    • 摘要: 目的探讨舒林酸对高脂饲养肥胖大鼠胰岛素敏感性的影响以及对胰岛素靶组织受体后信号转导途径蛋白表达及其磷酸化的调节作用。方法3周龄雄性SD大鼠20只随机分组给予普通饲料(5只)、高脂饲料(15只)饲养20周,用口服葡萄糖糖耐量试验筛选胰岛素抵抗造模成功大鼠共10只,再随机分组,予高脂饲料或高脂饲料加舒林酸干预,4周后以高胰岛素正葡萄糖钳夹试验评价不同干预组大鼠胰岛素敏感性变化。Western blot观察胰岛素受体底物1(IRS1)丝氨酸(Ser)/酪氨酸(Tyr)残基磷酸化水平的状态。结果高胰岛素正糖钳夹实验表明高脂饲养组大鼠葡萄糖清除率显著下降,提示胰岛素抵抗大鼠模型成功建立。舒林酸干预组大鼠葡萄糖清除率较高脂饲养组大鼠显著上升。舒林酸干预组大鼠骨骼肌IRS1酪氨酸磷酸化表达上调,而丝氨酸磷酸化表达下降。结论舒林酸通过调节IRS1 Ser/Tyr残基的磷酸化水平,改善高脂饮食肥胖大鼠的胰岛素敏感性。

    • 摘要: 目的 探讨儿童早期发病的家族性腺瘤性息肉病(FAP)的临床及基因突变特点.方法 回顾性分析2004年2月在北京大学第三医院确诊的1例FAP患儿的临床特点及11年随访期间内镜、病理表现,观察舒林酸的治疗效果,并采用PCR-DNA第一代测序法进行结肠腺瘤性息肉病(APC)基因突变分析.结果 患儿 女,6岁时因“间断大便带血1.5年”入院.结肠镜检查结肠和直肠可见数百枚息肉,病理结果示管状腺瘤Ⅱ~Ⅲ级.随访11年期间患儿临床表现为间歇黏液血便,内镜检查提示结直肠息肉逐渐增多至千枚,并出现胃底、胃体部多发息肉.13岁时加用舒林酸治疗后息肉数目及病理分级略有改善,息肉活检未发现癌变.尚未手术治疗.患儿基因检测提示APC基因15外显子1 309位存在杂合缺失(c.3927_3931 delAAAGA),其父母相应位点未见突变.父母肠镜未见多发息肉.结论 此例FAP患儿发病早,随年龄增长病情进展,舒林酸治疗对控制息肉大小及数目有部分疗效;突变位点符合经典型FAP,但无家族史,可能为散发突变.%Objective To explore the clinical features and molecular mutation of early-onset familial adenomatous polyposis(FAP) in childhood.Method The clinical features,endoscopic findings,pathology and therapeutic effect of sulindac during 11 years follow-up in a child with FAP were retrospectively reviewed.Adenomatous polyposis coli (APC) gene mutation analysis was performed by PCR and first generation sequencing.Result This 6-year-old girl was admitted for intermittent bloody stool during the last one and a half years.Colonoscopy showed hundreds of polyps in the rectum and colon.Pathological examination revealed tubular adenomas with high grade dysplasia.During the follow-up period of 11 years,the child presented intermittent mucous bloody stool.Endoscopy showed the number of polyps in colon and rectum increased to thousands,and found multiple polyps in gastric fundus and body.She was treated with sulindac at the age of 13.Then the number of polyps and the grade of pathology showed a slight improvement and no carcinoma was seen on biopsy.She has not accepted surgery until now.Gene sequencing of this child revealed 5 bp deletion at codon 1 309 of exon 15 (c.3927_3931delAAAGA) of tumor suppressor gene,whereas none of her parents had the same mutation.And no polyps were found on her parents colonoscopy.Conclusion This child with FAP had an early onset of this disease,and clinical conditions were exacerbated with age.Sulindac was partially effective in controlling size and number of polyps.The site of mutation in this case was consistent with classic FAP,and without family history,the mutation may be a sporadic one.

