Abstract:

BACKGROUND: Suicide gene system without selectivity not only kills cancer cells, but also has the same effect on normal cells, so the construction of targeting vector of gene therapy has become an urgent problem to be solved.
OBJECTIVE: To evaluate killing effects of apolipoprotein E modified liposomes (apoE-lipoplexes) mediated TK/ganciclovir suicide gene transfection on hepatocellular carcinoma Li-7 cells.
METHODS: The apoE-lipoplexes packed pAFP-TK-IRES2-EGFP eukaryotic expression plasmids were transfected into Li-7 cells. HSVtk stably expressing cell clone (Li-7-tk) was screened. Fluorescence microscopy was used to observe the expression of enhanced green fluorescent protein. HSVtk gene expression was detected using western blotting. MTT method was used to evaluate the killing effects of HSVtk/GCV system on Li-7 cells.
RESULTS AND CONCLUSION: Stable clone (Li-7-tk) was obtained through screening suicide gene transfected Li-7 cells. After HSVtk/ganciclovir system acting on Li-7 cells, cell apoptosis rate was significantly increased (P < 0.01). In alpha fetoprotein-positive hepatocellular carcinoma cell line Li-7, suicide gene vector expresses stably and effectively kills cancer cells.
