Abstract:

Background: Bioactive Hepatic Peptide (BHP), a kind of bioactive peptide from goat liver, can regulate immune function in healthy mice. However, how the tumor-bearing mice? We investigated the effect of BHP on the immune function of gastric cancer-bearing nude mice and its possible underlying mechanism.
Methods: Nude mice were inoculated into the neck with human BGC-823 gastric cancer cells to establish the subcutaneous transplanted tumor model group. The percentage of peripheral blood lymphocytes was measured by flow cytometry. Hematoxylin-Eosin (HE) staining was used. The mRNA expression levels were measured by real-time fluorescence quantitative PCR and the protein expression of NF-κB, TNFα, Beclin1, LC3B, Akt1, COX-2 were determined by immunohistochemistry and Enzyme-Linked Immunosorbent Assay (ELISA).
Results: BHP could inhibit tumor cell proliferation, improve the percentage of NK cells/B lymphocytes, phagocytic index and phagocytic percentage and reduce the degree of inflammatory infiltration in tumor-bearing nude mice. BHP could significantly decrease the mRNA and protein expression of NF-κB, TNF-α in spleen and AKT1 and COX-2 in tumor tissue, but it could
significantly increase the mRNA and protein expression of Beclin1 and LC3B (LC3) in tumor tissue (P<0.05). The levels of NF- κB, TNFα and COX-2 were significantly lower in the serum of nude mice treated with BHP (P<0.05). The level of Beclin1 increased significantly after BHP treatment (P<0.05).
Conclusion: BHP may down regulate NF-κB/AKT1 to inhibit inflammation and induce autophagy, thus enhancing the immune function and antitumor effect of tumor-bearing nude mice. These findings support BHP as an immune-boosting health food/drug for cancer patients.
