| 1 | Unloading performances and stabilizing practices for columnar jointed basalt:A case study of Baihetan hydropower station显示文摘The columnar jointed rock mass(CJR), composed of polygonal cross-sectional columns cut by several groups of joints in various directions, was exposed during the excavations of the Baihetan hydropower station, China. In order to investigate the unloading performances and the stability conditions during excavation of the columns, an experimental field study was performed. Firstly, on-site investigations indicated that the geotechnical problems, including rock relaxation, cracking and collapse, were the most prominent for the CJR Class I that contains intensive joint network and the smallest column sizes.Comprehensive field tests, including deformation measurement by multi-point extensometers, ultrasonic wave testing, borehole television observation and stress monitoring of rock anchors, revealed that the time-dependent relaxation of the CJRs was marked. The practical excavation experiences for the Baihetan columnar jointed rock masses, such as blasting scheme, supporting time of shotcrete and rock bolts, were presented in the excavations of the diversion tunnels. These detailed investigations and practical construction experiences can provide helpful information for similar geotechnical works in jointed rock mass. | Qixiang Fan Xiating Feng Wenlin Weng Yilin Fan Quan Jiang | 2017 | Journal of Rock Mechanics and Geotechnical Engineering2017，9，6： | 4 |
| 2 | ZBTB7A governs 2-DG-inhibited glycolysis by regulating GLUT1 in nasopharyngeal carcinoma显示文摘Our previous studies suggested a potential interaction between the POK erythroid myeloid ontogenic factor ZBTB7A and glucose transporter 1(GLUT1)in nasopharyngeal carcinoma(NPC).This study was designed to confirm the interaction and further evaluate the precise mechanism by which ZBTB7A and GLUT1 regulate NPC development.The binding sites between ZBTB7A and the promoter of GLUT1 were predicted by bioinformatics.Gene expression was measured by quantitative real-time polymerase chain reaction(qPCR),western blotting,and immunohistochemistry.The activities of key glycolysis enzymes,including hexokinase(HK),pyruvate kinase(PK),lactate dehydrogenase(LDH),and lactate,were detected using specific enzyme-linked immunosorbent assay kits.The connection between ZBTB7A and GLUT1 was analyzed by dual-luciferase reporter assay and chromatin immunoprecipitation-qPCR.The vitality,proliferation,and tumorigenicity of the cells expressing different levels of ZBTB7A were tested by adding the glycolysis inhibitor 2-deoxy-D-glucose(2-DG),followed by MTT,colorimetric focus forming,and xenograft assays,respectively.Our results showed that high expression of GLUT1 was associated with late-stage NPC.After constructing stably transfected cells with lentiviruses,ZBTB7A was effectively knocked down in 5-8F cells(RNAi-5-8F)and overexpressed in 6-10B cells(ZBTB7A-6-10B).The up-or downregulation of GLUT1 secondary to ZBTB7A changes was also limited.The vitality and proliferation of the cells expressing low ZBTB7A were notably blocked by 2-DG.The cells expressing high ZBTB7A were not very sensitive to 2-DG.The growth of RNAi-5-8F xenografts was strongly suppressed by 2-DG.The activities of HK,PK,and LDH were suppressed by 2-DG in the cells expressing low ZBTB7A.RNAi-5-8F cells had the lowest 2-DG-induced lactate production.ZBTB7A directly suppressed the promoter region of GLUT1 to regulate GLUT1 expression.Thus,ZBTB7A controls the 2-DG-induced inhibition of glycolysis by affecting GLUT1. | FEI LIU JIAZHANG WEI JIAO LAN YONGLI WANG JIANXIANG YE CHENG SU MINGZHENG MO FENGZHU TANG BING LI MIN LI WEIMING DENG LINSONG YE WENLIN HUANG JINGJIN WENG WEI JIAO SHENHONG QU | 2022 | BIOCELL2022，46，12： | 0 |
