摘要:
Provided herein are methods of detecting cancer, diagnosing a subject with cancer, treating a subject with cancer, and reducing the risk of or preventing cancer in a subject. The methods are based in part on the discovery of dysregulated protein citrullination by protein arginine deaminase enzymes in cancer. Also provided are citrullinated peptides and kits that are expressed at a higher level in cancer cells than in corresponding normal cells. Kits and systems relating to these methods are also provided.
摘要:
The present invention relates to the field of biomarkers. More specifically, the present invention relates to biomarkers useful in diagnosing brain injury or neurodegeneration. In one embodiment, a method for diagnosing brain injury in a patient comprises the steps of (a) obtaining a sample from the patient; (b) determining the ratio of citrullinated to unmodified arginine residues at one or more arginine residues of one or more brain injury biomarker proteins; and (c) correlating the ratio to a patient having brain injury or to a patient not having brain injury, thereby providing the diagnosis.

The present invention provides citrullinated 14-3-3η peptides and antibodies thereto and methods of using same to evaluate arthritic conditions such as rheumatoid arthritis.
摘要:
Novel phenyl-glyoxal based anti-citrulline probes and methods of synthesis are provided. Methods of use, such as, the development of methods for monitoring substrate citrullination over time; for identifying citrullinated proteins from cells are described.
摘要:
Aspects of the application relate to methods and systems for obtaining information regarding multiple amino acids in a polypeptide based on binding interactions between the polypeptide and one or more amino acid recognizers. Kinetic signature information may be obtained from a series of signal pulses indicative of a series of binding events between one or more amino acid recognizers and an amino acid of a polypeptide (e.g., a terminal amino acid, an internal amino acid). The kinetic signature information (e.g., pulse duration, interpulse duration, recognition segment (RS) duration, intersegment duration) may be used to determine one or more chemical characteristics (e.g., identity, modification) of multiple amino acids of the polypeptide.
摘要:
Anti-tumour immune responses to modified self-epitopes. The present invention relates to the use of tumour-associated epitopes in medicine and in particular in the treatment of cancer. The epitopes stimulate an immune reaction against the tumour and have a modification selected from deimination of arginine to citrulline, nitration of tyrosine, oxidation of tryptophan and deamination of glutamine or asparagine. The invention also relates to nucleic acids comprising sequences that encode such epitopes for use in the treatment of cancer.

摘要:
Methods of diagnosing sepsis, severe sepsis, or septic shock and predicting prognosis in subjects with septic shock, based on levels of citrullinated histone H3 (Cit H3) in the subject, e.g., in a sample comprising serum (e.g., whole blood, serum, or plasma), cerebrospinal fluid, urine, saliva, or peritoneal fluid from the subject.
