Adherent c.1380delA CDH1 SB.mhdgc-1 cells, derived from a patient with hereditary diffuse gastric cancer due a germline CDH1 mutation, and adherent SB.msgc-1 gastric cancer cells, derived from a patient with sporadic gastric cancer, were screened in 1536-well microplates for growth inhibition using the MIPE 4.0 Oncology Library which includes 1912 oncology compounds which are either clinically approved or currently in late preclinical development. This evidence concerns the gene CDH1 and gastric cancer.
