OBJECTIVE: To observe the effect of garlic oil combined with 5-FU induced apoptosis of adenoid cystic carcinoma cell line ACC-M. METHOD: Human salivary in adenoid cystic carcinoma cell line AC-M was cultured, divided into the experimental group (5-FU group, garlic oil group, garlic oil + 5-FU group) and the control group, to observe the growth activity of tumor cells by MTT methods; to analyse the changes of cell cycle and apoptosis rate by flow cytometry. RESULT: MTT experiments showed that 5-FU, garlic oil, garlic oil and 5-FU on ACC-M cells have inhibition in different concentration, with the increase of concentration and action time of the rise; Cell cycle analysis showed significant changes in flow cytometry. With the increase of concentration and the acting time, the G0/G1, phase of the cell ratio increased, S had no significant change, but G2/M phase cells decreased. Apoptosis rate display showed garlic oil combined with 5-FU induced apoptosis of ACC-M cells was significantly stronger than single group. CONCLUSION Garlic oil can effectively induce the apoptosis of adenoid cystic carcinoma cell line ACC-M. The effect of garlic oil combined with 5-FU on ACC-M cells was stronger than the garlic oil, 5-FU used alone.

OBJECTIVE: To observe the anticancer mechanism of allicin by observing the inhibitory effect of allicin on human salivary gland carcinoma cell line MEC-1. METHOD: Cell proliferation were measured by MTT assay at different doses and different hours. In the meantime, cell cycle was detected via flow cytometry after different dose incubation with different hours. RESULT: MTT results showed that the inhibitory rates of MEC-1 proliferations were increased in a concentration-and time-dependent manner. Flow cytometry analysis showed percent-age of MEC-1 cells decreased in G0/G1 phase and increased in G2/M. But there was no evident change in S phase. The cells were mainly blocked in M phase, and the inhibitory effect of the allicin on MEC-1 cells increased with the increasing of concentration and time. CONCLUSION Allicin can inhibit the growth of MEC-1 cells in vitro dramatically.

Objective : To investigate the effect and mechanism of allicin combined with 5-FU on proliferation inhibition and apoptosis of the mucoepidermoid carcinoma MEC-1 cell line in mucoepidermoid carcinoma in order to provide the corresponding basis for subsequent clinical drug application. Methods : MEC-1 cells in the logarithmic growth phase were randomly divided into control groups and experimental groups. The control groups were PBS groups containing 0.1% DMSO, while the experimental groups were the allicin group, 5-FU group and combined drug group (the allicin combined with the 5-FU group). The proliferation inhibition rates of allicin, 5-FU and allicin combined with 5-FU in MEC-1 cells were detected by the CCK8 method at different concentrations (0, 25, 50, and 75 mg/L) for 24 h, and the IC50 value of allicin and 5-FU after 24 hours was calculated. The apoptotic rate of MEC-1 cells treated with allicin, 5-FU and allicin combined with 5-FU at different concentrations (0, 25, 50, and 75 mg/L) for 24 hours was measured by flow cytometry. The expression of Bax and Bcl-2 protein was determined by Western blot analysis of the IC50 concentration of allicin and 5-FU alone and in combination with MEC-1 cells for 24 hours. Results: The growth inhibition rate and apoptosis rate of MEC-1 cells in the combined drug group were higher than those in the allicin group and the 5-FU alone group (P < 0.01). Allicin and 5-FU alone and in combination downregulated Bcl-2 protein and upregulated Bax protein expression, and the combined drug group had the largest ratio of Bax/Bcl-2 (P < 0.05). Conclusion Allicin and 5-FU both alone and in combination can inhibit the proliferation of and induce apoptosis in MEC-1 cells, and allicin can enhance the apoptosis of 5-FU in MEC-1 cells, which may be related to the apoptosis of the mitochondrial pathway.
