[Effects of garlic oil combined with resveratrol on inducting of apoptosis and expression of Fas, bcl-2 and bax in human gastric cancer cell line].
OBJECTIVE
To explore the effects of garlic oil combined with resveratrol on the apoptosis and expression of Fas, bcl-2 and bax in human gastric cancer cell line MGC-803.


METHODS
The experiment included three groups which were the control group, the combined medicine group 1 (including 25 microg/ml oil garlic and 25 microg/ml resveratrol) and the combined medicine group 2 (including 50 microg/ml oil garlic and 50 microg/ml resveratrol). The apoptosis of cell was examined by DNA gel electrophoresis and flow cytometry for annexin v; the expression of Fas was determined by flow cytometry at the 24th hour after the treatment; the mRNA expression of bcl-2 and Bax gene were measured by RT-PCR method at the 24th ang 48th after treatment, respectively.


RESULTS
The garlic oil combined with resveratrol induced cell apoptosis markedly at the 24th after the treatment The protein expression of Fas in the combined medicine groups was 10.59% and 14.16% respectively. As compared with the control group (5.27%), the statistical significance was obvious. The mRNA level of Bax was elevated significantly, however the mRNA expression of bcl-2 was decreased at the 24th and 48th after the treatment.


CONCLUSIONS
The garlic oil combined with the resveratrol might obviously induce the apoptosis of gastric cancer cell line MGC-803 which be involved in increasing the expression of Fas protein and bax gene and decreasing the expression of bcl-2 gene at the same time.
