Abstract: The present invention relates to an antibody specifically binding the carboxymethylated catalytic subunit of protein phosphatase 2A (PP2Ac). Also provided are diagnostic uses of said antibody and screening methods employing the inventive antibody.

Abstract: The present invention relates to methods and biomarkers for detection and characterization of conditions associated with aberrant function of the PPP2R1A subunit of the PP2A protein (e.g., high grade subtypes of uterine cancer) in biological samples (e.g., tissue samples, blood samples, plasma samples, cell samples, serum samples), and related methods of treatment. In particular, the present invention provides compositions and methods for characterizing a patient as having such a condition by identifying mutations in the PPP2R1A subunit of the PP2A gene or gene products, and related methods of treatment through administering to such a patient a DNA Damage Response Pathway (DDR) modulating agent (e.g., a ribonucleotide reductase inhibitor).

Abstract: Disclosed herein are methods and compositions for performing assays for determining efficacy of drugs using rat SCID models that exhibit excellent take rates, and excellent tumor growth rates. The methods and compositions offer dramatically improved efficiencies compared to corresponding mouse equivalents.

Abstract: A method of treating cancer in a subject in need thereof includes administering to the subject therapeutically effective amounts of a PP2A activator and a BER inhibitor, such a PARP inhibitor.

Abstract: A method of treating cancer in a subject in need thereof includes administering to the subject therapeutically effective amounts of a PP2A activator and a protein kinase inhibitor.

Abstract: Tricyclic chemical modulators of FOXO transcription factor proteins are disclosed. The compounds are useful to treat cancer, age-onset proteotoxicity, stress-induced depression, inflammation, and acne.

Abstract: The present invention relates to anti-cancer therapeutics. In certain aspects, cancers are treated with a combination of an anti-EGFR agent and an agent that increases the activity of the KLF6 tumor suppressor gene and/or an agent that increases activity of the FOXO1 tumor suppressor gene. In a preferred aspect, the anti-EGFR agent erlotinib a tricyclic agent compound, are used in combination to treat non-small cell lung cancer in a patient with primary or acquired drug resistance to erlotinib, and wherein the tricyclic agent is administered in an amount that does not lead to a substantial central nervous system effect. In additional aspects, the invention relates to compositions and kits useful for treating cancers, methods for screening for compounds that enhance the activity of anti-EGFR agent, and methods for determining whether a patient will respond to anti-EGFR therapy.

Abstract: The present invention relates to combination therapies for the treatment of EGFR-related diseases, particularly EGFR-related cancers. This invention also relates to a method of enhancing the efficacy of an EGFR family member antagonist and therapeutic methods for subjects who are refractory to treatment with an EGFR family member antagonist. The invention also relates to pharmaceutical compositions useful for treatment of EGFR-related diseases.

Abstract: Disclosed are methods of identifying and diagnosing certain types of cancers and pre-stages thereof in a patient by identifying alternatively spliced isoforms of wild type KLF6 (KLF6wt), in particular any one of the isoforms selected from the group consisting of: KLF6 splice variant-1 (KLF6SV1), KLF6 splice variant-2 (KLF6SV2), and KLF6 splice variant-3 (KLF6SV3). Also disclosed are methods for diagnosing cancer using the polypeptides and polynucleotides identified herein, as well as methods of treating certain types of cancers by inhibiting polynucleotides and polypeptides identified herein.