    • 摘要: Objective To test the effect of sulindac on autistic behaviors in a rat model and explore the possible mechanisms. Methods Autistic rat models were established by a single intraperitoneal injection of sodium valproate (VPA) at 12.5 days of pregnancy. The pregnant rats were treated with oral sulindac at a daily dose of 80 mg/kg until weaning of the newborn rats (23 days after being born), which were divided into control, VPA treatment, sulindac treatment, and VPA+ sulindac treatment groups. The social interaction and neuroethology of the newborn rats were evaluated at 35 days, and the levels of β-catenin and phosphorylated Gsk3βin the brain tissues were investigated by Western blotting. Results Compared with the control rats, the rats treated with VPA showed lower social interaction, longer moving time in central area, and reduced standing times. Treatment with sulindac alone resulted in no obvious changes in the social interaction or neuroethology of the newborn rats, but sulindac treatment corrected VPA-induced autistic-like behaviors. Sulindac also attenuated VPA-triggered p-Gsk3βdownregulation andβ-catenin upregulation in the prefrontal lobe, seahorse and cerebellum. Conclusion Sulindac can improve the behaviors of autistic rats possibly by suppressing Wnt signaling pathway.%目的 探讨舒林酸对孤独症模型大鼠病症行为的改善作用.方法 在大鼠怀孕12.5 d后采用一次性腹腔注射丙戊酸钠(VPA)制备孤独症大鼠模型.针对舒林酸处理组,于VPA注射后每天给大鼠口服20 mg/kg舒林酸直至断奶.将出生幼鼠分为4组:对照组,VPA处理组,舒林酸处理组及VPA联合舒林酸处理组.出生后35 d对幼鼠进行社会交往行为检测、敞箱焦虑样行为检测,并分离提取脑组织蛋白利用Western blot分析Wnt信号通路关键蛋白β-catenin与Gsk3β表达情况.结果 成功制备孤独症大鼠模型.与对照组相比,VPA处理组社会交往能力下降、在中央区活动时间增加、站立次数减少,符合孤独症行为特征;舒林酸单独处理组无明显行为学变化;但舒林酸联合处理能明显改善VPA处理导致的孤独症行为症状.Western blot结果显示,与对照组相比,VPA处理可增强大鼠前额叶、海马及小脑组织中β-catenin表达水平并降低Gsk3β第9位丝氨酸磷酸化水平;而舒林酸联合处理则能抑制上述脑组织中β-catenin表达水平并增加Gsk3β第9位丝氨酸磷酸化水平.结论 舒林酸可改善孤独症模型大鼠的病症行为,机制可能与抑制脑组织中Wnt信号通路相关.

    • 摘要: [ ABSTRACT] AIM:To investigate the effects of sulindac on oxidative stress in autism.METHODS:With an au-tistic model induced by prenatal exposure to valproic acid ( VPA) , we detected the expression of the signaling molecules of canonical Wnt pathway in the prefrontal cortex ( PFC) and hippocampus ( HC) of autistic rats treated with sulindac.The protein expression levels of glycogen synthase kinase 3β(GSK-3β), β-catenin and 4-hydroxynonenal (4-HNE) were ob-served by Western blotting.The mRNA expression of thioredoxin(Trx)1 and Trx2 was assessed by semi-quantitative RT-PCR.RESULTS:The protein level of GSK-3βand mRNA levels of Trx1 and Trx2 were lower, whereas the protein expres-sion levels ofβ-catenin and 4-HNE were higher in VPA group than those in control group.In contrast, the protein levels of GSK-3βwere significantly higher in the animals treated with both VPA and sulindac than those in VPA group, while the lev-els ofβ-catenin and 4-HNE were decreased.CONCLUSION:Sulindac attenuates oxidative stress in the pathogenesis of au-tism, suggesting the up-regulation of the Wnt/β-catenin signaling pathway disrupts oxidative homeostasis and further facili-tates susceptibility to autism.%目的:探讨舒林酸对孤独症发生过程中氧化应激变化的影响。方法:利用丙戊酸( VPA)孤独症动物模型,检测经典Wnt信号通路特异性抑制剂舒林酸处理后经典Wnt信号通路及氧化应激标志物在孤独症模型大鼠前额叶皮质及海马脑区的表达变化。 Western blotting法检测糖原合成激酶3β( GSK-3β)、β-catenin和4-羟基壬烯醛(4-HNE)表达,半定量RT-PCR法检测硫氧还蛋白(Trx)1和Trx2 mRNA表达。结果:与对照组相比,在前额叶皮质及海马脑区VPA组GSK-3β蛋白表达减少, Trx1和Trx mRNA 表达减少,β-catenin与4-HNE的表达增加;而与VPA组相比,VPA与舒林酸同时处理组GSK-3β的表达显著增加,β-catenin和4-HNE的表达显著减少。结论:舒林酸减少了孤独症发生过程中氧化应激的产生,提示经典Wnt信号通路上调导致氧化应激产生,进而导致孤独症易感性增加。

