A search of the literature showed that harmine induces the apoptosis of gastric cancer cells by down‐regulating cyclooxygenase‐2 (COX‐2) expression (Yu et al., 2016) and that chrysin inhibits COX‐2 expression in macrophages and induces Akt inactivation in U937 cells (Woo, Jeong, Inoue, Park, & Kwon, 2005). This evidence concerns the gene AKT1 and gastric cancer.
