Abstract: Altered protein products resulting from somatic mutations are directly identified and quantified by mass spectrometry. The peptides expressed from normal and mutant alleles are detected by Selected Reaction Monitoring (SRM) of their productions using a triple quadrupole mass spectrometer. As a prototypical example of this approach, we quantify the number and fraction of mutant Ras protein present in cancer cell lines. There were an average of 1.3 million molecules of Ras protein per cell and the ratio of mutant to normal Ras proteins ranged from 0.49 to 5.6. Similarly, we detected and quantified mutant Ras proteins in clinical specimens such as colorectal and pancreatic tumor tissues as well as in pre-malignant pancreatic cyst fluids. These methods are useful for diagnostic applications.

Abstract: Methods are disclosed herein for specifically inducing proliferation of CD4+ T cells. The methods are of use in treating immunodeficiencies, such as an immunodeficiency produced by infection with an immunodeficiency virus, such as infection with a human immunodeficiency virus (HIV). The methods include contacting isolated mammalian CD4+ T cells with an effective amount of a thymic stromal derived lymphopoietin (TSLP) polypeptide or a therapeutically effective amount of nucleic acid encoding the TSLP polypeptide, thereby inducing proliferation of the T cells. Methods are also disclosed for treating an IgE mediated disorder, such as asthma. The methods include administering to a subject a therapeutically effective amount of a TSLP antagonist. Transgenic mice are also disclosed herein.

Abstract: The present invention provides Thymic Stromal Lymphopoietin Receptor (TSLPR) polypeptides and nucleic acid molecules encoding the same. The invention also provides selective binding agents, vectors, host cells, and methods for producing TSLPR polypeptides. The invention further provides pharmaceutical compositions and methods for the diagnosis, treatment, amelioration, and/or prevention of diseases, disorders, and conditions associated with TSLPR polypeptides.

Abstract: The invention relates to the identification and quantification of proteins differentially expressed during adipogenesis. More specifically, the invention relates to methods for identifying and/or quantitating proteins differentially expressed in one or more specific stage(s) of adipocyte differentiation, using mass spectrometry. The invention also provides those differentially expressed genes as marker genes of adipogenesis. The invention further provides treatment methods for patients suffering from conditions associated with hyper- or hypo-adipogenesis.
