    • The present invention provides cell permeable NF-κB inhibitors consist of a polypeptide derived from the p65 subunit of NF-κB and a protein transduction domain derived from antennapedia third helix sequence. The inhibitor suppressed NF-κB activation induced by TNF, LPS, IL-1, okadaic acid, PMA, H2O2 and cigarette smoke condensate. NF-κB-regulated reporter gene expression induced by TNF, TNFR1, TRADD, TRAF2, NIK, IKK and p65 was suppressed by the inhibitor. The inhibitor enhanced TNF- and chemotherapeutic agent-induced apoptosis. Overall these results demonstrate a NF-κB inhibitor that can selectively inhibit NF-κB activation induced by various inflammatory stimuli, downregulate NF-κB mediated gene expression and upregulate apoptosis.
    • 本发明提供由NF-κB的p65亚基衍生的多肽和来自触角二极体第三螺旋序列的蛋白质转导结构域的细胞渗透性NF-κB抑制剂。 抑制剂抑制由TNF,LPS,IL-1,冈田酸,PMA,H 2 O 2 O 2和香烟烟雾冷凝物诱导的NF-κB活化。 由TNF,TNFR1,TRADD,TRAF2,NIK,IKK和p65诱导的NF-κB调节的报告基因表达被抑制剂抑制。 该抑制剂增强了TNF-和化学治疗剂诱导的细胞凋亡。 总体上,这些结果表明可以选择性地抑制由各种炎性刺激诱导的NF-κB活化,下调NF-κB介导的基因表达和上调细胞凋亡的NF-κB抑制剂。

    • All multiple myeloma cell lines examined showed constitutively active IκB kinase (IKK), IκBα phosphorylation and constitutively active NF-κB. Curcumin, a chemopreventive agent, suppressed constitutive IκBα phosphorylation through inhibition of IKK activity and downregulated NF-κB. Curcumin also downregulated expression of NF-κB-regulated gene products such as IκBα, Bcl-2, Bcl-xL, cyclin D1 and interleukin-6. Consequently, curcumin suppressed multiple myeloma cell proliferation and arrested cells at the G1/S phase of the cell cycle. Curcumin also induced apoptosis and chemosensitivity to vincristine. Overall, results presented herein provide a molecular basis for the treatment of multiple myeloma patients with this pharmacologically safe agent.
    • 检查的所有多发性骨髓瘤细胞系显示组成型活性IkappaB激酶(IKK),IkappaBalpha磷酸化和组成型活性NF-κB。 姜黄素是化学预防药物,通过抑制IKK活性和下调NF-κB来抑制组成型IkappaBalpha磷酸化。 姜黄素也下调NF-κB调节的基因产物如IkappaBalpha,Bcl-2,Bcl-xL细胞周期蛋白D1和白细胞介素-6的表达。 因此,姜黄素在细胞周期的G1 / S期抑制多发性骨髓瘤细胞增殖和阻滞细胞。 姜黄素还诱导长春新碱的凋亡和化学敏感性。 总体而言,本文提供的结果提供了用该药物安全剂治疗多发性骨髓瘤患者的分子基础。
