  • Patent number: 6350464
    Abstract: Biodegradable polymer compositions suitable for intraperitoneal administration to treat a mammalian subject having ovarian cancer are described, wherein the polymer compositions provide extended release of the antineoplastic agent into the peritoneum of the subject. The subject compositions can increase the median survival rate from the cancer by at least about 10%, as compared with the median survival rate obtained by administration of a composition comprising the same dosage of the antineoplastic agent without the biodegradable polymer. Solid articles and methods for treating ovarian cancer are also described.

  • Patent number: 6303310
    Abstract: A method and a kit for detecting interactions between three or more proteins, in vivo, using reconstitution of the activity of a transcriptional activator is provided. Reconstitution of the transcriptional activator makes use of chimeric genes which express hybrid proteins. In one embodiment, three types of hybrid proteins are prepared. The first hybrid contains the DNA-binding domain of a transcriptional activator fused to the first test protein. The second hybrid protein contains a transcriptional activation domain fused to the second test protein. The third hybrid protein contains a nuclear localization peptide fused to a third test protein and mediates assembly of the three-protein complex involving the three hybrids. If the three test proteins are able to interact, they bring into close proximity the two domains of the transcriptional activator.
