  • Patent number: 8043815
    Abstract: Provided are methods for determining whether an individual is a candidate to receive treatment with a DNA methylation inhibitor. The method can be performed a biological sample of cancerous tissue of the individual. Determining that PDEF expression is absent or low and survivin expression is present identifies the individual as a candidate to receive a treatment with a DNA methylation inhibitor. The method also includes communicating the result of identifying an individual as a candidate for receiving a DNA methylation inhibitor to a health care provider.

  • Patent number: 7968708
    Abstract: Disclosed are compounds having the formula: wherein Z1 is an alkylene moiety; Q is a carboxylic acid derivative; and R1 and R2 are the same or different and are selected from the group consisting of alkyl, aryl, alkylcarbonyl, arylcarbonyl, hydroxycarbonyl, and alkoxycarbonyl or R1 and R2, taken together with the nitrogen atom to which they are bound, form a ring. Also disclosed are compounds having the formula: wherein Z1 is an alkylene moiety; Q is a carboxylic acid derivative; and R13 is selected from the group consisting of alkyl and aryl. The compounds can be used to modulate cell proliferation and/or apoptosis, for example, in the treatment of cancers and other proliferative diseases, disorders, and conditions.

  • Patent number: 7569221
    Abstract: Provided are compositions and methods for identifying agents that can modulate expression of the human survivin gene. The compositions include eukaryotic cells that contain a human survivin promoter sequence operably linked to a reporter gene. The method comprises determining whether a test agent can modulate transcription from a human survivin promoter sequence by adding a test agent to eukaryotic containing a human survivin promoter sequence operably linked to a reporter gene, measuring expression of the reporter gene and comparing expression of the reporter gene from to a control, wherein an increase or decrease of expression of the reporter gene relative to the control is indicative that the test agent can modulate transcription from a human survivin promoter. The method also comprises the use of SPlucTg mice for preclinical drug identification, including testing of candidate drug toxicity and efficacy.
