Abstract

The current disclosure provides for specific peptides, and derived ionization characteristics of the peptides, from the tyrosine-protein kinase receptor UFO protein (AXL) that are particularly advantageous for quantifying the AXL protein directly in biological samples that have been fixed in formalin by the method of Selected Reaction Monitoring (SRM) mass spectrometry, or what can also be termed as Multiple Reaction Monitoring (MRM) mass spectrometry. Such biological samples are chemically preserved and fixed wherein said biological sample is selected from tissues and cells treated with formaldehyde containing agents/fixatives including formalin-fixed tissue/cells, formalin-fixed/paraffin embedded (FFPE) tissue/cells, FFPE tissue blocks and cells from those blocks, and tissue culture cells that have been formalin fixed and or paraffin embedded. A protein sample is prepared from said biological sample using the Liquid Tissue reagents and protocol and the AXL protein is quantitated in the Liquid Tissue sample by the method of SRM/MRM mass spectrometry by quantitating in the protein sample at least one or more of the peptides described. These peptides can be quantitated if they reside in a modified or an unmodified form. An example of a modified form of an AXL peptide is phosphorylation of a tyrosine, threonine, serine, and/or other amino acid residues within the peptide sequence.

Abstract

Improved methods for treating lung cancer are provided. Tumor samples from patients are analyzed (i) by DNA sequencing to detect the presence of HER2 mutations and (ii) by mass spectrometric proteomic analysis to determine whether HER2 protein is expressed in the tumor cells. Patients respond to therapy with trastuzumab emtansine (T- DM1) or an equivalent antibody-drug conjugate when unique HER2 protein fragments are detected in the patient's tumor cells that harbor HER2 mutations. Conversely, patients do not respond to T-DM1 therapy when the tumor cells contain HER2 mutations but the unique protein fragments are not detected. Detection of HER3 in the tumor cells is a positive predictor of response to treatment.

Abstract

Objective quantitation of the c-Src protein directly in cancer patient tissue can aid in determining the aggressiveness of an individual patient's tumor as well as help make more informed decisions about choice of therapy. However, the c-Src protein is currently analyzed directly in formalin fixed patient tissue only by immunohistochemistry methodology which is at best subjectively semi-quantitative. This invention describes an objective quantitative assay for the c-Src protein using mass spectrometry as the analytical methodology. Specific peptides, experimentally discovered characteristics about the peptides, and experimentally established assay conditions based on those peptide characteristics are provided for use in a mass spectrometry-based Selected Reaction Monitoring (SRM) assay in order to measure relative or absolute quantitative levels of c-Src directly in a protein preparation obtained from a formalin fixed cancer patient tissue sample.

Abstract

This patent application discloses and describes proteins found to be differentially expressed between primary tumor breast cancer cells that did not give rise to recurrent breast cancer disease after initial diagnosis and primary breast cancer cells that did give rise to recurrent breast cancer disease after initial diagnosis. These proteins can be used either individually or in specific combinations in diagnostic and prognostic protein assays on various biological samples from breast cancer patients to indicate the likelihood that a breast cancer patient's cancer will recur after initial diagnosis and treatment. Determination of differential expression of these proteins can also be useful for indicating additional therapies to combat the likelihood of recurrent breast cancer. The full length intact proteins can be assayed or peptides derived from these proteins can be assayed as reporters for these proteins. These proteins can also be identified as "companion diagnostic" proteins, wherein the differentially expressed proteins that arc used as diagnostic and prognostic indicators can also be used as targets for therapeutic intervention of breast cancer. Also disclosed and described herein are isotope labeled versions of peptides from the proteins.

Abstract

The current disclosure provides for specific peptides, and derived ionization characteristics of the peptides, from the Insulin-Like Growth Factor 1 Receptor (IGF- I R) protein that are particularly advantageous for quantifying the IGF-IR protein directly in biological samples that have been fixed in formalin by the method of Selected Reaction Monitoring (SRM) mass spectrometry, or what can also be termed as Multiple Reaction Monitoring (MRM) mass spectrometry. Such biological samples are chemically preserved and fixed wherein said biological sample is selected from tissues and cells treated with formaldehyde containing agents/fixatives including formalin-fixed tissue/cells, formalin- fixed/paraffin embedded (FFPE) tissue/cells, FFPE tissue blocks and cells from those blocks, and tissue culture cells that have been formalin fixed and or paraffin embedded. A protein sample is prepared from said biological sample using the Liquid Tissue™ reagents and protocol and the IGF- I R protein is quantitated in the Liquid Tissue™ sample by the method of SRM/MRM mass spectrometry by quantitating in the protein sample at least one or more of the peptides described. These peptides can be quantitated if they reside in a modified or an unmodified form. An example of a modified form of an IGF-I R peptide is phosphorylation of a tyrosine, threonine, serine, and/or other amino acid residues within the peptide sequence.

Abstract

This patent application discloses and describes a list of proteins that are found to be differentially expressed between normal endometrial epithelial cells and early stage cancerous endometrial epithelial cells. These proteins can be used either individually or in specific combinations in diagnostic and prognostic protein assays on various biological samples from endometrial cancer patients, or individuals suspected on having endometrial cancer. In addition, these proteins are also differentially expressed between normal endometrial epithelial cells and epithelial cells of other types of endometrial disease, and thus such diseases can be diagnosed using assays based on these proteins. The full length intact proteins can be assayed or peptides derived from these proteins can be assayed as reporters for these proteins. These proteins can also be identified as "companion diagnostic" proteins, wherein they are not only differentially expressed for use as diagnostic and prognostic indicators of endometrial cancer and other endometrial diseases, but the same proteins are also targets for therapeutic intervention of endometrial cancer and other endometrial diseases.
