Abstract Cancer cells display an altered metabolism with an increased glycolysis and a lower respiration rate, leading to an increased glucose uptake. These particularities provide therapeutic opportunities and anti-cancer strategies targeting glycolysis through metaBolic inhiBitors have been put forth. One of these inhibitors, the glucose analogue 2-deoxyglucose (2DG), is imported into cells and phosphorylated into 2DG-6-phosphate, a toxic by-product that accumulates in cells and inhibits glycolysis. Recent data suggest that 2DG has additional effects in the cell, and resistance to 2DG has also Been oBserved.
