为了解橙盖鹅膏菌中分离得到的过氧麦角甾醇对人卵巢癌A2780S细胞增殖的影响及其可能的机制,取对数生长期的A2780S细胞,经1.10、2.19、4.38、8.75、17.5、35μ.mol/dL等浓度下的过氧麦角甾醇作用,以CCK-8法测试24、48和72 h后细胞增殖;经2.19、4.38、8.75.μmol/dL浓度的过氧麦角甾醇作用24 h后,倒置显微镜下观察细胞形态,DAPI染色法观察细胞核形态,Annexin V/PI双染流式细胞术测定细胞的早期凋亡率,PI单染流式细胞术测定细胞周期.结果显示,过氧麦角甾醇作用于人卵巢癌A2780S细胞后,17.5 μmol/dL、35 μ.mol/dL浓度组48 h、72 h出现大量细胞死亡,贴壁存活细胞数目明显减少,细胞核呈现核浓缩的高量区域及月牙状的特征,细胞早期凋亡率、细胞S期比例显著增加.本研究表明过氧麦角甾醇对A2780S细胞增殖具有明显抑制作用,可能与其阻滞细胞周期和诱导细胞凋亡有关.
The effect of ergosterol peroxide isolated from Amanita caesarea on the proliferation of ovarian cancer cells A2780S
This research aimed to study the proliferation of ovarian cancer cells A2780S induced by ergosterol peroxide isolated from Amanita caesarea.A2780S cells on the logarithmic growth phase were treated by ergosterol peroxide at the doses of 1.10,2.19,4.38,8.75,17.5 and 35 μmol/dL for 24,48 and 72 h,and cell proliferation was determined by CCK-8 assay.After treatment at dose of 2.19,4.38 and 8.75 μmol/dL for 24 h,the cell morphology was observed by inverted microscope and cell nuclear morphology was observed by DAPI assay.The early apoptosis rate of cells was determined by Annexin WPI doublestaining flow cytometry and the cell cycle was determined by PI cytometry.Ergosterol peroxide was found to inhibit the proliferation of A2780S.It increased the exfoliative and necrotic cells,and significantly increased the proportion of cells in S phase and early apoptosis of cells.The inhibition of A2780S cell proliferation by ergosterol peroxide may be through cell cycle blockage and cell apoptosis induction.
