Outline of Final Research Achievements |
From the above results, it was re-confirmed that the GNAS gene mutation is involved in the carcinogenesis or progression of gastric fundus gland type gastric cancer, and it has been shown for the first time that KRAS and BRAF gene mutations are not related to gastric fundus gland type gastric cancer It was. It is suggested that suppression of Sonic hedgehog signal may be involved in the development or progression of gastric fundus gland type gastric cancer in addition to activation of Wnt / β-catenin signal (particularly methylation is involved in particular) and GNAS gene mutation It was done.