    • 摘要: 目的:以人胰腺癌细胞系PANC-1为研究对象,利用不同浓度舒林酸处理PANC-1细胞,观察其对PANC-1细胞增殖、凋亡影响,并探讨舒林酸通过抑制Wnt/β-catenin信号通路杀伤PANC-1细胞的可能机制。方法实验分为阴性对照组(加入不含舒林酸的DMSO)和实验组(分别加入舒林酸浓度为0.25、0.5、1、1.5、2 mM的培养液,分别为:阴性对照组、0.25 mM组、0.5 mM组、1.0 mM组、1.5 mM组、2.0 mM组,总计6组)。MTT法检测PANC-1细胞生长抑制率;流式细胞术检测细胞凋亡率;RT-PCR和免疫细胞化学技术检测细胞内β-Catenin的表达。结果 MTT结果显示:PANC-1细胞经舒林酸干预后生长均受到不同程度抑制,且随着舒林酸浓度增加,抑制作用越强。流式细胞术检测凋亡结果显示PANC-1细胞早期凋亡率干预后均有不同程度增加,与对照组相比,0.5、1.0 mM组早期凋亡率差异无统计学意义,而1.5、2.0 mM组差异均有统计学意义(P<0.05)。RT-PCR结果显示可见各组β-catenin mRNA表达量随着舒林酸浓度增加而降低,0.5、1.0 mM组与对照组相比差异无统计学意义,而1.5及2.0 mM组差异有统计学意义(P<0.05);应用2.0 mM的舒林酸处理PANC-1细胞0、12、24、48、72 h,随着处理时间延长,β-catenin mRNA表达量逐渐降低,各处理组与对照组相比,差异有统计学意义(P<0.05)。ICC结果证实干预后PANC-1细胞内β-catenin表达量及核聚集降低,与对照组相比,0.25、0.5 mM组差异无统计学意义,而1.0、1.5、2.0 mM组差异有统计学意义(P<0.05)。结论舒林酸对PANC-1细胞具有生长抑制及促凋亡作用,这种作用具有浓度-时间依赖性,舒林酸抑制Wnt/β-catenin信号通路可能是其杀伤PANC-1细胞的可能机制之一。%Objective To discuss the influence of different concentration sulindac on pancreatic cancer cell line PANC-1 cell proliferation and apoptosis,and investigate the possible mechanism that sulindac can inhibit the Wnt/beta-catenin pathway to kill pancreatic cancer cells. Methods PANC-1 cell were divided into negative control group (added containing no sulindac DMSO)and experimental group (added sulindac with concentrations of 0.25 ,0.5 ,1 ,1.5 ,2 mM medium,respectively,name as 0.25 mM group,0.5 mM group,1.0 mM group,1.5 mM group,2.0 mM group),and treated with different time,cell proliferation inhibition ratio in each group was detected by MTT assay,cell apoptosis ratio was detected by flow cytometry,the expression ofβ-catenin mRNA and protein were detected by RT-PCR and immunocytochemistry.Results MTT results showed that sulindac can inhibit the cell proliferation of PANC-1 by a dose-and time-dependent manner.Cell apoptosis increased after sulindac treatment in different degrees,and there were statistical differences between 1.5,2.0 mMgroup and control groups (P<0.05).RT-PCR results showed that the expression ofβ-catenin mRNA decreased after the treatment of sulindac,there were statistical differences between 1.5,2.0 mMgroup and control group (P<0.05). In the 2.0mM group,the expression ofβ-catenin decreased along with the time extending (P<0.05 ).ICC results showed that sulindac inhibited the expression ofβ-catenin protein and nuclear accumulation,there were no statistical differences in 0.25 ,0.5 mM group and control group,but there were statistical differences in 1.0,1.5,2.0 mMgroup.Conclusion Sulindac could inhibit cell proliferation and facilitate apoptosis of PANC-1,this effect is dose-and time-dependent.The inhibition of Wnt/beta-catenin signal pathway may be a possible mechanism of its cytotoxicity.
