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.

GEF-H1b: biomarkers, complexes, assays and therapeutic uses thereof

GEF-H1b: biomarkers, complexes assays and therapeutic uses thereof

The present invention relates to PTP05 polypeptides and PTP10 polypeptides, nucleic acids encoding such polypeptides, cells, tissues and animals containing such nucleic acids, antibodies to such polypeptides, assays utilizing such polypeptides, and methods relating to all of the foregoing. Methods for treatment, diagnosis, and screening are provided for PTP05 and/or PTP10 related diseases or conditions characterized by an abnormal interaction between a PTP05 polypeptide and a PTP05 binding partner and/or a PTP10 polypeptide and a PTP10 binding partner.

Diagnosis and treatment of PTP related disorders

The present invention relates to PTP04 polypeptides, nucleic acids encoding such polypeptides, cells, tissues and animal containing such nucleic acids, antibodies to such polypeptides, assays utilizing such polypeptides, and methods relating to all of the foregoing. Methods for treatment, diagnosis, and screening are provided for PTP04 related diseases or conditions characterized by an abnormal interaction between a PTP04 binding partner.

Diagnosis and treatment of PTP04 related disorders

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.

Phosphate mimics and methods of treatment using phosphatase inhibitors

The present invention relates to PTP04 polypetides, nucleic acids encoding such polypeptides, cells, tissues and animals containing such nucleic acids, antibodies to such polypeptides, assays utilizing such polypeptides, and methods relating to all of the foregoing. Methods for treatment, diagnosis, and screening are provided for PTP04 related diseases or conditions characterized by an abnormal interaction beteeen a PTP04 polypeptide and a PTP04 binding partner.
