    • In accordance with the present invention, it has been discovered that PPARnull is expressed consistently in tissues associated with each of a variety of disease states which result from neoplastic cell proliferation. It has further been discovered that maximal activation of PPARnull with exogenous ligand promotes terminal differentiation of primary cells which are otherwise subject to neoplastic cell proliferation. In accordance with another aspect of the invention, it has been discovered that RXR-specific ligands are also potent agents for induction of differentiation of cells expressing the PPARnull/RXRnull heterodimer, and that simultaneous treatment of cells subject to neoplastic cell proliferation with a PPARnull-selective ligand, in combination with an RXR-specific ligand, results in an additive stimulation of differentiation. Thus, the effect of neoplastic cell proliferation can be ameliorated by treatment of cells undergoing neoplastic cell proliferation with PPARnull agonists, optionally in the further presence of RXR agonists, thereby blocking further proliferation thereof. Accordingly, compounds and compositions which are useful for the treatment of a variety of disease states which result from neoplastic cell proliferation have been identified and are described herein.
    • 根据本发明,已经发现,PPARγ在与由肿瘤细胞增殖引起的各种疾病状态中的每一种相关的组织中一致地表达。 进一步发现,具有外源性配体的PPARγ的最大活化促进了另外受到肿瘤细胞增殖的原代细胞的终末分化。 根据本发明的另一方面,已经发现RXR特异性配体也是用于诱导表达PPARγ/RXRα异源二聚体的细胞分化的有效试剂,并且用PPARγ- 选择性配体与RXR特异性配体组合导致分化的加性刺激。 因此,可以通过用PPARγ激动剂处理经历赘生性细胞增殖的细胞,任选地在RXR激动剂的进一步存在下,可以改善肿瘤细胞增殖的作用,从而阻断其进一步增殖。 因此,已经鉴定并描述了可用于治疗由肿瘤细胞增殖引起的各种疾病状态的化合物和组合物。

    • A gene activation/inactivation and site-specific integration system has been developed for mammalian cells. The invention system is based on the recombination of transfected sequences by FLP, a recombinase derived from Saccharomyces. In several cell lines, FLP has been shown to rapidly and precisely recombine copies of its specific target sequence. For example, a chromosomally integrated, silent null-galactosidase reporter gene was activated for expression by FLP-mediated removal of intervening sequences to generate clones of marked cells. Alternatively, the reverse reaction can be used to target transfected DNA to specific chromosomal sites. These results demonstrate that FLP can be used, for example, to mosaically activate or inactivate transgenes for a variety of therapeutic purposes, as well as for analysis of vertebrate development. The FLP recombination system of the present invention can be incorporated in transgenic, non-human mammals to achieve site-specific integration of transgenes, to construct functional genes or to disrupt existing genes.
    • 已经为哺乳动物细胞开发了基因激活/失活和位点特异性整合系统。 本发明系统基于通过FLP转染的序列的重组,其是衍生自酵母属的重组酶。 在几种细胞系中,已经显示FLP快速且精确地重组其特异性靶序列的拷贝。 例如,染色体整合的沉默的β-半乳糖苷酶报道基因通过FLP介导的中间序列的去除被激活用于表达以产生标记细胞的克隆。 或者,反向反应可用于将转染的DNA靶向特定的染色体位点。 这些结果表明,FLP可以用于例如用于各种治疗目的的马赛克激活或灭活转基因,以及用于脊椎动物发育的分析。 本发明的FLP重组系统可并入转基因非人哺乳动物中,以实现转基因的位点特异性整合,构建功能基因或破坏现有基因。
