2肿瘤恶性转化与C/EBPβ和STAT3基因相关(英文)显示文摘The inference of transcriptional networks that regulate transitions into physiological or pathological cellular states remains a central challenge in systems biology. A mesenchymal phenotype is the hallmark of tumour aggressiveness in human malignant glioma,but the regulatory programs responsible for implementing the associated molecular signature are largely unknown. Here we show that reverse-engineering and an unbiased interrogation of a glioma-specific regulatory network reveal the transcriptional module that activates expression of mesenchymal genes in malignant glioma. Two transcription factors (C/EBPβ and STAT3) emerge as synergistic initiators and master regulators of mesenchymal transformation. Ectopic co-expression of C/EBPβ and STAT3 reprograms neural stem cells along the aberrant mesenchymal lineage,whereas elimination of the two factors in glioma cells leads to collapse of the mesenchymal signature and reduces tumour aggressiveness. In human glioma,expression of C/EBPβ and STAT3 correlates with mesenchymal differentiation and predicts poor clinical outcome. These results show that the activation of a small regulatory module is necessary and sufficient to initiate and maintain an aberrant phenotypic state in cancer cells.Maria Stella Carro Wei Keat Lim Mariano Javier Alvarez Robert J.

3胶质瘤干细胞对替莫唑胺敏感性的研究显示文摘目的探讨胶质瘤干细胞(GSC)对替莫唑胺(TMZ)的敏感性及耐药机制。方法新鲜多形性胶质母细胞瘤(GBM)标本培养后获得GSC。免疫荧光技术检测未分化GSC的CD133及分化生长GSC的GFAP的表达,MTS法检测对替莫唑胺的敏感性,流式细胞技术对CD133阳性细胞的比例进行定量,荧光标记的甲基化特异性PCR分析MGMT启动子区域的甲基化状态,Western blot检测抑癌基因PTEN的表达。结果(1)5例GBM标本中成功获得GSC,符合肿瘤干细胞定义。(2)5个GSC细胞株多数对TMZ不敏感。其中,T509的半数抑制浓度(IC50)为22.3μmol/L(敏感),T411的IC50为286.3μmol/L(中度敏感),其余3个细胞株T402,T405及T509的IC50皆大于1000μmol/L(不敏感)。(3)CD133阳性细胞比例大于10%的GSC细胞株对TMZ不敏感。(4)MGMT启动子区域呈去甲基化状态的GSC对TMZ不敏感或仅为中度敏感。(5)5个GSC细胞株中,PTEN表达水平差异大,与GSC对TMZ的敏感性无明显关联。结论GSC对TMZ普遍耐药,与MGMT启动子区域甲基化状态及CD133阳性细胞有关,而与PTEN蛋白表达水平无明显关联。赛克 WANG Shu-zhen Popoff S Yung WK Colman H 陈忠平 2009中华神经外科杂志2009,25,10:7
4新型STAT3信号转导通路抑制剂WP1193在体外对脑肿瘤干细胞生物学特性影响的研究显示文摘背景与目的:恶性脑胶质母细胞瘤(glioblastoma Multiforme,GBM)是最常见的成人原发性脑肿瘤,预后仍不理想。近年来,肿瘤干细胞理论认为脑肿瘤干细胞是GBM进展及治疗耐受的主要原因,只有针对脑肿瘤干细胞的靶向治疗才能更加有效的治疗GBM。本研究旨在探讨新型STAT3信号转导通路抑制剂WP1193在体外对脑肿瘤干细胞生物学特性的影响。方法:从新鲜手术切除的GBM标本中,分离、培养及鉴定脑肿瘤干细胞。采用Western blot及RT-PCR法检测WP1193给药后,STAT3信号转导通路的变化。使用神经球形成实验评估WP1193对GBM干细胞形成神经球能力的影响。利用RT-PCR及流式细胞技术检测WP1193对CD133阳性细胞的影响。采用MTS及PI染色结合流式细胞技术检测WP1193对GBM干细胞增殖及细胞周期的影响。采用AnnexinV流式细胞术分析WP1193对GBM干细胞的凋亡诱导效应。结果:WP1193抑制GBM干细胞STAT3磷酸化及下游基因的表达。WP1193有效抑制GBM干细胞形成神经球的能力及增殖,并可将细胞阻滞于G1期。WP1193在体外通过改变Bax/Bcl-2比例诱导GBM干细胞凋亡。结论:WP1193通过抑制STAT3信号转导通路,有效的抑制GBM干细胞的增殖及形成神经球的能力,并能诱导凋亡。STAT3信号转导通路可作为GBM干细胞的治疗靶点。赛克 WK Alfred Yung Fred Lang Waldemar Priebe Howard Colman 陈忠平 2009中国神经肿瘤杂志2009,7,3:3
5STAT3信号转导通路抑制剂诱导胶质瘤干细胞产生自噬的研究显示文摘背景与目的:胶质瘤干细胞(glioma stem cell,GSC)在胶质瘤发展及治疗抗拒中发挥重要作用。我们以往的研究表明,新型STAT3信号转导通路抑制剂(STAT3 inhibitor,STI)WP1193能够诱导GSC产生细胞周期阻滞及凋亡。本研究旨在探讨STI是否能在体外诱导GSC产生自噬现象。方法:从手术切除的胶质母细胞瘤中分离及培养GSC。使用STI处理GSC。利用细胞计数法检测STI对GSC增殖的影响。使用Western blot检测自噬相关蛋白LC3的表达情况。吖啶橙染色后,利用荧光显微镜及流式细胞技术检测酸性自噬小体。使用透射电镜检测GSC中自噬小体。结果:STI剂量依赖性的抑制GSC的增殖。STI处理后,GSC中出现LC3表达的切换。STI处理后,GSC中出现自噬小体,且出现自噬小体细胞的比例增加。结论:STI能够在GSC中诱导自噬现象的产生。自噬在STI治疗中的意义及调节机制需要进一步的研究。赛克 WK Alfred Yung Howard Colman Waldemar Priebe 陈忠平 2011中国神经肿瘤杂志2011,9,2:2

8农业贸易条件:问题与启示显示文摘本文集中讨论了农业贸易条件变化问题。对二十多年来国际上对农业贸易条件趋于恶化的研究进行文献分析表明学者观点并不一致;如果加入产品品质改进因素或者与服务业价格进行比较则表明农业贸易条件并未恶化(下降);能源价格与农产品价格间应该存在内在联动关系;在资源约束既定情况下农业贸易条件可能会相对得到改善。David Colman 金铃 2009农业经济问题2009,30,11:2
