| Outline of Final Research Achievements |
In this research, it was investigated a mechanism of escaping system from NK cell attack in sphere-forming prostate cancer cells. Sphere-forming prostate cancer cells (DU145 and PC3) highly expressed NANOG, therefore NANOG-overexpressing DU145 was generated. It was revealed that NANOG-overexpressing DU145 escaped from NK cell attack by ICAM1 downregulation. Moreover, the escaping ability from NK cell attack of sphere-forming DU145 was inhibited by ICAM1 overexpression. Therefore, it was revealed that sphere-forming DU145 had escaping system from NK cell attack by NANOG overexpressing-mediated ICAM1 downregulation.
