    • 摘要: 目的 探讨曲格列酮对低氧状态下肺动脉平滑肌细胞(PASMCs)的作用机制.方法 人PASMCs在37°C5%CO2+94%N2+1%O2条件下分别加入20μmol/L的曲格列酮培养72 h.通过聚合酶链反应(PCR)法测定PASMCs内PTEN、Caspase-3和Caspase-8基因表达;Western blot法测定PTEN,p-Akt,Akt蛋白的表达.结果 曲格列酮抑制低氧条件下PASMCs的增殖;曲格列酮组PASMCs PTEN mRNA和蛋白表达水平升高,曲格列酮增加了PASMCs的Caspase-3及Caspase-8活性;PTEN抑制剂bpV(HOpic)和PPARγ抑制剂GW9662可通过下调PTEN基因表达而逆转曲格列酮对PASMCs的增殖抑制作用.结论 曲格列酮可增强PTEN的表达,促进低氧条件下PASMCs的凋亡,同时通过PPARγ途径增强PTEN表达.

    • 摘要: 目的 探讨肝爽颗粒主要成分柚皮苷是否具有预防药物性肝损伤的功能以及保护作用的机制.方法 选取具有肝毒性的药物(曲格列酮和双氯芬酸钠)制造体外模型,预防性地应用不同浓度的柚皮苷,通过半数抑制率(IC50)、转氨酶水平、乳酸脱氢酶水平、Caspase3基因水平评价HL-7702细胞的损伤情况.评价不同浓度的柚皮苷对细胞色素P450(CYP450)家族基因的改变情况.结果 柚皮苷能够明显升高曲格列酮和双氯芬酸钠的IC50,具有降低转氨酶、Caspase3表达的作用.但这种改善具有剂量依赖性,其中100μmol/L柚皮苷的保护作用最明显,1μmol/L柚皮苷和10μmol/L柚皮苷的保护作用不明显.比较CYP代谢酶基因改变情况发现,100μmol/L柚皮苷能明显抑制其表达(P<0.05),1μmol/L柚皮苷和10μmol/L柚皮苷的抑制作用不明显.结论 肝爽颗粒主要成分柚皮苷能够通过抑制CYP450酶的功能,从而起到预防作用.

Methods The cultured mouse glomerular mesangial cells were divided into the blank group, TNF-α group, TNF-α+troglitazone group. The proliferation of mesangial cells was detected by MTT assay. The expression of intercel-lular adhesion molecule-1 (ICAM-1) protein in the supernatants of mesangial cells was determined by enzyme-linked immunosorbent assay (ELISA). The expression of nuclear factor-κB (NF-κB) in mesangial cells of different groups was determined by immunohistochemistry. Results The proliferation OD values of the glomerular mesangial cells in the TNF-αgroup at 6 hours, 12 hours, 24 hours and 48 hours were (0.198 ± 0.025), (0.241 ± 0.028), (0.286 ± 0.030), and (0.267 ± 0.042), respectively; the proliferation OD values of the glomerular mesangial cells in the blank group were (0.159±0.021), (0.161±0.019), (0.164±0.023) and (0.170±0.020), respectively;the proliferation OD values of the glo-merular mesangial cells in the TNF-α+ troglitazone group were (0.187 ± 0.023), (0.184 ± 0.017), (0.172 ± 0.018) and (0.168±0.026), respectively. The proliferation OD values of the glomerular mesangial cells of the TNF-αgroup were sig-nificantly higher than those of the blank group, and the OD values of glomerular mesangial cell proliferation of the TNF-α+troglitazone group were significantly lower than those of the TNF-αgroup, with statistically significant differ-ences (P<0.05). The positive rate of NF-κB protein in glomerular mesangial cells in the TNF-αgroup, blank group and TNF-α+troglitazone group were respectively (62.34±10.26)%, (29.97±4.88)%and (45.67±8.36)%;the positive rate of NF-κB protein in glomerular mesangial cells in the TNF-αgroup was significantly higher than that in the blank group;the positive rate of NF-κB protein in glomerular mesangial cells in the TNF-α+troglitazone group was significantly lower than that in TNF-αgroup and significantly higher than that in blank group, and all of the above differences were statistically significant (P<0.05). The concentration of ICAM-1 protein in glomerular mesangial cells in the TNF-αgroup, blank group and TNF-α + troglitazone group were respectively (967.8 ± 77.4) pg/mL, (571.2 ± 69.6) pg/mL and (787.5±81.2) pg/mL;the concentration of ICAM-1 protein in glomerular mesangial cells in the TNF-αgroup was signifi-cantly higher than that in blank group;the concentration of ICAM-1 protein in glomerular mesangial cells in the TNF-α+troglitazone group was significantly lower than that in TNF-α group and significantly higher than that in blank group,and all of the above differences were statistically significant (P<0.05). Conclusion TNF-αcan promote the prolifera-tion of glomerular mesangial cells and the expression of NF-κB protein and ICAM-1 protein, while troglitazone can in-hibit the proliferation of glomerular mesangial cells and decrease the expression of NF-κB protein and ICAM-1 protein.

