 and 8 days) on plasma cortisol, glucose, triglyceride and cholesterol levels and also hepatosomatic index in siberian sturgeon, acipenser baerii, was investigated. after acclimation to experimental conditions for 10 days using formulated diet, 180 juvenile siberian sturgeons (mean weight ? s.e.=19.3?0.4, n=15) were randomly distribute...
Metabolic stress occurs frequently in tumors and in normal tissues undergoing transient ischemia. Nutrient deprivation triggers, among many potential cell death-inducing pathways, an endoplasmic reticulum (ER) stress response with the induction of the integrated stress response transcription factor ATF4. However, how this results in cell death remains unknown. Here we show that glucose deprivat...
The present paper evaluates the contributions of glucose and its metabolites to the post-translational regulation of hexose transport and GLUT-1 content in murine fibroblasts. The effects of 3-O-methylglucose, a nearly non-metabolizable glucose analogue, on 2-deoxyglucose-uptake, cell-surface expression and content of GLUT-1, glucose 6-phosphate levels, and phosphoglucose isomerase (PGI) and he...
Glucose is considered the primary energy source for all cells, and some cancers are addicted to glucose. Here, we investigated the functional consequences of chronic glucose deprivation in serous ovarian cancer cells. We found that cells resistant to glucose starvation (glucose-restricted cells) demonstrated increased metabolic plasticity that was dependent on NNMT (Nicotinamide N-methyltransfe...
