Hexokinase II integrates energy metabolism and cellular protection: Akting on mitochondria and TORCing to autophagy.
San Diego, United States. In Cell Death Differ, 17 Nov 2014
This review summarizes recent advances in understanding the protective role of HK-II, controlling cellular growth, preventing mitochondrial death pathway and enhancing autophagy, with a particular focus on the interaction between HK-II and Akt/mTOR pathway to integrate metabolic status with the control of cell survival.Cell Death and Differentiation advance online publication, 17 October 2014; doi:10.1038/cdd.2014.173.
mTOR- and HIF-1α-mediated aerobic glycolysis as metabolic basis for trained immunity.
Nijmegen, Netherlands. In Science, 26 Oct 2014
Trained monocytes display high glucose consumption, high lactate production, and a high ratio of nicotinamide adenine dinucleotide (NAD(+)) to its reduced form (NADH), reflecting a shift in metabolism with an increase in glycolysis dependent on the activation of mammalian target of rapamycin (mTOR) through a dectin-1-Akt-HIF-1α (hypoxia-inducible factor-1α) pathway.

Santiago, Chile. In Biomed Res Int, Dec 2013
Specifically, tumor suppressor genes that negatively regulate mTOR, such as PTEN, AMPK, LKB1, and TSC1/2 stimulate autophagy while, conversely, oncogenes that activate mTOR, such as class I PI3K, Ras, Rheb, and AKT, inhibit autophagy, suggesting that autophagy is a tumor suppressor mechanism.
