“The triterpenoids of southern snake vine can inhibit the proliferation and migration ability of gastric cancer cells by regulating the polarization state of macrophages. Its mechanism of action may be closely related to the Toll like receptor 4/nuclear transcription factor - κ B (TLR4/NF - κ B) signaling pathway regulating epithelial mesenchymal transition (EMT) process. The research team explored the intervention strategy of traditional Chinese medicine active ingredients targeting the tumor microenvironment, opening up a new direction for the treatment of gastric cancer.”
