The target proteins implicated in gastric cancer, specifically HIF1A, HSP90AA1, MMP9, ERBB2, and PTGS2, were matched with the key metabolites from the Vaccinium genus, including cyanidin 3-O-glucoside, ursolic acid, resveratrol, scopoletin, and (+)-catechin. Here, ERBB2 is linked to gastric cancer.
