【摘要】 [Objectives] To study the effects of volatile oils of Sichuan Citrisarcodactylis fructus on proliferation and apoptosis of MCF-7human breast cancer cells.[Methods]CCK-8 method was used to measure the cell proliferation,the flow cytometry was used to measure changes in cell cycle,Western blot was used to detect p53 and cyclin D1 activity changes,TUNEL method was used to measure percentage of apoptotic cells,inverted phase contrast microscope and transmission electron microscope were used to observe morphology of MCF-7 cells treated with different concentrations.[Results]When the concentration was 5-50 μmol/L,the cell proliferation inhibition rate increased significantly(P <0. 05),G2/M phase decreased significantly( P < 0. 05),eventually disappeared completely,G1 phase significantly increased with time and concentration( P < 0. 05),finally reached 90. 0%; the activity of cyclin D1 significantly declined( P < 0. 05),while the activity of p53 had no significant change( P > 0. 05). The apoptotic rate of MCF-7 cells significantly increased with the extension of time( P < 0. 05). At6 h,12 h and 24 h of action time,the apoptotic rate of MCF-7 cells significantly increased with the increase in volatile oil concentration(P <0. 05). Morphological observation showed that the apoptosis of MCF-7 cells was obvious.[Conclusions]The volatile oils of Citrisarcodactylis fructus have obvious inhibition of proliferation of MCF-7 cells and function of inducing apoptosis,and the effects took on the dose and time dependent. 5-50 μmol/L volatile oil of Sichuan Citrisarcodactylis fructus can inhibit the proliferation of MCF-7 cells and induce the apoptosis of MCF-7 cells through inhibiting the cyclin D1.
