| Outline of Final Research Achievements |
Glioblastoma is one of the most malignant tumors in the brain. Necrosis in the tumor tissue is characteristic of glioblastoma. In this study, we examined the functional changes of glioblastoma cells caused by osmotic pressure and nutrient shortage. The expression levels of NFAT5 protein were elevated in hyperosmolarity. In a cell line, colony-forming activity was elevated when the cells were pretreated in hyperosmolarity. The expression levels of GINS proteins were down-regulated in a shortage of glutamine or glucose.
