Outline of Final Research Achievements |
Comprehensive genomic profiling of gastric cancer reveals various mutations and gene expression pattern in each cancer and several new genetic alterations for potentially therapeutic targets. It is important that we have to distinguish “driver mutations” from “passenger mutations” and combinations of genetic variation which contribute to carcinogenesis. We have succeeded in 3D culture, so called “organoid”, of normal gastric epithelial cells from a mouse pyloric-stomach. We could overexpress or silence the genes of interest using lentiviral vector on the organoids and assess for the functions and carcinogenesis by transplanting to nude mice.
