    Biotin-labeled abscisic acid as a probe for investigating abscisic acid binding sites on plasma membranes of barley aleurone protoplasts
    摘要:
    Plant hormone abscisic acid (ABA) plays important roles in dormancy and stress responses, but its binding sites have not yet been fully elucidated. In this report, we suggest the utility of biotin-labeled abscisic acid (bioABA) as a probe to investigate ABA-binding sites on the plasma membrane of barley aleurone protoplasts. BioABA was approximately 100 times less effective than ABA in inhibiting expression of gibberellin-inducible alpha-amylase and in inducing expression of a reporter gene fused to the dehydrin promoter. To ascertain that bioABA could bind to ABA-binding sites on the plasma membrane, we used fluorescence flow cytometry to measure the fluorescence intensity of aleurone protoplasts treated with a combination of bioABA and fluorescence-labeled streptavidin. Addition of bioABA increased the fluorescence of aleurone protoplasts in a concentration-dependent manner, but addition of non-active bioABA derivatives did not. Furthermore, the increase in fluorescence intensity observed upon addition of bioABA was eliminated by co-treatment with excess ABA, but it was not eliminated by co-treatment with other plant hormones. These results suggest that bioABA binds to ABA-binding sites, and that bioABA should be a valuable probe for investigating ABA-binding sites on the plasma membrane. (c) 2005 Elsevier Ltd.

    用于探测Nur77蛋白诱导途径的生物素化强心苷的设计与合成。
    摘要:
    孤儿核受体Nur77(也称为TR3或神经生长因子诱导的克隆B NGFI-B)在调节靶基因表达中起核转录因子的作用,并且在分化,增殖,凋亡,和许多不同细胞类型的存活率 最近的研究表明,Nur77还涉及许多重要的生理和病理过程,包括癌症,炎症和免疫力,心血管疾病和骨骼疾病。我们以前的研究表明强心苷可以诱导Nur77蛋白的表达及其从细胞核到细胞质的转运,然后靶向线粒体,从而导致癌细胞凋亡。为了探测Nur77蛋白的诱导途径,我们设计并合成了一系列新型的生物素化的强心苷,它们分别来自β-安提香和α-安提香,这是两种来自安提阿里斯毒株的典型强心苷。评价了这些生物素化强心苷Nur77蛋白表达的诱导及其对NIH-H460癌细胞增殖的抑制作用。结果表明,一些生物素化的强心苷可以显着诱导Nur77蛋白的表达,与它们的母体化合物β-Antiarin和α-Antiarin相当。而且,评估了它们的抗生蛋白链菌素结合

    albumin (BSA) was accomplished by dialkyl squarate coupling to lysine residues resulting in a library of defined multivalent neo-glycoproteins. Solid-phase binding assays with immobilized neo-glycoproteins revealed distinct affinity and specificity of the multivalent glycan epitopes for Gal-3 binding.

    Galectin-3(Gal-3)是β-半乳糖苷结合凝集素家族的成员,是一种肿瘤生物标志物,参与肿瘤血管生成和转移。因此,Gal-3被认为是早期癌症诊断和抗癌治疗的有希望的靶标。我们在这里提出了定制的多价新糖蛋白文库的合成,并评估了它们的Gal-3结合特性。通过结合使用糖基转移酶和化学酶促反应,我们首先合成了一组N-乙酰基乳糖胺(Galβ1,4GlcNAc; LacNAc 2型)为基础的寡糖,分别具有五个不同的终止糖基化表位。牛血清白蛋白(BSA)的新糖基化是通过将二烷基方酸与赖氨酸残基偶联而完成的,从而形成一个确定的多价新糖蛋白文库。固定化的新糖蛋白的固相结合测定显示了多价聚糖表位对Gal-3结合的独特亲和力和特异性。特别是,用N ',N修饰的新糖蛋白″-二乙酰基乳糖胺(GalNAcβ1,4GlcNAc; LacdiNAc)表位显示出高选择性,并被证明可以高亲和力从人血清中捕获Gal-3
