Abstract:
Human TTBK genes are identified as modulators of the beta catenin pathway, and thus are therapeutic targets for disorders associated with defective beta catenin function. Methods for identifying modulators of beta catenin, comprising screening for agents that modulate the activity of TTBK are provided.

Abstract:
The invention relates to methods for modulating cell death and cell survival and for modulating the sensitivity of cells towards agents that modulate cell death or cell survival. The invention also relates to the identification of kinases and phosphatases that promote cell survival or cell death. The invention further relates to methods for screening compounds that modulate the activity, expression and/or protein-protein interactions of cell survival or cell death-promoting kinases and phosphatases. Accordingly, kinases and/or phosphatases that modulate cell proliferation and death may serve as therapeutic targets for the development of new cancer treatments.
Abstract:
The present invention relates a method for screening for a PARP activator. The screening method comprises the step of assessing the PARP-activating effect of a test compound, using cells, cell lysate, or purified PARP. The present invention also provides a method for the treatment of cancers. The treatment method comprises administering to the subject a therapeutically effective amount of a PARP activator.
Abstract:
The present invention provides methods and systems for performing in vivo flow cytometry. In one embodiments, selected circulating cells of interest of a subject are labeled with fluorescent probe molecules. The labeled cells are irradiated in-vivo so as to excite the fluorescent probes, and the radiation emitted by the excited probes is detected, preferably confocally. The detected radiation is then analyzed to derive desired information, such as relative cell count, of the cells of interest. In some embodiments, the circulating cells comprise apoptotic cells whose detection can allow, e.g., non-invasive monitoring of the efficacy of a cancer treatment, such as an anti-tumor or an anti-angiogenic therapy.
Abstract:
The present invention provides complexes containing an ARTS protein and an IAP protein, compounds that disrupt same, and use of the compounds in treating neuro-degenerative disease, ischemic injury, myelodysplasia, atherosclerosis, various auto-immune diseases, cytopenia, pancreatitis, and periodonitis, and in decreasing susceptibility of a cell to apoptosis. The present invention also provides methods for identifying biologically active regions of ARTS protein, and use of mimetic compounds of same in treating apoptosis-related disorders, cancer, and other neoplastic diseases and disorders.
Abstract:
Disclosed are a composition for inducing apoptosis comprising a substance blocking procaspase-2 phosphorylation and TNF-related apoptosis-inducing ligand (TRAIL) and a method of inducing apoptosis using the composition. Also disclosed is a method of detecting a substance regulating phosphorylation of procaspase-2, comprising (a) contacting procaspase-2 with a candidate substance regulating phosphorylation of procaspase-2 and (b) measuring phosphorylation of procaspase-2. Further disclosed is a procaspase-2 variant protein which has at least one substitution of a nonpolar amino acid for the 140th serine residue and 0 to 3 serine residues at positions 63, 65 and 147.
Abstract:
Phenotypes and the cells that exhibit those phenotypes are described. The phenotype may be established as a "snapshot" of the cells at a particular time or it may be established as a variation in features over time, or as some combination of these "static" and "dynamic" characterizations. The phenotype may be characterized by at least the following features: (a) chromosomes that approach metaphase but fail to separate and maintain alignment compared to a control cell or cell population; (b) a bipolar spindle that is at least about 10% longer than a corresponding metaphase mitotic spindle from the control cell or cell population; and (c) during interphase the cell or population of cells exhibits a phenotype that is substantially similar to that of the interphase cells of the control cell or cell population.
Abstract:
Disclosed herein are compounds that inhibit Hsp90 interactions with IAP proteins, such as Survivin, XIAP, cIAP1, or cIAP2, and methods for identifying and using such compounds.
