Definitions
- the present invention relates to a DNA construct which contains a cDNA sequence for human poly (ADP-ribose) polymerase, cell lines which contain the DNA construct and a method for identifying DNA-damaging substances on the basis of these cell lines, overexpress the poly (ADP-ribose) polymerase.
- DNA-damaging substances physical and chemical carcinogens
- DNA strand breaks have been measured by measuring the strand breaks either in cell lysates by alkaline DNA denaturation methods (for example “alkali elution") or in situ using single cells ( The so-called “comet assay” was identified.
- alkaline DNA denaturation methods for example "alkali elution”
- in situ using single cells The so-called “comet assay” was identified.
- the lysate tests had the disadvantage of being technically relatively complex and requiring a high level of manual skill on the part of the experimenter Effort required.
- the object of the present invention is therefore to provide a method for the rapid, reliable identification of chemical carcinogens.
- the principle of the present invention is based on the detection of cellular poly (ADP-Ribosel production as an indicator of DNA strand breaks occurring in living cells.
- the poly (ADP-Ribose) is derived from the poly (ADP-Ribose) polymerase ( PARP) is synthesized in the presence of DNA strand breaks and with the consumption of NAD + . This occurs under the influence of carcinogenic substances in almost every nucleated cell.
- manipulation ie by introducing a PARP-DNA sequence into a certain combination with a promoter, particularly a lot of poly (ADP-ribose), and can be formed by suitable measurement methods, for example immunofluorescence, be detected.
- An example of a construct which contains the PARP-DNA sequence is the plasmid PPARP31 deposited with the DSM under the number DSM 9430 on September 13, 1994.
- pPARP 31 can be obtained by the following steps: a) - Ligation of a cDNA which contains the complete open reading frame of the poly (ADP-ribose) polymerase from human embryonic fibroblasts (HEF cells), in pBluescript to obtain the plasmid pPARP 25 (Küpper, dissertation Heidelberg University, 1990). The complete open reading frame of one of the known PARP cDNAs is e.g. published in the GenBank / EMBL database, accession number J 03473 (Kurosaki). b) - Isolation of the Xho / Xba fragment from pPARP25 c) - Production of the eukaryotic expression vector pL15TK
- the 650 bp Hincll / Avall fragment of the human cytomegalovirus promoter / enhancer (HCMV Prom), which has blunted ends, is ligated into the blunted EcoRI site of pUC19, whereby the "intermediate vector" is obtained pL15 becomes.
- the 629 bp Smal / Hindlll fragment of the poly adenylation signal of the herpes simplex virus thymidine kinase gene (TK poly A) is then ligated into the smoothed Sphl site and into the Hind III site of pL15, as a result of which the vector pL15TK is obtained.
- the vector pL15TK contains the resistance gene for ampicillin (Amp), a bacterial replication origin (ori), and parts of the lac operon (Z and i).
- the polylinker cassette from pUC 19 is intact except for the EcoRI and Sphl interfaces.
- the Xbal interfaces of the vector and the insert remain intact.
- the embryonic hamster cell line CO60 (Lavi, PNAS 78, p. 6144 ff (1981)) is stably transfected with a plasmid which expresses a poly (ADP-ribose) polymerase, preferably pPARP 31.
- a poly (ADP-ribose) polymerase preferably pPARP 31.
- the cell clones obtained in the process (in the case of using pPARP31, these cell clones were called COCF1, -2, -4) overexpress the human PARP.
- COCF1, -2, -4 With the same genotoxic treatment (eg.
- the hamster cell clones COCF1, COCF2 and C0CF4 and the control cell line COC-FN1 were deposited with the DSM under the numbers ACC2186, ACC2187, ACC2188 and ACC2189 on September 6, 1994.
- the sensitivity of a detection method for carcinogens that produce DNA strand breaks is significantly increased.
- the cellular synthesis of poly results in a signal amplification, as it were, since a single DNA strand break leads to the synthesis of several or even many polymer molecules which, with up to 200 monomeric building blocks, achieve considerable complexity.
- the polymer synthesis is further increased by transfection of the expression construct containing the PARP sequence, preferably pPARP31.
- the sensitivity of the detection method can be further increased by subjecting the cells to a defined heat shock, for example 30 minutes at 45 ° C., shortly before the action of the test substance, as a result of which the degradation of the poly (ADP-ribose) associated with the Synthesis can compete, is inhibited.
- Evidence of cellular poly (ADP- Ribose) is preferably immunological. This has the advantage that the steps can be carried out easily and the method can be carried out quickly with a time expenditure of a few hours.
- the test is preferably carried out by means of fluorescence microscopy or on microtiter plates, where the specific antibody binding can be evaluated in the sense of an ELISA by automated measurement.
- the cells are lysed after treatment with the DNA-damaging test substance, the lysates are applied to a support, for example a filter membrane, and the poly (ADP-ribose) formed is detected with a poly (ADP-ribose) -specific antibody , which can be enzyme-labeled.
- a poly (ADP-ribose) -specific antibody which can be enzyme-labeled.
- the above antibody may be unlabeled.
- the detection is then carried out by a second antibody directed against the above antibody, which is labeled, for example enzyme-labeled.
- the detection of poly (ADP-ribose) by immunofluorescence is described as an example.
- the cells containing the PARP-DNA construct are left on e.g. Cover glasses or microtiter plates to a normal cell density.
- the cells are treated with a DNA-damaging test substance.
- the treatment time is different for individual test substances. It can easily be determined by a specialist. The treatment time is often 1-15 minutes.
- the cells are then fixed to the support (e.g. cover glass or microtiter plate). After washing the carrier, briefly drying and rehydrating the cells in buffer, incubation is carried out with a first antibody against poly (ADP-Ribose). After washing several times with buffer, the incubation is carried out with a labeled second antibody directed against the first antibody. After repeated washing, the fluorescence microscopic evaluation or detection is carried out in an ELISA reader.
- Suitable DNA-damaging test substances are, for example, radiation, drugs such as cytostatics, UV light, food additives or chemicals such as dyes, solvents or cleaning agents.
- the principle of PARP overexpression described can easily be extended to primary cells from experimental animals by transiently or stably introducing the expression cassette for human PARP into such primary cell cultures with the aid of a viral vector. As a result, cells with the full, tissue-specific foreign substance metabolizing capacity are available. On the one hand, this allows the detection of agents that only damage the DNA after metabolization, on the other hand, an organ-specific damage potential can be estimated with such cells.

- C0CF1 cells were grown on coverslips overnight.
- the cells were treated with 2.8-20 Gray Gamma radiation.
- Five minutes after the start of radiation the cells were fixed in 10% trichloroacetic acid (10 minutes on ice).
- the coverslips were washed in 70%, 90% and absolute ethanol for 3 minutes each.
- After air drying for 1 minute the cells were rehydrated in PBS buffer (phosphate buffered saline) for 1 minute.
- the first antibody was added (cell culture supernatant of the hybridoma 10H [described by Kawamitsu et al., Biochemistry 23, 3771 ff., 1984], which secretes a monoclonal, highly specific antibody against poly (ADP-ribose)) .
- the coverslips were then washed three times for 5 minutes in PBS buffer and the second antibody (FITC-coupled goat anti-mouse immunoglobulins; from Renner, Dannstadt) was added and incubated at 37 ° C. for 30 minutes. Then it was washed again three times for 5 minutes with PBS buffer and the cover slips were embedded in polyvinyl alcohol on slides. The fluorescence microscopic evaluation was carried out.
- the second antibody FITC-coupled goat anti-mouse immunoglobulins
