        (1×10 -1  mmol/L)、5-FU组(10 μmol/L)、Irb低浓度+5-FU组(Irb 1×10 -3  mmol/L+5-FU 10 μmol/L)和Irb高浓度+5-FU组(Irb 1×10 -1
        mmol/L+5-FU 10 μmol/L),采用MTT法检测各组细胞的增殖活力;采用平板集落形成实验检测细胞集落形成数;采用Western blot
        法检测各组增殖细胞核抗原(PCNA)、p53、ERK1/2、磷酸化(p)-ERK1/2及PPARγ蛋白的表达水平。结果 与正常对照组比较,其余
        5组细胞增殖活力、细胞集落形成数以及PCNA、p-ERK1/2、PPARγ蛋白表达水平均显著降低/减少(P<0.05),p53蛋白表达水平均
        显著升高(P<0.05),ERK1/2蛋白表达水平无明显差异(P>0.05)。Irb低浓度+5-FU组和Irb高浓度+5-FU组上述指标变化趋势均
        显著高于Irb低浓度组、Irb高浓度组、5-FU组(P<0.05)。结论 Irb联合5-FU可抑制Lewis肺癌细胞增殖,且效果优于二者单用,其
        机制可能与抑制ERK/PPARγ信号通路有关。

        ABSTRACT    OBJECTIVE To explore the effects of irbesartan(Irb)combined with 5-fluorouracil(5-FU)on the proliferation
        and extracellular signal-regulated kinase(ERK)/peroxidase proliferator-activated receptor γ(PPARγ)signaling pathway of Lewis
        lung cancer cells. METHODS Lewis lung cancer cells from mice were divided into normal control(NC)group,Irb low-dose
        (LD)group(1×10 -3  mmol/L),Irb high-dose(HD)group(1×10 -1  mmol/L),5-FU group(10 μmol/L),Irb LD+5-FU group(Irb
        1×10  - 3  mmol/L+5-FU 10 μmol/L)and Irb HD+5-FU group(Irb 1×10  - 1  mmol/L+5-FU 10 μmol/L). MTT method was used to
        measure the activity of cell proliferation in each group. Plate colony formation experiment was used to determine the number of cell
        colonies formed in each group;Western blot method was used to detect the expression levels of proliferating cell nuclear antigen
        (PCNA),p53,ERK1/2,p-ERK1/2 and PPAR γ protein in each group. RESULTS Compared with the NC group,the cell
        proliferation activity,the number of colonies formed and the protein levels of PCNA,p-ERK1/2,and PPARγ were significantly
        reduced in the other five groups,and the protein level of p53 was significantly increased(P<0.05);the protein expression of
        ERK1/2 had no significant difference(P>0.05). The changes of above indexes in Irb LD+5-FU group and Irb HD+5-FU group
        were more significant than Irb LD group,Irb HD group and 5-FU group(P<0.05). CONCLUSIONS Irb combined with 5-FU can
        inhibit the proliferation of Lewis lung cancer cell,and the effect is better than that of the two alone. The mechanism may be related
                                                            to the inhibition of ERK/PPARγ signal pathway.
