This article explores the role of lysin nanocarriers in inducing apoptosis of human hepatocellular carcinoma cells and the possible molecular mechanisms. Cytotoxicity tests were performed in human fibroblast cell line MRC-5. Anti-cancer activity was tested in liver cancer cell lines HepG2 and HCCLM3. The results show that nanocarriers have a targeting effect on cancer cells, have high safety, and are good delivery vehicles for drugs. In this paper, the stability of lycopene and its degradation in aqueous solutions at different temperatures were studied, and the structure and mechanism of degradation products were determined. A new type of mesoporous silica nanocarrier was synthesized as a delivery carrier of lysin and its derivatives, which has a targeting effect on cancer cells and has a slow-release effect. Surface modification can improve circulation time and stability for future resistance in vivo. The cancer experiment laid the foundation. The results showed that the lysin nanocarriers inhibited the proliferation of HepG2 and HCCLM3 human liver cancer cells in a dependent manner. After the lysin nanocarriers acted on HepG2 human hepatocellular carcinoma cells for 48 h, the cell apoptosis rate was significantly increased by flow cytometry analysis. The carrier can significantly increase the levels of reactive oxygen species and malondialdehyde, and reduce the content of reduced glutathione and superoxide dismutase. At the same time, the lysin nanocarrier can down-regulate the expression of Nrf2 and HO-1 proteins, and inhibit the occurrence of Nrf2 Nuclear displacement. The lycopene nanocarrier inhibits the proliferation of HepG2, HCCLM3 human liver cancer cells, induces apoptosis, regulates the oxidative stress response in the cell, and regulates the Nrf2/AREE antioxidant signaling pathway, thereby promoting tumor cell apoptosis.
