Zinc finger nuclease mediated knockout of ADP-dependent glucokinase in cancer cell lines: effects on cell survival and mitochondrial oxidative metabolism.
ADPGK knock-out Ramos BL cells display abated in vitro and in vivo tumour aggressiveness, via tumour-macrophage co-culture, migration and Zebrafish xenograft studies. Perturbed glycolysis and visibly reduced markers of Warburg effect in ADPGK knock-out cells, finally leading to apoptosis. Knock-out cells show repression of MYC proto-oncogene, and up to four-fold reduction in accumulated mutations in translocated MYC
upon activation, ADPGK knockout Jurkat T cells display increased cell death and ER stress. The increase in cell death results from a metabolic catastrophe and knockout cells displayed severely disturbed energy metabolism hindering induction of Warburg phenotype
the enzyme plays a critical role in T cell receptor activation-induced remodeling of energy metabolism. The enzyme is part of a glucose sensing system in the ER modulating metabolism via regulation of N- and O-glycosylation
down-regulation of ADPGK or GPD2 abundance inhibits oxidative signal generation and induction of NF-kappaB-dependent gene expression, whereas over-expression of ADPGK potentiates them
T cell activation-induced mitochondrial ROS production and NF-kappaB-driven gene expression depend on activation of ADPGK. ADPGK activation is accompanied by a rapid glucose uptake, downregulation of mitochondrial oxygen consumption, and deviation of glycolysis toward the glycerol-3-phosphate dehydrogenase shuttle
knockout of inc finger nucleases in each H-460 and HCT-11 cells lead to frameshift mutations in all alleles at the target site in exon 1 of ADP-dependent glucokinase ADPGK, and are ADPGK-null by immunoblotting. ADPGK knockout has little or noeffect on cell proliferation, but compromises the ability of H-460 cells to survive siRNA silencing of hexokinase-2 under oxic conditions and anoxia. No such changes are found when ADPGK is knocked out in HCT-116 cells. Knockout of ADPGK in HCT-116 cells causes few changes in global gene expression, while knockout of ADPGK in H-460 cells causes notable up-regulation of mRNAs encoding cell adhesion proteins. No consistent effect on glycolysis under oxic conditions in a variety of media is observed. Oxygen consumption rates are generally lower in the ADPGK knockouts
structures reveal a ribokinase-like tertiary fold similar to archaeal orthologues but with significant differences in some secondary structural elements. Both the unliganded and the AMP-bound ADPGK structures are in the open conformation and reveal the presence of a disulfide bond between conserved cysteines that is positioned at the nucleotide-binding loop. The AMP-bound structure defines the nucleotide-binding site with one of the disulfide bond cysteines coordinating the AMP with its main chain atoms
