    摘要: Described is a conjugate comprising (a) an amphiphilic transport peptide of human origin as a transmembrane module (TPU), (b) a nuclear localization sequence (NLS) and (c) a signalling and/or drug carrying module (SM), preferably comprising Gd, Ga, Fe, Mn, I and/or F as (diagnostic) image creating compound. Said conjugate is useful for diagnostic purposes, e.g., for cell tracking by MRI, as a contrast agent (e.g., replacing a "biopsy clip") for MRI, or for determining the activity of DNA repair enzymes by MRI. Said conjugate is also useful for therapy, e.g., for chemotherapy or intranuclear Gadolinium Neutron Capture Therapy (GNCT).
    The transmembrane module (TPU) is selected among peptides of human origin, whose amino acid sequences are similar to the sequence of the antennapedia fragment RQIKIWFQNRRMKWKK. In a specific embodiment, TPU is derived from the human homeobox protein HOX-B1. The nuclear localization sequence (NLS) is derived from the simian virus 40-T antigen or from a transcription factor.

    摘要: The present invention therefore provides a screening method for the identification and characterization of inhibitors of DNA methyltransferases comprising the following steps:

    a) generation of at least one Drosophila culture

    which culture comprises at least one offspring that is derived from a cross between flies of the Drosophila strains GawB(69B) and UAS-Dnmt3a and in an appropriate developmental stage,
    a sufficient amount of Drosophila medium
    and an appropriate concentration of at least one candidate compound for a DNA methyltransferase inhibitor,

    b) incubation of the the Drosophila culture of step a) under incubation conditions which allow normal Drosophila development for an appropriate incubation period,
    c) identification of those Drosophila cultures of step b) that show the presence of mobile larvae or pupae.

    In another aspect, the invention concerns the offsprings derived from a cross between the transgenic Drosophila strains GawB(69B) and UAS-Dnmt3a , as well as their use for the identification and characterization of inhibitors of DNA methyltransferases, particularly of inhibitors of Dnmt3a.

    摘要: The invention relates to a cage rack system (1) with forced ventilation. Each cage (2) in said system is connected to a ventilation unit (3) which is configured in such a way that the cages (2) can be flushed for ventilation in a low pressure mode or an overpressure mode. The aim of the invention is to provide a cage rack system (1) of this type that is more simple, more economical and more easy to handle and transport and which has a high level of operational reliability. To this end, the ventilation unit (3) has only one pump (4) with a drive (5) and is configured in such a way that a conveying direction (6 or 7) can be adjusted to or from the cages (2).

    摘要: The present invention relates to the identification and use of target genes for the detection and treatment of drug-resistant tumor cells. The nucleic acids of the present invention exhibit a deregulated phenotype when the tumor cells are subjected to cytostatic drugs, i.e. they are expressed in a higher or lower amount as compared to parental drug-sensitive cancer cells. Thus, they can be used as a diagnostic and pharmaceutical tool to render drug-resistant cells drug-sensitive. In addition, the present invention includes the polypeptides encoded by the respective nucleic acids, expression vectors harboring the nucleic acids, host cells for expression and methods for the diagnosis and treatment of drug-resistant tumor cells.
