目的

研究二甲双胍及单磷酸腺苷活化蛋白激酶(AMPK)抑制剂(compound C)对体外培养的小鼠乳腺癌4T1 细胞株增殖抑制及细胞周期蛋白D1(cyclin D1)表达的影响,进一步探索AMPK 通路在二甲双胍抗肿瘤的可能作用。

方法

体外培养小鼠乳腺癌4T1 细胞株至对数生长期,分别以2.5、5、10、20、40 mmol/L 二甲双胍及20 μmol/L compound C 对其进行单一或10 mmol/L 二甲双胍联合20 μmol/L compound C 干预24、48、72 h。 应用CCK-8 方法检测不同浓度的二甲双胍、20 μmol/L compound C、20 μmol/L compound C+10 mmol/L 二甲双胍对该细胞株增殖的抑制情况; Western blot 法检测各组细胞内cyclin D1 的表达情况。 多组比较采用单因素方差分析,两两比较采用q 检验,治疗前后用重复测量数据资料的方差分析。

结果

CCK-8 法结果显示在体外细胞培养实验中2.5 mmol/L 二甲双胍组作用于该细胞株24、48 h 后分别和正常对照组比较,细胞存活率差异无统计学意义(24 h: F=2.87, P=0.129;48 h:F=1.63, P=0.290),作用72 h 后, 差异有统计学意义(F=6.40, P=0.000)。 5、10、20、40 mmol/L 二甲双胍组作用于该细胞株24、48、72 h 后,该细胞株的增殖被显著抑制(均P=0.000),且抑制程度随着药物浓度的增大(F=332.89、363.54、352.11,P 均=0.000)及作用时间的延长而逐渐增强,compound C 单独处理组及10 mmol/L 二甲双胍联合20 μmol/L compound C 处理细胞24、48、72 h 后,细胞存活率与正常对照组相比较,差异无统计学意义(F=1.08,P=2.283; F=1.92, P=0.050)。 Western blot 结果显示随着二甲双胍浓度的增加,各组细胞cyclin D1 表达水平逐渐降低(F=54.41、61.69、75.84, P 均=0.000),10 mmol/L 二甲双胍联合20 μmol/L compound C 作用时,与正常对照组比较,cyclin D1 表达水平无明显变化(F=1.87, P=0.190)。

结论

二甲双胍可以抑制小鼠乳腺癌4T1 细胞的增殖; compound C 可以拮抗二甲双胍的抑制作用;二甲双胍通过激活小鼠乳腺癌4T1 细胞内AMPK,下调cyclin D1 蛋白表达。

Objective

To evaluate the effects of metformin alone or in combination with AMPK inhibitor compound C on proliferation and cyclin D1 expression in mouse breast cancer 4T1 cells and explore the possible role of AMPK pathway in the antitumor mechanism of metformin.

Methods

The mouse breast cancer 4T1 cells were cultured in vitro until the logarithm growth period, and then treated with 2.5, 5, 10, 20,40 mmol/L metformin and 20 μmol/L compound C respectively and 20 μmol/L compound C combined with 10 mmol/L metformin for 24,48,72 h. CCK-8 method was used to study the effects of metformin with different concentrations,20 μmol/L compound C+10 mmol/L metformin, 20 μmol/L compound C on cell proliferation.The expression of cyclinD1 was detected with Western blot method. Multiple group comparison was performed by F test, pairwise comparison by q test, analysis of variance for repeated measurement data before and after treatment.

Results

CCK-8 test showed that in vitro cell culture, at 24, 48 h after 2.5 mmol/L metformin treatment, there was no significant difference in cell survival compared with control group(24 h:F=2.87,P=0.129;48 h:F=1.63, P=0.290), but a significant difference was observed at 72 h (F=6.40, P=0.000).at 24,48 and 72 h after 5,10,20,40 mmol/L metformin treatment, the proliferation of mouse breast cancer 4T1 cells was significantly inhibited by metformin in a dose-dependent and time-dependent manner(F=332.89,363.54,352.11, all P=0.000). Meanwhile in compound C group and 10 mmol/L metformin plus compound C group, cell survival showed no significant difference compared with the control group(F=1.08, P=2.283;F=1.92,P=0.050). The results in Western blot analysis, the expression of cyclin D1 decreased with the increase of metformin concentration (F=54.41, 61.69, 75.84, all P=0.000), but showed no significant difference(F=1.87, P=0.190) between 10 mmol/L metformin plus compound C group and control group.

Conclusions

Metformin can inhibit the cell proliferation of mouse breast cancer 4T1 cells, but compound C can antagonize the inhibition of metformin. Metformin can decrease cyclin D1 protein expression by activating AMPK pathway in mouse breast cancer 4T1 cells.
