    摘要:三种结构相关的特定类似激素类衍生物,即14-去氧-8(14)-烯类20-羟基脱氧雄甾酮的7,7'-二聚体,通过光化学转化得到,分别为20-羟基脱氧雄甾酮,波纳斯特龙a和阿苏龙c.二聚体激素的结构主要通过核磁共振光谱学鉴定,辅以质谱和红外光谱.二聚体生成产物的收率取决于反应物浓度和光反应条件.惰性气氛支持高产率,而氧气氛完全阻止了二聚体的形成.与相关原始激素相比,在果蝇bii生物检测中,这三种二聚体保留了相当高的激素受体激动活性.

    权利人:GENERATION BIO CO
    摘要:The present application discloses methods for synthetic production and cell-free synthesis of DNA vectors, particularly closed-ended linear DNA vectors having one or more gaps (e.g., nicked ceDNA vectors, “neDNAâ€?) and adenoassociated-virus (AAV) vector which is single strand DNA having linear and continuous structure, for delivery and expression of a transgene in the host cell. The present invention also relates to an in vitro process for production of closed-ended DNA vectors, corresponding DNA vector products produced by the methods and uses thereof, and oligonucleotides and kits useful in the process of the present invention.

    标题:Method of inducing apoptosis in lymphoid cells
    发明人:GREEN MICHAEL R; DEVIREDDY LAXMINARAYANA; TEODORO JOSE G; RICHARD FABIAN
    权利人:UNIV MASSACHUSETTS
    摘要:A two-stage, transcriptionally regulated apoptotic program has been discovered. In the first stage, IL-3 withdrawal results in transcriptional activation of the NGAL gene followed by synthesis and secretion of NGAL protein. In the second stage, secreted NGAL protein induces apoptosis in lymphoid cells by an autocrine mechanism. Based on this discovery, the invention provides a method of inducing apoptosis in a lymphoid cell in a mammal, e.g., a human patient. The invention includes administering a therapeutically effective amount of an NGAL polypeptide or NGAL-like polypeptide to a mammal.

    标 题:Induction of apoptosis and cell growth inhibition by protein 4.33
    发明人:OH YOUNGMAN; ROSENFELD RON; INGERMANN ANGELA RENAE
    权利人:UNIV OREGON HEALTH & SCIENCE
    摘要:There is disclosed an isolated cDNA sequence (SEQ ID NO:1) encoding a P4.33 polypeptide and comprising a coding region (SEQ ID NO:2) of the sequence described in SEQ ID NO:1, or a sequence having at least 90% homology with the coding region of SEQ ID NO:1. The P4.33 polypeptide functions as a specific cell-surface receptor for IGFBP-3, and undergoes nuclear translocation in combination with IGFBP-3. IGFBP-3 and P4.33 (IGFBP-3R) cooperatively suppress DNA synthesis and cell growth, and induce caspase activation and apoptosis in cancer cells, indicating that P4.33 is an important mediator of IGF-independent growth inhibitory actions of IGFBP-3. The P4.33:IGFBP-3 system of the present invention can be used, inter alia, in screening and diagnostic assays, and for therapeutic methods for cancer treatment and tumor suppression.
