    • The present invention relates to a pharmaceutical composition, including inhibitors for expression or activity of TIP41 protein, for prevention and treatment of cancer. When the liver cancer cell lines, showing resistance to TRAIL, are treated with TIP41 siRNA and TRAIL, apoptosis is induced in cancer cell. The same effect is found in cases of lung cancer and colon cancer with resistance against TRAIL. Moreover, this induction of apoptosis by TIP41 siRNA and TRAIL was confirmed in tumor xenograft, which was injected with Huh7 liver cancer cells and then was subjected to TIP41 siRNA transfection and TRAIL treatment. In addition, it was confirmed through animal experiments in which the tumor size has reduced and apoptosis was induced by treatment with TIP41 siRNA and TRAIL. Of note, MKK7/JNK pathway was confirmed to mediate the apoptosis induced by the application of TIP41 siRNA and TRAIL. The apoptosis were verified to be caused by the activation of MKK7/JNK signaling pathway. Taken together, the present invention provide the strong evidence that the pharmaceutical composition, including inhibitors for TIP41 expression or activity can be used for cancer prevention and treatment as well as an anti-cancer adjuvant. Taken together, the pharmaceutical composition comprising inhibitors for expression or activity of TIP41 protein may be used for prevention and treatment of cancer or as an anti-cancer adjuvant.
    • 本发明涉及包含用于预防和治疗癌症的TIP41蛋白表达或活性抑制剂的药物组合物。 当显示对TRAIL的抗性的肝癌细胞系用TIP41 siRNA和TRAIL处理时,在癌细胞中诱导细胞凋亡。 在具有抗TRAIL的肺癌和结肠癌的情况下也发现了相同的效果。 此外,在注射Huh7肝癌细胞的肿瘤异种移植物中证实了TIP41 siRNA和TRAIL的这种诱导凋亡,然后进行TIP41 siRNA转染和TRAIL处理。 此外,通过用TIP41 siRNA和TRAIL处理诱导肿瘤大小减少并诱导细胞凋亡的动物实验证实。 值得注意的是,MKK7 / JNK途径被证实可以介导应用TIP41 siRNA和TRAIL诱导的细胞凋亡。 验证细胞凋亡是由MKK7 / JNK信号通路的激活引起的。 综合起来,本发明提供了强有力的证据,包括用于TIP41表达或活性的抑制剂的药物组合物可用于癌症预防和治疗以及抗癌辅助剂。 总之,包含TIP41蛋白表达或活性抑制剂的药物组合物可用于预防和治疗癌症或作为抗癌辅助剂。

    • An organic electroluminescent (EL) polymer for a light emitting diode in accordance with the present invention is PDPCVz which is prepared by combining a dialkyl substituted phenylene moiety and a carbazole moiety. Another organic EL polymer is PPOPPD which is prepared by combining an oxadiazole moiety and a phenylene moiety. In the present invention, a polymer blend of said PDPCVz and PPDPPO is used for an organic EL polymer. The organic EL polymer according to the present invention is applied to a light emitting layer of a light emitting diode having a cathode/light emitting layer/anode structure, a cathode/buffer layer/light emitting layer/anode structure, or a cathode/hole transporting layer/light emitting layer/electron transporting layer/anode structure. Each of said PDPCVz and PPDPPO can be blended with conventional polymers such as polystyrene, polycarbonate, polyacrylate, polymethylmethacrylate, polyvinylcarbazole, polyimide, liquid crystalline polymer, etc. The EL polymers according to the present invention can be blended with a lower molecular fluorescent dye.
