Abstract: The present invention relates to diagnosing abnormal cell proliferation in biological samples and screening for drugs which inhibit, reduce or abolish cell growth, especially tumorigenic cell growth, by detecting a phosphovariant isoform of a guanine nucleotide exchange factor biomarker, such as the novel GEF-H1S.

Abstract: The present invention encompasses type-I IFN and IFN?-induced PD marker expression profiles, kits, and methods for identifying such IFN?-induced PD marker expression profiles. The type-I IFN and IFN?-induced PD marker expression profiles may also be used in, for example, methods of treating patients having a type-I IFN or IFN?-mediated disorder, methods of monitoring disease progression of patients receiving treatment with a therapeutic agent that binds to and modulates IFN? activity, identifying patients as candidates to receive a therapeutic that binds to and neutralizes IFN? activity, and in diagnosing or providing a prognosis to patients having IFN?-induced disorders.

Abstract: The present invention relates to the use of phosphorylated p21-activated protein kinases (PAK), especially PAK4, as biomarkers of tumorogenesis. The present invention contemplates the use of phosphospecific antibodies for detecting phosphorylated PAK from mammalian biopsies, as well as screening assays for identifying compounds that modulate PAK activity. Also contemplated is a method for determining a subset of a given population that is amenable to treatment with a compound that modulates PAK activity.

Abstract: Methods for identifying subjects having a cancer or pre-malignant condition that will benefit from anti-CD40 therapeutic agents that modulate CD40L-mediated CD40 signaling are provided. The methods comprise the use of biomarkers of cellular apoptosis, cell proliferation and survival, and CD40 signaling pathways to monitor ex vivo response to one or more anti-CD40 therapeutic agents of interest that modulate CD40 signaling on CD40-expressing neoplastic cells. The ex vivo prognostic assays can be used alone or in conjunction with other prognostic assays to identify candidate subjects who will benefit from treatment with anti-CD40 therapeutic agents. Methods of the invention also comprise the use of these biomarkers to monitor in vivo efficacy of treatment with an anti-CD40 therapeutic agent.

Abstract: The present invention provides anti-human ICOS antibodies with increased effector function. The invention further relates to pharmaceutical compositions, immunotherapeutic compositions, and methods using therapeutic antibodies that bind to the human ICOS antigen and that may mediate ADCC, CDC, and/or antibody-dependent phagocytosis (opsonisation) for the treatment and prevention of T cell-mediated diseases and disorders, such as, but not limited to, chronic infection, autoimmune disease or disorder, inflammatory disease or disorder, graft-versus-host disease (GVHD), transplant rejection, and T cell proliferative disorder.

Abstract: The invention relates to trifluoromethyl sulfonyl and trifluoromethyl sulfonamido compounds and the physiologically acceptable salts and the prodrugs thereof. These compounds are expected to modulate the activity of protein tyrosine enzymes which are related to cellular signal transduction, in particular, protein tyrosine phosphatase, and therefore are expected to be useful in the prevention and treatment of disorders associated with abnormal protein tyrosine enzyme related cellular signal transduction such as cancer, diabetes, immuno-modulation, neurologic degenerative diseases, osteoporosis and infectious diseases. The invention also relates to the use of compounds containing fluoromethyl sulfonyl groups as phosphate mimics. These mimics may be used to inhibit, regulate or modulate the activity of a phosphate binding protein in a cell.
