All docking binding energies were less than -5.0 kcal/mol, indicating that there was good binding capacity between Banxia-Shengjiang drug pair and the 5 core targets.[60] The top 5 results with the lowest docking energies were finally selected for visualization and labeled with the crystal structure names and docking energy sizes of the hub genes (Fig. 11), among which MMP9 and PTGS2 had the relatively lowest binding energies to the components, which suggests to us that MMP9 and PTGS2 may be the main target genes for the anti-gastric cancer effect exerted by Banxia-Shengjiang drug pair. This evidence concerns the gene MMP9 and gastric cancer.
