  • Publication number: 20100279947
    Abstract: Phosphorylated Apoptin is described. Apoptin is tumor-specifically phosphorylated and part of the Apoptin apoptotic pathway in tumor cells is elucidated. New therapeutic possibilities, for example, novel therapeutic compounds that can work alone or, sequentially to, or jointly with other known compounds. Also, the use of tumor-specifically phosphorylation of Apoptin for diagnostic purposes is described. Such a diagnostic purpose can, for example, be a method for detecting the presence of cancer cells or cells that are cancer prone or a method to identify a putative cancer inducing agent or a method for the in vitro treatment effect of Apoptin on tumor cells by testing the phosphorylation state of Apoptin. Even more, the invention provides possibilities to further elucidate the apoptotic pathway and to identify for example crucial mediators of phosphorylation in human tumor cells. Interfering with such a mediator could provide new anti-cancer therapies.

  • Patent number: 7427658
    Abstract: The coding information for three putative chicken anemia virus proteins (VP1, VP2, VP3) was inserted into a baculovirus vector and expressed in insect cells. Only lysates of insect cells which have synthesized equivalent amounts of all three recombinant CAV proteins or cells which synthesized mainly VP1 plus VP2 induced neutralizing antibodies directed against CAV in inoculated chickens. Progeny of those chickens were protected against clinical disease after CAV challenge. Inoculation of a mixture of lysates of cells that were separately infected with VP1-, VP2- and VP3-recombinant baculovirus did not induce significant levels of neutralizing antibody directed against CAV and their progeny were not protected against CAV challenge. Expression in the same cell of at least VP1 plus VP2 is required to obtain sufficient protection in chickens. Therefore, recombinant CAV proteins produced by baculovirus vectors can be used as a sub-unit vaccine against CAV infections.

  • Patent number: 7253150
    Abstract: The invention relates to gene delivery vehicles which comprise nucleic acid molecules encoding apoptosis-inducing proteins VP2 and/or apoptin (VP3) like activity. VP2 and VP3 are viral proteins of the Chicken Anaemia Virus. Also, the invention relates to anti-tumor therapies. Infection of various human tumor cells with the gene delivery vehicles of the invention will result in the induction of apoptosis in tumor cells and much reduced apoptosis, if at all, in normal diploid, non-transformed/non-malignant cells.

  • Patent number: 6528247
    Abstract: The invention related to activation of apoptin-induced apoptosis by different cell-transforming agents in normal and or cancer-prone cells. Apoptin, also called VP3, is a viral protein derived from the Chicken anemia virus. Also the invention related to preventive anti-tumor therapies of normal and/or cancer-prone cells. Treatment of normal and/or cancer prone cells with tumor-inducing agents will activate apoptin-induced apoptosis, resulting in the elimination of potential tumor cells. Also the invention relates to diagnosis of cancer agents. Agents with tumor activity can be examined by expressing them in normal cells and analyzing their capability of enabling apoptin-induced apoptosis.

  • Patent number: 6162461
    Abstract: The coding information for three putative chicken anemia virus proteins (VP1, VP2, VP3) was inserted into a baculovirus vector and expressed in insect cells. The immunogenic properties of the chicken anemia virus (CAV) proteins produced separately or together in insect-cell cultures were analyzed by inoculating them into chickens. Only lysates of insect cells which have synthesized equivalent amounts of all three recombinant CAV proteins or cells which synthesized mainly VP1 plus VP2 induced neutralizing antibodies directed against CAV in inoculated chickens. Progeny of those chickens were protected against clinical disease after CAV challenge. Inoculation of a mixture of lysates of cells that were separately infected with VP1-, VP2- and VP3-recombinant baculovirus did not induce significant levels of neutralizing antibody directed against CAV and their progeny were not protected against CAV challenge.

  • Patent number: 5981502
    Abstract: Novel proteins of the Chicken Anemia Virus are described and compositions for preventing or treating infections with that virus (CAV), in particular vaccines less pathogenic than the CAV itself, but yet leading to neutralizing antibodies in the immunized animal. Besides, there are described compositions containing antibodies against parts of the CAV for the control of infections with CAV and anti-idiotype antibodies. The invention also provides antibodies and test kits for the detection of CAV. Recombinant DNA molecules derived from CAV and host cells transfected therewith and vaccines based on these host cells are made possible by this invention. The invention also comprises living virus vaccines in which apiece of DAN is brought into a virus infectious to the host. Besides, the Invention provides uses of proteins of CAV in the induction of apoptosis, in particular in tumor cells. It further provides the induction of cell death by means of gene therapy.
