Description
The aldokatoreductases (AKRs) represent a gene superfamily that code for monomeric, soluble NAD(P)H-dependent oxidoreductases that mediate elimination reactions. AKR1B10, an AKR that functions to eliminate retinals, has been observed to be upregulated in squamous metaplasma and non small cell lung cancer, and has been suggested as a diagnostic marker specific to tobacco-related carcinogenesis. In the context of the link of smoking and lung cancer and the enhanced expression of AKR1B10 expression in lung cancer, we hypothesize that enhanced expression of AKR1B10 may be initiated in healthy smokers, prior to the development of any evidence of lung cancer. For this purpose, expression of AKR1B10 was assessed at the mRNA level using microarrays in the large airway epithelium (21 healthy nonsmokers, 31 health smokers) and small airway epithelium (51 healthy nonsmokers, 58 healthy smokers) obtained by fiberoptic bronchoscopy and brushing, as well as assessment in a subset of this population by TaqMan PCR and in endobronchial biopsies by Western analysis and immunohistochemistry. Compared to healthy nonsmokers, ARK1B10 mRNA levels were markedly upregulated in both the large and small airway epithelium of healthy smokers (large airway microarray p<0.0001, small airway p<0.0001; TaqMan large airway, p<0.02, small airway p<0.01). Consistent with the mRNA data, AKR1B10 protein was significantly upregulated in the airway epithelium of healthy smokers as assessed by Western analysis and by immunohistochemistry, with AKR1B10 expressed in both differentiated and basal cells of the normal epithelium. Finally, cigarette smoke extract mediated up-regulation of AKR1B10 in airway epithelial cells in vitro. Thus, smoking per se mediates up-regulation of AKR1B10 expression in the airway epithelium of healthy smokers with no evidence of lung cancer. In the context of these observations, and the link of AKR1B10 to the metabolism of retinals and to lung cancer, the smoking-induced up-regulation of AKR1B10 may be an early process in the multiple events leading to the develop of lung cancer.

Description
Zinc finger nucleases (ZFN) are powerful tools for editing genes in cells. Here we use ZFNs to interrogate the biological function of human ADPGK, which encodes an ADP-dependent glucokinase (ADPGK), in tumour cell lines. The hypothesis tested is that ADPGK utilises ADP to phosphorylate glucose under conditions where ATP becomes limiting, such as hypoxia. We characterised two ZFN knockout clones in each of two tumour cell lines (H460 and HCT116). All four lines had frameshift mutations in all alleles at the target site in exon 1 of ADPGK, and were ADPGK-null by immunoblotting. ADPGK knockout had little or no effect on cell proliferation, but compromised the ability of H460 cells to survive siRNA silencing of hexokinase-2 under oxic conditions, with clonogenic survival falling from 213% for the parental line to 6.40.8% (p=0.002) and 4.30.8% (p=0.001) for the two knockouts. A similar increased sensitivity to clonogenic cell killing was observed under anoxia. No such changes were found when ADPGK was knocked out in HCT116 cells, for which the parental line was less sensitive than H460 to anoxia and to hexokinase-2 silencing. While knockout of ADPGK in HCT116 cells caused few changes in global gene expression, knockout of ADPGK in H460 cells caused notable up-regulation of mRNAs encoding cell adhesion proteins. Surprisingly, we could discern no effect on glycolysis as measured by glucose consumption or lactate formation under oxic or anoxic conditions, or extracellular acidification rate (Seahorse XF analyser) under oxic conditions in a variety of media. However, oxygen consumption rates were generally lower in the ADPGK knockouts, in some cases markedly so. Collectively, the results demonstrate that ADPGK can contribute to tumour cell survival under conditions of high glycolytic dependence, but the phenotype resulting from knockout of ADPGK is cell line dependent and appears to be unrelated to priming of glycolysis.
