Then, using the Merge plug-in, the intersection targets of ginsenoside Rb1 in the treatment of gastric cancer were extracted, and then the key targets of ginsenoside Rb1 in the treatment of diseases were screened, such as Neurotrophic receptor tyrosine kinase 1 (NTRK1), Fibronectin 1 (FN1), Minichromosome maintenance complex component 2 (MCM2), Inhibitor of nuclear factor kappa B kinase subunit gamma (IKBKG), AKT serine/threonine kinase 1 (AKT1) and other 45 targets, as shown in Figure 1A. This evidence concerns the gene MCM2 and gastric cancer.