    • 摘要: 目的 观察曲格列酮对宫颈癌SiHa细胞增殖的影响,并探讨S期激酶相关蛋白2(s-phase kinase associated protein 2,skp2)、p27在此过程中的作用. 方法 曲格列酮(0、100、200、400 μg/ml)处理人宫颈癌SiHa细胞,采用四甲基偶氮唑蓝(MTT)法测定细胞增殖活性,膜联蛋白-Ⅴ(Annexin Ⅴ)-FITC法检测细胞凋亡;流式细胞术检测细胞周期;倒置显微镜观察SiHa细胞形态学变化;构建skp2表达质粒并转染SiHa细胞,Western blot检测蛋白的表达. 结果 曲格列酮明显抑制宫颈癌SiHa细胞增殖,且呈明显时间及浓度依赖性(P<0.05);曲格列酮增加SiHa细胞周期G1/S期阻滞,细胞凋亡率未见显著性变化(P>0.05);曲格列酮上调SiHa细胞p27表达,下调skp2表达;过表达skp2可明显抑制曲格列酮对p27表达的升高作用,同时抵消曲格列酮对细胞周期抑制的作用. 结论 曲格列酮通过调节细胞周期而非凋亡途径,抑制宫颈癌SiHa细胞增殖,其机制可能与调节skp2、p27蛋白表达有关.%Objective To evaluate the effect and mechanisms of troglitazone on proliferation and apoptosis of SiHa cells.Methods SiHa cells were treated with a series of concentration of troglitazone (0,100,200,400 μg/ml).The inhibition rate of cell proliferation was detected at different periods by MTT method,and cell-cycle was analyzed by flow cytometry.S-phase kinase associated protein 2 (skp2) plasmid was transfected into SiHa cells and the effect of troglitazone on the expression of p27 and skp2 in SiHa cells was detected by Western blot analysis.Results Troglitazone inhibited the proliferation of SiHa cells at a time-and dose-dependent manner(P<0.05),while showing no effect on apoptosis in SiHa cells (P>0.05).Troglitazone attenuated skp2 expression,promoted p27 expression.Up-regulation of the expression of p27 and the inhibiting effect of the proliferation on SiHa cells by troglitazone were inhibited by over-expression of skp2.Conclusions By regulating the cell cycle rather than apoptotic pathways,troglitazone inhibits the proliferation of cervical cancer SiHa cell and its mechanism may be related to regulating skp2,p27 protein expression.

    • 摘要: Objective To investigate the effect of troglitazone, a proliferator-activated receptor-γ (PPARγ) agonist, on the expressions of intercellular adhesion molecule-1 (ICAM-1) and matrix metalloproteainse-9 (MMP-9) and cell proliferation in HeLa cells. Methods MTT assay was used to measure the cell viability at different time points (0, 24, 48 and 72 h) after exposure to troglitazone. RT-PCR and Western blotting were employed to detect the mRNA and protein expressions of ICAM-1, MMP-9 and PPARγin the cells. Electrophoretic mobility shift assay (EMSA) was performed to assess the changes in DNA binding activity of PPARγ. Results The viability of HeLa cells were time-dependently inhibited by troglitazone, which also significantly reduced the mRNA and protein expressions of ICAM-1 and MMP-9 and increased PPARγexpression. The effects of troglitazone in inhibiting the cell viability and reducing ICAM-1 and MMP-9 expressions were antagonized by the application of the PPARγantagonist GW9662. The result of EMSA also showed significantly increased DNA binding activity of PPARγin the cells exposed to troglitazone. Conclusions The PPARγagonist troglitazone can inhibit the expression of ICAM-1 and MMP-9 in HeLa cells by up-regulating PPARγ.%目的:探讨PPARγ激动剂曲格列酮对于宫颈癌HeLa细胞增殖及ICAM-1和MMP-9表达的影响。方法使用曲格列酮和/或GW9662(PPARγ拮抗剂)对HeLa细胞进行干预。在不同时间点(0、24、48和72 h)使用MTT法对HeLa细胞活性进行测定。在干预48 h后,使用RT-PCR和western blot对HeLa细胞ICAM-1、MMP-9和PPARγmRNA和蛋白进行测定。并使用EMSA对HeLa细胞PPARγDNA结合能力(核转录水平)进行分析。结果 GW9662组、曲格列酮+GW9662组与空白对照组相比较各时间点细胞活性未见显著统计学差异(P>0.05);但曲格列酮组与空白对照组相比较细胞活性呈时间依赖性降低,差异有显著统计学意义(P均0.05)。曲格列酮干预后HeLa细胞PPARγmRNA和蛋白表达水平和PPARγ核转位水平均显著增加,差异有显著统计学意义(P均<0.05)。结论本实验表明曲格列酮可以通过促进PPARγ表达和PPARγ的核转录水平下调HeLa细胞ICAM-1和MMP-9的合成,抑制HeLa细胞的增殖。

    • 摘要: 目的 初步探讨过氧化物酶体增殖物激活受体(PPARγ)激动剂对体外培养海马神经元轴突生长的作用及其机制.方法 通过向原代培养的胎鼠海马神经元中加入PPARγ激动剂曲格列酮(TGZ)及其抑制剂GW-9662 (GW)以及JNK特异性抑制剂SP 600125 (SP),以研究PPARγ激动剂对海马神经元轴突生长的作用,以及JNK通路的活化在此过程中的作用.结果 TGZ活化PPARγ后能明显促进海马神经元轴突的延长(P<0.05).PPARr拮抗剂GW消除了TGZ的促轴突生长作用.PPARγ活化后激活了JNK通路,且JNK特异性抑制剂SP能明显阻断TGZ的促轴突生长作用(P<0.05),表明TGZ诱导的促轴突生长作用依赖JNK通路的激活.结论 PPARr激动剂能促进海马神经元轴突的生长,且此作用依赖JNK通路的激活.
