To evaluate the effects of Fuzheng Yiliu Granules (FZYLG) on apoptotic rate and mitochondrial membrane potential (Delta psi m) of hepatocellular carcinoma cell line H22 from mice.
Forty-eight mice inoculated with H22 cells were randomly divided into four groups: untreated group, cyclophosphamide-treated group, high-dose FZYLG-treated group and low-dose FZYLG-treated group. After 14 days of corresponding treatment, H22 cells in each group were stained with propidium iodide, and the apoptotic rates were detected by flow cytometry (FCM). The rhodamine 123 was used as a fluorescence probe to label the H22 cells, and the fluorescence intensities were observed with laser scanning confocal microscope. The fluorescence intensity of H22 cells indicated the Delta psi m of H22 cells.
FZYLG could significantly increase the apoptotic rate while reduce the Delta psi m of H22 cells from mice as compared with those in the untreated group.
The antitumor effects of FZYLR on H22 cells from mice are related to decreasing the Delta psi m and then inducing the apoptosis of the H22 cells.
评价扶正抑瘤颗粒(FZYLG)对小鼠肝癌细胞系H22凋亡率及线粒体膜电位(Δψm)的影响。
将接种H22细胞的48只小鼠随机分为四组:未治疗组、环磷酰胺治疗组、高剂量FZYLG治疗组和低剂量FZYLG治疗组。经过14天的相应治疗后,用碘化丙啶对每组中的H22细胞进行染色,并用流式细胞术(FCM)检测凋亡率。用罗丹明123作为荧光探针标记H22细胞,并用激光扫描共聚焦显微镜观察荧光强度。H22细胞的荧光强度表示H22细胞的Δψm。
与未治疗组相比,FZYLG可显著提高小鼠H22细胞的凋亡率,同时降低其Δψm。
FZYLR对小鼠H22细胞的抗肿瘤作用与降低Δψm进而诱导H22细胞凋亡有关。
