We observed the effect of 2-deoxy-D-glucose (2-DG) on the brain tissue in rat cerebral ischemia-reperfusion (I/R) and explored its mechanism. After observing the effect of 2-DG on endoplasmic reticulum stress (ERS), rats were randomly divided into sham-operation group, I/R group and I/R+2-DG group (each group with 60 rats). I/R models were prepared by middle cerebral artery occlusion. In I/R+2-DG group, each rat was given intraperitoneal 2-DG of 100 mg/kg once a day for 7 days before brain ischemia. According to different time points (3h, 6h, 12h, 24h and 48h) after I/R, each group was divided into 5 subgroups (each subgroup with 12 rats). Nerve cell apoptosis, and the expressions of mRNA and protein of glucose regulated protein 78 (GRP78), cleaved-caspase-9 and cleaved-caspase-3 were determined with TUNEL, Western blotting and RT-PCR, respectively, in rat cerebral hippocampal CA1 area at each time point. TUNEL-positive cells were significantly less in I/R+2-DG group than in I/R group at each time point (all P<0.

PURPOSE: To investigate the association between 18fluorine-2-deoxy-D-glucose positron emission tomography-computed tomography (18F-FDG PET/CT) parameters, serum carcinoembryonic antigen (CEA), and tumor response in patients with rectal cancer receiving neoadjuvant chemoradiotherapy (nCRT).
3.Cyanine-based 1-amino-1-deoxyglucose as fluorescent probes for glucose transporter mediated bioimaging.
Xu H1, Liu X1, Yang J2, Liu R1, Li T1, Shi Y1, Zhao H1, Gao Q3. Biochem Biophys Res Commun. 2016 Mar 28. pii: S0006-291X(16)30446-6. doi: 10.1016/j.bbrc.2016.03.133. [Epub ahead of print]
Two novel cyanine-based 1-amino-1-deoxy-β-glucose conjugates (Glu-1N-Cy3 and Glu-1N-Cy5) were designed, synthesized and their fluorescence characteristics were studied. Both Glu-1N-Cy3 and Glu-1N-Cy5 accumulate in living HT29 human colon cancer cells, which overexpress glucose transporters (GLUTs). The cellular uptake of the bioprobes was inhibited by natural GLUT substrate d-glucose and 2-deoxy-d-glucose. The GLUT specificity of the probes was validated with quercetin, which is both a permeant substrate via GLUTs and a high-affinity inhibitor of GLUT-mediated glucose transport. Competitive fluorometric assay for GLUT substrate cell uptake revealed that Glu-1N-Cy3 and Glu-1N-Cy5 are 5 and 10 times more sensitive than 2-NBDG, a leading fluorescent glucose bioprobe. This study provides fundamental data supporting the potential of these two conjugates as new powerful tools for GLUT-mediated theranostics, in vitro and in vivo molecular bioimaging and drug R&D.

Tumor, lymph node, and metastasis (TNM) classification of lung cancer is typically performed with the TNM staging system, as recommended by the Union Internationale Contre le Cancer (UICC), the American Joint Committee on Cancer (AJCC), and the International Association for the Study of Lung Cancer (IASLC). Radiologic examinations for TNM staging of lung cancer patients include computed tomography (CT), magnetic resonance imaging (MRI), positron emission tomography with 2-[fluorine-18] fluoro-2-deoxy-D-glucose (FDG-PET), and FDG-PET combined with CT (FDG-PET/CT) and are used for pretherapeutic assessments. Recent technical advances in MR systems, application of fast and parallel imaging and/or introduction of new MR techniques, and utilization of contrast media have markedly improved the diagnostic utility of MRI in this setting. In addition, FDG-PET can be combined or fused with MRI (PET/MRI) for clinical practice. This review article will focus on these recent advances in MRI as well as on PET/MRI for lung cancer staging, in addition to a discussion of their potential and limitations for routine clinical practice in comparison with other modalities such as CT, FDG-PET, and PET/CT.
