Objective This article aims to study the impact of cyclopamine,a Hedgehog signaling pathway inhibitor,on the proliferation and apoptosis of QBC939 cholangiocarcinoma cells.Methods The proliferation of QBC939 cells was detected with the MTT assay,and the apoptotic rate was analyzed with the flow cytometry assay.RT-PCR and Western blow were used to detect the expressions of tumor-related genes and proteins in QBC939 cells before and after cyclopamine treatment.Results Our results show that cyclopamine inhibited the growth of QBC939 cells in time and dose dependent manners.After a 5,10,or 20 μmol/L cyclopamine treatment for 48 hours,QBC939 cells showed increased apoptotic rates significantly higher than those in the control group (P<0.01).Furthermore,cyclopamine down regulated the mRNA and protein levels of PTCH1,GLI1,and EGFR in QBC939 cells.Conclusion Therefore,blockage of the Hedgehog signaling pathway with cyclopamine could suppress the proliferation and promote the apoptosis of QBC939 cholangiocarcinoma cells.

Objective To evaluate the response of the lung tumor xenografts in nude mice to antiangiogenic treatment from perspectives of anatomic,vessel function,cellular and molecular level using the multimodality imaging techniques including optical imaging,dynamic contrast enhanced MRI(DCE-MRI)and diffusion weighted imaging(DWI).Methods The green fluorescent protein(GFP)was transplanted labeled using GFP-expressing NCI-H460 cells.After the transfection of GFP,NCI-H460 cells were implanted subcutaneously into nude mice.Ten days after implantion,12 nude mice whose tumor xenografts grew to 0.5-1.0 cm in the maximum diameter were randomly divided into 2 groups,and injected with phosphate-buffered saline and recombinant human endostatin respectively.Then the nude mice in the two groups underwent optical imaging,DCE-MRI and DWI.The volumes,photon counts,the quantitative MR vessel functional parameters including volume transfer constant(Ktrans),rate constant(Kep),volume of extravascular extracellular space(Ve)and maximum area under the enhancement curve(iAUC),and apparent diffusion coefficient(ADC)values of the tumors were recorded.Then tumors were collected and observed using the transmission electron microscopy and pathology examination,including HE staining,microvessel density(MVD)and the expressions of vascular endothelial cell growth factor(VEGF).The Kep and VEGF expressions in experimental group and control group were compared with x2 text,and other values were compared with t test.The Pearson and Spearman test were used for analyzing the correlation of values in the two groups.Results Seven days after inoculation,the fluorescence signals were detected and grew with the growth of the tumors.On the 7 day after starting therapy,the photon counts of experimental group and control group were(2.51 ± 2.43)× 1010(photon/sec)and(5.77 ± 3.25)× 1010(photon/sec),respectively with no significant differences(t =1.964,P >0.05).Two sample t test showed that the tumor volumes in experimental group were smaller than those in control group[(365 ± 56)vs(987 ± 265)mm3,t =0.001,P < 0.01].There was a positive correlation(r =0.673,P < 0.05)between the photon counts and the volumes of the tumors.The mean Ktrans,Kep,Ve and iAUC of experimental group were:(0.055 ±0.012)min-1,0.335(0.184—0.894)min-1,0.297 ± 0.041 and 7.334 ± 3.930,and those for control group were:(0.117 ± 0.027)rin-1,0.417(0.324-1.736)min-1,0.326:±:0.062 and 13.280 ± 4.245.There were significant differences of Krans and iAUC(t =5.155,2.518,P < 0.05)between experimental group and control group.And there was a positive correlation(r =0.715,P < 0.0 1)between the values of iAUC and MVD,but not the expressions of VEGF(r =0.484,P > 0.05).The values of ADC in experimental group were higher than that in control group[(791 ± 38)× 10-6 vs(737 ± 43)×10-6 mm2/s],and there were significant differences(t =-2.299,P < 0.05).Two sample t test showed that the MVD in experimental group were lower than that in control group[(11.9 ± 4.8)vs(19.2 ±4.3)item/hpf,t =2.774,P < 0.05].The VEGF expressions in experimental group were lower than that in control group(x2 =4.000,P > 0.05).It was observed that some cells in experimental group had degenerated and apoptotic signs by the electron microscopy.Conclusions Evaluating the response of lung tumor xenografts to antiangiogenic treatment at anatomical,vessel functional,cellular and molecular level using the multimedality imagings is applicable.And it will be in favour of evaluating the therapeutic effect promptly.

Objective To investegate the effect of ginsenoside Rg1 on the apoptosis related protein FLICE-inhibitory protein(FLIP),Fas-associated death domain protein (FADD)and Caspase-3 in the subatania nigra(SN)of 1-methyl-4-phenyl-1,2,3,6-tetrahyd-ropyridine (MPTP)-induced mouse models of Parkinson’s disease(PD), and to investigate the role of FADD and FLIP in the pathogenesis of PD and the protective effect of ginsenosides Rg1 on dopaminergic neurons.Methods 45 C57BL/6N mice were randomly divided into control group,model group and ginsenoside Rg1 group (n=15).The mice in model group were injected with MPTP by intraperitoneal,the mice in Rg1 group were injected with ginsenoside Rg1 before injecting MPTP,and the mice in control group were injected with normal saline by intraperitoneal. The behavioral changes of the mice in various groups were observed, and immunohistochemistry and Western blotting methods were used to observe the expressions of tyrosine hydroxylase (TH),FADD,FLIP and Caspase-3 in substantia nigra of the mice.Results Compared with control group,the mice in model group presented with typical symptoms of PD, the TH-positive neurons in the subatania nigra was significantly reduced (P<0.01 ), the number of FADD, FLIP and Caspase-3 positive cells was significantly increased(P<0.01),and the cytoplasm was deeply stained;the protein expression levels of FADD,FLIP and Caspase-3 were significantly increased (P<0.01).Compared with model group,the PD symptoms of the mice in ginsenoside Rg1 group reduced, the number of TH-positive neurons was significantly increased, the number of positive cells of FLIP,FADD and Caspase-3 were significantly reduced(P<0.01),and the cytoplasm was lightly stained;the protein expression levels of FADD, FLIP and Caspase-3 were significantly reduced (P<0.01 ). Nonlinear correlation analysis found that there was a positive relationship between the number of FADD and Caspase-3 positive cells (r=0.791,P<0.05).Conclusion Ginsenoside Rg1 may play a neural protective effect dopaminergic on neurons by modulating the FADD and FLIP expressions in SN of PD model mice.
