Patent number: 7439032Abstract: Cdc25A is herein identified as a substrate for ?-TrCP1- or ?-TrCP2-mediated ubiquitination and subsequent degradation via the ubiquitin-proteasome pathway. In particular, it has been found that interfering with ?-TrCP expression or function, or increasing ?-TrCP degradation, leads to accumulation of Cdc25A in a cell. Since degradation of Cdc25A is a key feature of the response to DNA damage, leading to a stall in the cell cycle during which the cell can repair the damage, Cdc25A accumulation can abolish this response, thereby sensitizing the cell to DNA damage. Described herein are assays for identifying ?-TrCP inhibitors, and method of using such inhibitors for modulating Cdc25A degradation, sensitization of tumor cells, and as adjuvants in cancer therapy based on DNA damaging agents.Type: GrantFiled: October 18, 2004Date of Patent: October 21, 2008Assignee: New York UniversityInventor: Michele Pagano

Patent number: 7439035Abstract: The invention relates to a substrate and method for the assay of ribonuclease H activity. The substrate comprises a DNA/RNA heteroduplex molecule having fluorophore and quencher molecules in close proximity, which emit a background level of fluorescence in the absence of ribonuclease H activity due to quenching of the fluorophore as a result of fluorescence resonance energy transfer. Ribonuclease H cleavage of the heteroduplex results in an increase in fluorescence emission due to the destabilization and separation of the DNA and RNA molecules and their associated fluorophore and quencher molecules. The assay method of the present invention is suitable for use in screening (e.g. high throughput screening) for modulators, e.g. inhibitors, of the ribonuclease H activity associated with, for example, reverse transcriptase and ribonuclease H enzymes.Type: GrantFiled: January 24, 2007Date of Patent: October 21, 2008Assignee: McGill UniversityInventors: Michael A.
