摘要: 目的研究右旋柠烯(D-limonene)对人结肠癌细胞(LS174T)中信号传导分子ERK1/2、Akt及其磷酸化蛋白(p-ERK和p-Akts蛋白)表达的影响。方法 采用四甲基偶氮唑盐(MTT)方法检测右旋柠烯对LS174T细胞增殖的抑制作用;采用Western blot方法检测不同浓度右旋柠烯对LS174T细胞中ERK1/2、Akt及其磷酸化蛋白表达情况的影响。结果 右旋柠烯作用LS174T细胞48h后,呈剂量依赖性抑制细胞增殖;Western blot结果显示右旋柠烯对细胞中ERK1/2、Akt蛋白的表达没有明显影响,但显著下调p-ERK1/2蛋白和p-Akts的表达。结论 右旋柠烯抑制LS174T细胞增殖可能与其抑制p-ERK1/2和p-Akts表达有关。

Abstract: Objective To investigate the effect of D-limonene on the expressions of p-ERK and p-AKTs in human colon cancer cell line LS174T.Methods The effect of D-limonene on the cell proliferation was measured by methyl thiazolyl tetrazolium(MTT),and the expression of ERK1/2,Akt and their phosphorylated proteins(p-ERK and p-AKTs)were detected by Western blot.Results D-limonene inhibited the proliferation of LS174T cell in a dose dependent manner,because the LS174T cell were exposed to D-limonene for 48 hours.D-limonene did not influence the expressions of ERK1/2 and Akt,but it significantly decreased p-ERK1/2 and p-Akts expressions.Conclution It is suggested that D-limonene could inhibit proliferation of LS174T cell via inhibiting the p-ERK1/2 and p-Akts pathway.
