| 摘 要： | 研究目的：探讨萎叶（PB）提取物对5-氟尿嘧啶（5-FU）抑制结肠癌细胞HT29和HCT116生长的影响。研究方法：HT29和HCT116细胞分别给予PB、5-FU以及两种药物联合治疗24小时,应用等效线图法分析PB和5-FU的药效学相互作用,AnnexinV／PI染色法检测HT29和HCT116细胞的凋丁L=情况,高效液相色谱法排除PB和5-FU间任何可能的相互化学作用。重要结论：联合PB,低剂量5-FU可以在短时间内起到细胞毒作用,而单独应用PB或5-FU治疗较联合治疗可以诱导更多细胞发生凋亡。进一步采用等效线图法分析显示PB和5-Fu的联合作用在抑制结肠癌细胞HT29和HCT116的生长中分别体现出协同和拮抗作用。因此可以认为在HT29细胞中,PB使得较低剂量5-FU发挥最大抑制结肠癌细胞生长效果,然而在HCT116细胞中,PB没有显著降低5-FU的药物浓度,说明PB和5-FU的相互作用不仅仅体现在诱导细胞凋亡方面。 |

| Abstract: | ObjectiveThe combination effect of Piper betle (PB) and 5-fluorouracil (5-FU) in enhancing the cytotoxic potential of 5-FU in inhibiting the growth of colon cancer cells was investigated.MethodsHT29 and HCT116 cells were subjected to 5-FU or PB treatment. 5-FU and PB were then combined and their effects on both cell lines were observed after 24 h of treatment. PB-5-FU interaction was elucidated by isobologram analysis. Apoptosis features of the treated cells were revealed by annexin V/PI stain. High-performance liquid chromatography (HPLC) was performed to exclude any possible chemical interaction between the compounds.ResultsIn the presence of PB extract, the cytotoxicity of 5-FU was observed at a lower dose (IC50 12.5 μmol/L) and a shorter time (24 h) in both cell lines. Both cell lines treated with 5-FU or PB alone induced a greater apoptosis effect compared with the combination treatment. Isobologram analysis indicated that PB and 5-FU interacted synergistically and antagonistically in inhibiting the growth of HT29 and HCT116 cells, respectively.ConclusionsIn the presence of PB, a lower dosage of 5-FU is required to achieve the maximum drug effect in inhibiting the growth of HT29 cells. However, PB did not significantly reduce 5-FU dosage in HCT116 cells. Our result showed that this interaction may not solely contribute to the apoptosis pathway. |
