Project description:Analysis of Huh-7 hepatocarcinoma cell line depleted of NDRG3 or HIF-1α under hypoxic condition. HIF-1α and NDRG3 have distinct functions in hypoxia responses. Results provide insight into molecular basis of HIF-independent signaling in the development and progression of hypoxic tumors Gene expression profiles of Huh-7 cells stably expressing NDRG3-shRNA or HIF-1α-shRNA under normoxia were compared to gene expression profiles of Huh-7 stable cells under hypoxia for 6, 12 and 24 hours.

Project description:We perfomed RNA-sequencing for searching upstream regulators regulated by NDRG3 gene. RNA profiles of each cell line were used to figure out Differentially Expressed Genes (DEG) by NDRG3 depletion, we found NDRG3-related upstream regulators by applicating DEG to Ingenuity Pathway Analysis (IPA).

Project description:Rapidly proliferating tumors are exposed to a hypoxic microenvironment due to their density, high metabolic consumption, and interruptions in blood flow due to immature angiogenesis. Cellular responses to hypoxia promote highly malignant and metastatic behavior, as well as a chemotherapy-resistant state. In order to better understand the complex relationships between hypoxic adaptations and cancer progression, we studied the dynamic proteome responses of glioblastoma cells exposed to hypoxia via an innovative approach: quantification of newly synthesized proteins using heavy stable-isotope arginine labeling combined with accurate assessment of cell replication by quantification of the light/heavy arginine ratio of peptides in histone H4. We found that hypoxia affects cancer cells in multiple intertwined ways: inflammation, typically with over-expressed glucose transporter (GLUT1), DUSP4/ MKP2, and RelA proteins; a metabolic adaptation with overexpression of all glycolytic pathway enzymes for pyruvate/lactate synthesis; and the EMT (epithelial-mesenchymal transition) and cancer stem cell (CSC) renewal with characteristic morphological changes and mesenchymal/CSC protein expression profiles. For the first time, we identified the vitamin B12 transporter protein TCN2, which is essential for one-carbon metabolism, as being significantly downregulated. Further, we found, by knockdown and overexpression experiments, that TCN2 plays an important role in controlling cancer cell transformation towards the highly aggressive mesenchymal/CSC stage; low expression of TCN2 has an effect similar to hypoxia, while high expression of TCN2 can reverse it. We conclude that hypoxia induces sequential metabolic responses of one-carbon metabolism in tumor cells.
