摘要
目的:探讨肺经引经药桔梗的有效成分桔梗皂苷D分别配伍不同治则下中药有效成分麦冬总皂苷、莪术醇、蛇床子素对乳腺癌细胞增殖及侵袭的影响。方法:应用四甲基偶氮唑盐(methyl thiazolyl tetrazolium,MTT)比色法确定各成分抑制乳腺癌细胞4T1和MDA-MB-231增殖的有效剂量;采用均匀设计法进行桔梗皂苷D与不同治则下中药有效成分的配伍优化;通过MTT法和Transwell实验比较和验证各优化配伍抑制乳腺癌细胞增殖及侵袭的作用。结果:逐步回归分析得到桔梗皂苷D加麦冬总皂苷、桔梗皂苷D加蛇床子素、桔梗皂苷D加莪术醇抑制乳腺癌细胞增殖的最佳配伍剂量。验证实验显示,桔梗皂苷D加莪术醇、桔梗皂苷D加蛇床子素优化配伍对4T1和MDA-MB-231细胞增殖的抑制效果明显优于桔梗皂苷D加麦冬总皂苷及各成分单用(P<0.05或P<0.01);对于4T1细胞,桔梗皂苷D加麦冬总皂苷和桔梗皂苷D加蛇床子素优化配伍对细胞侵袭能力的抑制作用优于桔梗皂苷D加莪术醇及各成分单用(P<0.05或P<0.01);对于MDA-MB-231细胞,则以桔梗皂苷D加蛇床子素和桔梗皂苷D加莪术醇对细胞侵袭能力的抑制作用最强,优于桔梗皂苷D加麦冬总皂苷(P<0.01)。结论:桔梗皂苷D与不同治则中药有效成分优化配伍抑制乳腺癌细胞增殖和侵袭效果明确,不同的桔梗皂苷D配伍对效应指标的作用存在一定的差异。
OBJECTIVE： To investigate the effects of platycodin D in combination with different active ingredients of Chinese herbs under different therapeutic principles on proliferation and invasion of 4T1 and MDA-MB-231 breast cancer cell lines. METHODS： The effective doses of platycodin D, Ophiopogon total saponins, curcumenol and osthole in inhibiting proliferation of breast cancer cell lines 4T1 and MDA-MB-231 were detected by methyl thiazolyl tetrazolium （MTT） assay, respectively. Optimized combinations of platycodin D with Ophiopogon total saponins, curcumenol, or osthole were determined by uniform design method. Effects of the optimized combinations of platycodin D with the three ingredients on proliferation and invasion of 4T1 and MDA-MB-231 cells were verified and evaluated by MTT assay and Transwell chamber test, respectively. RESULTS： Verifying study showed that the inhibitory effects of platycodin D in combination with curcumenol or osthole on proliferation of 4T1 and MDA-MB-231 cells were better than those of platycodin D in combination with Ophiopogon total saponins and each ingredient used alone （P〈0.05 or P〈0.01）. The inhibitory effect of platycodin D in combination with Ophiopogon total saponins or osthole on invasion of 4T1 cells was significantly better than those of platycodin D in combination with curcumenol and each ingredient used alone （P〈0.05 or P〈0.01）. Moreover, the inhibitory effect of platycodin D in combination with curcumenol or osthole on invasion of MDA-MB-231 cells was significantly better than that of platycodin D in combination with Ophiopogon total saponins （P〈0.01）. CONCLUSION： The optimized combinations of platycodin D with three different active ingredients of Chinese herbs under different therapeutic principles can significantly inhibit the proliferation and decrease the invasion of 4T1 and MDA-MB-231 cells. Different platycodin D combinations have different potency in suppressing breast cancer cell proliferation and invasion.
