Thus playing an antitumor immune role.[28] In an in vivo experiment on tumor-bearing mice, Yang B et al found that Astragalus polysaccharide could increase the production and expression of NO, IL-1β, IL-6, and TNF-α in tumor-bearing mice, thereby enhancing the killing effect on tumor cells of tumor-bearing mice and inhibiting tumor growth and metastasis.[29] Chinese yam and tremella tremella, as the typical representatives of the homology of medicine and food, have obvious immunomodulatory effects due to their main active ingredients. The gene discussed is IL1B; the disease is neoplasm.
