    Abstract:
    OBJECTIVE: To study the inhibitory effect of PCNA antisense oligonucleotides or/and VEGF antisense oligonucleotides on growth of human hepatocellular carcinoma in nude mice. METHODS: Human hepatocellular carcinoma transplanted subcutaneously in nude mice model was established, and subsequently was divided into four groups: PCNA-ASODN group, VEGF-ASODN group, combined group and control group. Different treatments were given respectively. The weigh and volume of subcutaneous tumors was measured, and the morphological changes of tumor cells was observed under microscope. RESULTS: The growth inhibitory rate in the PCNA-ASODN group was 72.8%, 44.9% in the VEGF-ASODN group, and 87.2% in the combined group. The combined group which was treated with PCNA-ASODN and VEGF-ASODN showed more effective inhibitory than the PCNA-ASODN group or the VEGF-ASODN group respectively. CONCLUSIONS: The growth of human hepatocellular carcinoma in nude mice can be inhibited by PCNA antisense oligonucleotides and VEGF antisense oligonucleotides respectively. Better inhibitory effect can be obtained if PCNA antisense oligonucleotides and VEGF antisense oligonucleotides are combined in use.
