An evolutionarily conserved family of phosphatases enables cells to resist the toxic metabolic effects of 2-deoxyglucose. Resisting a metabolic poison Once imported into cells and phosphorylated, the glucose analog 2-deoxyglucose (2DG) inhibits glycolysis, leading to the proposal of using 2DG as a cancer treatment. Using yeast as a model, Defenouillère et al. investigated how cells become resistant to 2DG. Exposure to 2DG activated several signaling pathways that resulted in the increased… 
2-deoxyglucose inhibits yeast AMPK signaling and triggers glucose transporter endocytosis, potentiating the drug toxicity
It is shown that 2DG-induced endocytosis is detrimental to cells, and the lack of Rod1 counteracts this process by stabilizing glucose transporters at the plasma membrane, and a remarkable strategy to bypass 2DDG toxicity involving glucose transporter regulation is highlighted.
Novel mutation in hexokinase 2 confers resistance to 2-deoxyglucose by altering protein dynamics
A genetic screen in Saccharomyces cerevisiae generated a novel spontaneous mutation in hexokinase-2, hxk2G238V, that confers resistance to the toxic glucose analog 2-deoxyglucose (2DG), providing insights that may apply to cancer biology and drug resistance.
Spontaneous mutations that confer resistance to 2-deoxyglucose act through Hxk2 and Snf1 pathways to regulate gene expression and HXT endocytosis
Bakers’ yeast is used as a model organism to better understand the mechanism of toxicity and acquisition of resistance to 2-deoxyglucose and it is concluded that Snf1 kinase-mediated regulation of the endocytosis of the hexose transporters and regulation of DOG2 expression are important mechanisms for resistance to this glucose analog.
‘Sugarcoating’ 2-deoxyglucose: mechanisms that suppress its toxic effects
The cellular and metabolic pathways that play a role in 2-deoxyglucose sensitivity are reviewed and how the modifications to these pathways result in acquisition of 2- deoxyglUCose resistance are discussed.
Drug resistance in diploid yeast is acquired through dominant alleles, haploinsufficiency, gene duplication and aneuploidy
The frequent use of aneuploidy as a genetic strategy for drug resistance in diploid yeast and human tumors may be in part due to its potential for reversibility when selection pressure shifts.
Glycolysis inhibition and apoptosis induction in human prostate cancer cells by FV-429-mediated regulation of AR-AKT-HK2 signaling network.
2-Deoxy-d-glucose: from diagnostics to therapeutics
The diagnostic and therapeutic potentials of 2-deoxy-glucose are reviewed with special emphasis on to its implications in SARS-CoV-2.
Phosphorylation of the GARP Subunit Vps53 by Snf1 Leads to the Formation of a Golgi – Mitochondria Contact Site (GoMiCS) in Yeast
The GARP subunit Vps53 is both an in vivo and in vitro target of Snf1 and phosphorylation depends on the nature and quantity of the available carbon source, which results in altered mitochondrial dynamics and the formation of a previously unknown contact site between the Golgi apparatus and mitochondria, termed GoMiCS.
2-Deoxy Glucose: A Ray of Hope for Treatment of Covid-19
2-Deoxy-D-glucose, mimic of glucose having deoxygenated carbon at second position i.e. hydroxyl group is replaced by hydrogen, due to which 2-DG cannot undergo further glycolysis. It inhibits the


Genetic Analysis of Resistance and Sensitivity to 2-Deoxyglucose in Saccharomyces cerevisiae
It is shown that the relative toxicity of 2-deoxyglucose is carbon source dependent, as is the resistance conferred by gene deletions, and that these newly identified genes do not in fact confer significant resistance to 2- deoxyglUCose.
A catabolic block does not sufficiently explain how 2-deoxy-d-glucose inhibits cell growth
It is reported that separating glycolysis and the pentose phosphate pathway highly increases cellular tolerance to 2-DG, indicating that 2- DG does not block cell growth solely by preventing glucose catabolism and processes beyond the metabolic block are essential for the biological properties of 2-G.
Novel actions of 2-deoxy-D-glucose: protection against Shiga toxins and changes in cellular lipids.
The data indicate that the 2DG-induced protection against Stx is independent of inhibition of glycolysis or N-glycosylation, but rather mediated via the depletion of Ca(2+) from cellular reservoirs by2DG.
Identification of Mitogen-Activated Protein Kinase Signaling Pathways That Confer Resistance to Endoplasmic Reticulum Stress in Saccharomyces cerevisiae
The feasibility of using the yeast deletion pool to identify relevant mammalian orthologues of the UPR is shown, and it is proposed that the SLT2 MAPK pathway is an important cell survival signaling pathway during ER stress.
Cooperative Regulation of DOG2, Encoding 2-Deoxyglucose-6-Phosphate Phosphatase, by Snf1 Kinase and the High-Osmolarity Glycerol–Mitogen-Activated Protein Kinase Cascade in Stress Responses of Saccharomyces cerevisiae
The results suggest that Snf1p kinase and the high-osmolarity glycerol-mitogen-activated protein kinase cascade are likely to be involved in the signaling pathway of oxidative stress and osmotic stress in regulation of DOG2.
