    Abstract 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.… More >

    Abstract LncRNAs and metabolism represents two factors involved in cancer initiation and progression. However, the interaction between lncRNAs and metabolism remains to be fully explored. In this study, lncRNA FEZF1-AS1 (FEZF1- AS1) was found upregulated in colon cancer after screening all the lncRNAs of colon cancer tissues deposited in TCGA, the result of which was further confirmed by RNAscope staining on a colon tissue chip. The results obtained using FEZF1- AS1 knockout colon cancer cells (SW480 KO and HCT-116 KO) constructed using CRISPR/Cas9 system confirmed the proliferation, invasion, and migration-promoting function of FEZF1-AS1 in vitro. Mechanistically, FEZF1-AS1 associated with the mitochondrial… More >

    Silencing of NADPH Oxidase 4 Attenuates Hypoxia Resistance in Neuroblastoma Cells SH-SY5Y by Inhibiting PI3K/Akt-Dependent Glycolysis

    Ting Yu*1, Lei Li†1, Wenyan Liu*, Bailiu Ya*, Hongju Cheng*, Qing Xin*

    Oncology Research, Vol.27, No.5, pp. 525-532, 2019, DOI:10.3727/096504018X15179668157803

    Abstract Hypoxia-induced chemoresistance is a major obstacle in the development of effective cancer therapy. In our study, the reversal abilities of NADPH oxidase 4 (NOX4) silence on hypoxia resistance and the potential mechanism were investigated. Our data showed that the expression of NOX4 was upregulated in human neuroblastoma cells SH-SY5Y under hypoxia condition time dependently. Knockdown of NOX4 expression by siRNA inhibited glycolysis induced by hypoxia through decreasing the expression of glycolysis-related proteins (HIF-1 , LDHA, and PDK1), decreasing glucose uptake, lactate production, and ROS production, while increasing mitochondria membrane potential. Moreover, NOX4 silence inhibited cell growth under hypoxia condition through… More >

    SUFANG ZHANG1,2,#, XIANG LV1,#, LI LI3,#, YINGBIN LUO1, HUINAN XIANG1, LIXIN WANG2,*, YAN LI1,*

    BIOCELL, Vol.45, No.1, pp. 167-175, 2021, DOI:10.32604/biocell.2021.013636

    Abstract Chemotherapy is widely used for non-small cell lung cancer (NSCLC) patients at a late stage; however, NSCLC patients often acquire resistance to chemotherapeutic drugs, thus limiting the therapy efficacy. Melittin, a major component of bee venom, possesses anti-tumor activity in various cancer cells. Here, we examined the effects of melittin on A549/DDP cisplatin-resistant lung adenocarcinoma cells and xenografts formed from this cell line and investigated the possible target of melittin. Treatment with melittin resulted in the induction of cell apoptosis, glycolysis inhibition, and reduction of phosphorylated AKT (p-AKT) in A549/DDP cells. We also identified that tripartite motif-containing 8 (TRIM8) was… More >

    ABSTRACT

    Matrix Stiffness Promotes Hepatoma Cell Glycolysis and Migration Through YAP-Mediated Mechanotransduction

    Qiuping Liu1, Guanbin Song1,*

    Molecular & Cellular Biomechanics, Vol.16, Suppl.2, pp. 127-127, 2019, DOI:10.32604/mcb.2019.07105

    Abstract Hepatocellular carcinoma (HCC) is one of the most prevalent and lethal malignancies worldwide. Increased matrix stiffness of extracellular matrix (ECM) is commonly associated with HCC. During tumour formation and expansion, increasing glucose metabolism is necessary for unrestricted growth of tumour cells. Yet, the correlation between matrix stiffness and glucose metabolism in the development of HCC remains unknown. In this study, we aim to investigate the effect of matrix stiffness on glucose metabolism and migration of MHCC97L and HepG2 hepatoma cells, and explore the mechanotransduction involved in this process. Polyacrylamide hydrogels with stiffness gradients of 6, 25, 54 kPa were produced… More >
