Objective:
To investigate the therapeutic effects of Adenovirus-transferred antisense c-myc (Ad-Asmyc) on hepatocellular cancer cells and its mechanism.
Methods:
Human hepatocellular cancer cell line BEL-7402 and QSG-7701 were transfected with Ad-Asmyc. Cell growth curve and coloning formation were used to investigate the therapeutic effects of Ad-Asmyc in Vitro. The treating effects of Ad-Asmyc on transplanted tumor in nude mice was also studied. RT-PCR and Western blot were used to detect relating gene expression. Flowcytometry, DNA ladder and tunnel assay were used to study the cell cycle and apoptosis.
Results:
The expression of c-myc in cancer cells was reduced after infected Ad-Asmyc. Ad-Asmyc had obviously inhibiting effects on the growth of two hepatocellular carcinoma cell lines in vitro and also in vivo. It can induced cell cycle arrest (G1 arrest) and apoptosis.
Conclusion:
Ad-Asmyc can inhibit HCC cell proliferation and induce apoptosis, so has obvious therapeutic effects on hepatocellular cancer cells.

Cancer Therapies
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...
