The present invention provides binding moieties for CEA, which have a variety of uses wherever detecting, isolating or localizing CEA, and particularly CEA as opposed to cross-reactive antigens such as NCA, is advantageous. Particularly disclosed are synthetic, isolated polypeptides capable of binding CEA, which is overexpressed in adenocarcinomas of endodermally derived digestive system epithelia and fetal colon. Such polypeptides and disclosed derivatives are useful, e. g. , as imaging agents for CEA-expressing tumors.
Evidence demonstrating that elevated expression of dUTPase protects breast cancer cells from the expansion of the intracellular uracil pool, translating to reduced growth inhibition following treatment with 5-FU is provided. The implementation of in silica drug development techniques to identify and develop small molecule inhibitors of dUTPase are reported. As 5-FU and the oral 5-FU pro-drug capecitabine remain central agents in the treatment of a variety of malignancies, the clinical utility of a small molecule inhibitor to dUTPase represents a viable strategy to improve the clinical efficacy of these mainstay chemotherapeutic agents.

Abstract:
The inventors have developed a rapid and sensitive fluorescence-based assay to quantify dNTPs. This assay relies on the principle that incorporation of a limiting dNTP is required for primer-extension and polymerase-mediated 5-3′ exonuclease hydrolysis of a quenched fluorophore-labeled probe resulting in fluorescence. The concentration of limiting dNTPs is directly proportional to the fluorescence generated. This assay has important applications in research that investigates the influence of pathological conditions or pharmacological agents on dNTP biosynthesis and regulation.
