It can be seen from Figure 3B that genes such as CYP3A4, CYP1A2, FOS, CCL2, CXCL2, CXCL10, CYP1A1, ADH1C, BAX, and CYP2B6 occupied a large rectangular area, indicating that these genes play a key role in the mechanism of PADP on the treatment of liver cancer. The gene discussed is BAX; the disease is liver cancer.
