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 / 中华预防医学杂志

ABSTRACT

<p><b>OBJECTIVE</b>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.</p><p><b>METHODS</b>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.</p><p><b>RESULTS</b>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.</p><p><b>CONCLUSIONS</b>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.</p>
