Provided herein are methods for identifying and treating subjects having conditions involving reduced HSF1 activity (e.g., diminished HSF1 activity, diminished HSF1 protein levels, increased HSF1 Ser303 phosphorylation, increased HSF1 Ser307 phosphorylation) or conditions that benefit from increasing HSF1 abundance or activity beyond physiological levels.

The present invention refers to p53 sequence and post translational modifications (PTMs) and to their use as biomarkers in the diagnosis of neurodegenerative disease and cognitive decline and/or in the prognosis of Alzheimer's disease at different stages and/or of neurodegenerative disease in a biological sample. The invention also provides for a 1) diagnostic method based on a highly accurate mass spectrometry analysis for the diagnosis of neurodegenerative disease, including Mild Cognitive Impairment (MCI), Alzheimer's disease (AD), fronto-temporal dementia (FTD), Lewi's Body (LB), and vascular dementia (VD) in a subject, by evaluating the PTMs to the said p53 linear sequence protein and possible cut of its full sequence specifically in human plasma of patients; and 2) prognosis of AD in CU and MCI patients.

Methods for assessing the quality of a tissue sample. In some aspects, methods are provided for determine the time that a biological sample has been exposed to cold ischemia condition by measuring the expression level of an mRNA and/or a phosphoprotein.

The present invention relates to the diagnosis and treatment of cancer, and specifically to a method of diagnosing the presence, status or metastasis of cancer by detecting plasma Hsp90α having the amino acid sequence of SEQ ID NO:1 as a tumor marker. In addition, the present invention also relates to a method for the treatment of cancer and metastasis.

A phosphoprotein extraction method and a mass spectrometric method using a microbore hollow fiber enzymatic reactor (mHFER) based antigen-antibody reaction and, specifically, to an extraction method and a mass spectrometric method, wherein phosphoproteins or phosphopeptides present in the body are extracted using phosphoserine-, phosphothreonine-, and phosphotyrosine-antibodies, and measured by a mass spectrometer, and thus biomarker phosphoproteins for diagnosis of diseases are found, contributing to early diagnosis of diseases. The mass spectrometric method using the antigen-antibody reaction based extraction method can: minimize temporal and economic burdens resulting from a low extraction rate and a complicated sample pre-treatment; increase the extraction efficiency by using a considerable number of phosphopeptides (or phosphoproteins) and antibodies with strong affinity; and allow the extraction of low-concentration phosphopeptides or phosphoproteins, and thus is expected to have high applicability in discovering disease diagnosis protein markers and identifying and studying mechanisms thereof.

A set of phosphorylated peptides are presented by HLA A*0101, A*0201, A*0301, B*4402, B*2705, B*1402, and el B*0702 on the surface of melanoma cells. They have the potential to (a) stimulate an immune response to the cancer, (b) to function as immunotherapeutics in adoptive T-cell therapy or as a vaccine, (c) to facilitate antibody recognition of the tumor boundaries in surgical pathology samples, and (d) act as biomarkers for early detection of the disease. Phosphorylated peptides are also presented for other cancers.

One aspect of the technology relates to methods, assays and kits to identify ischemia and ischemic injury, including kidney injury, and are useful in determining efficacy of cancer treatments. In particular, differential phosphorylation of the nucleophosmin (NPM) polypeptide is an early marker of ischemic injuries such as kidney injury, AKI and ischemic renal cell injury. Another aspect of the technology relates to compositions and methods for the treatment of ischemia and kidney injury, including NPM inhibitory agents, including, but not limited to NPM inhibitory peptides for the treatment of ischemia and kidney injury.

Therapeutic treatments of a tumor expressing pT346 PDK1, including glioma expressing pT346 PDK1, are disclosed.

This document provides methods and materials involved in identifying mammals (e.g., humans) having cancer cells with an elevated level of phosphorylated Ub polypeptides (e.g., an elevated level of Y59 phosphorylated Ub polypeptides). For example, methods and materials for detecting the presence of cancer cells having an elevated level of Y59 phosphorylated Ub polypeptides are provided.

The present application provides stable peptide-based Akt capture agents and methods of use as detection and diagnosis agents and in the treatment of diseases and disorders. The application further provides methods of manufacturing Akt capture agents using iterative on-bead in situ click chemistry.
