Results were shown as followings:(1) Sodium selenite at 0～2.5 μmol/L significantly increased the antioxidative capacity of L-02 cells without having remarkable impact on SMMC-7721 cells;(2) Sodium selenite at concentrations above significantly increased telomerase activity, hTERT gene expression and telomere length of L-02 cells without significant impact on SMMC-7721 cells;(3) Sodium selenite at higher concentrations (larger than 5 μmol/L) resulted in peroxidation of L-02 cells, while scutellarin significantly counteracted its effect;(4) Selenium-rich amino acids from silkworm pupas in the range of 0.5～2.5 μmol/L Se significantly inhibited SMMC-7721 cell growth, induced apoptosis and cell cycle change, and the generation of reactive oxygen species. In contrast, sodium selenite and selenomethionine only had weak impact on them at the same concentrations;(5) A new selenium-containing protein was found from selenium-rich silkworm pupas, which is worthy to be study further;(6) An expression vector containing ansense RNA of hTERT gene were constructed and used to transfect SMMC-7721 cells.
