The invention relates to the identification and selection of novel biomarkers and the identification and selection of novel biomarker combinations which are differentially expressed in individuals with mild osteoarthritis as compared with individuals without osteoarthritis. Polynucleotides and proteins which specifically and/or selectively hybridize to the products of the biomarkers of the invention are also encompassed within the scope of the invention as are kits containing said polynucleotides and proteins for use in diagnosing mild osteoarthritis. Further encompassed by the invention is the use of the polynucleotides and proteins which specifically and/or selectively hybridize to the product of the biomarkers of the invention to monitor disease regression in an individual and to monitor the efficacy of therapeutic regimens. The invention also provides for methods of using the products of the biomarkers of the invention in the identification of novel therapeutic targets for osteoarthritis.


The present invention relates generally to the identification of biomarkers of conditions including disease and non disease conditions as well as identifying compositions of biomarkers. The invention further provides a method of diagnosing disease, monitoring disease progression, and differentially diagnosing disease. The invention further provides for kits useful in diagnosing, monitoring disease progression and differentially diagnosing disease.


A method of determining a probability that a human test subject has colorectal cancer as opposed to not having colorectal cancer is disclosed. The method comprises, for each gene of a set of one or more genes selected from the group consisting of ANXA3, CLEC4D, IL2RB, LMNB1, PRRG4, TNFAIP6 and VNN1: determining a level of RNA encoded by the gene in blood of the test subject, thereby generating test data; providing positive control data representing levels of RNA encoded by the gene in blood of human control subjects having colorectal cancer, and providing negative control data representing levels of RNA encoded by the gene in blood of human control subjects not having colorectal cancer; and determining a probability that the test data corresponds to the positive control data and not to the negative control data, where the probability that the test data corresponds to the positive control data and not to the negative control data represents the probability that the test subject has colorectal cancer as opposed to not having colorectal cancer.


In one aspect the invention is a method of testing for one or more colorectal pathologies or one or more subtypes of colorectal pathology (in one embodiment colorectal cancer) in a test individual by providing data corresponding to a level of products of selected biomarkers and applying the data to a formula to provide an indication of whether the test individual has one or more colorectal pathologies or one or more subtypes of colorectal pathology. In some aspects the method is computer based and a computer applies the data to the formula. In other aspects a computer system is configured with instructions that cause the processor to provide a user with the indication of whether the test individual has colorectal pathology. Also encompassed are kits for measuring data corresponding to the products of selected biomarkers which in some embodiments include a computer readable medium. Also encompassed are kits and methods of monitoring therapeutic efficacy of treatments for one or more colorectal pathologies.

The invention relates to the identification and selection of novel biomarkers and the identification and selection of novel biomarker combinations which are differentially expressed in osteoarthritis and/or in a particular stage of osteoarthritis, as well as a means of selecting the novel biomarker combinations. The measurement of expression of the products of the biomarkers and combinations of biomarkers demonstrates particular advantage in one or more of the following: (a) diagnosing individuals as having arthritis, (b) differentiating between two stages of osteoarthritis (OA) and (c) diagnosing individuals as having a particular stage of OA. Polynucleotides and proteins which specifically and/or selectively hybridize to the products of the biomarkers are within the scope of the invention as are kits containing said polynucleotides and proteins and the use of said polynucleotides and proteins. The biomarker products can be used to identify therapeutic targets for osteoarthritis, and compounds that bind and/or modulate the gene activity.


The present invention is directed to detection and measurement of gene transcripts in blood. Specifically provided is a RT-PCR analysis performed on a drop of blood for detecting, diagnosing and monitoring diseases using tissue-specific primers. The present invention also describes methods by which delineation of the sequence and/or quantitation of the expression levels of disease-associated genes allows for an immediate and accurate diagnostic/prognostic test for disease or to assess the effect of a particular treatment regimen.

The application provides a method of determining a severity of heart failure in a human test subject, by determining a level of RNA encoded by one or more heart failure marker genes in blood of the test subject compared to controls. The application also provides a method of determining survival outcome and allows the ranking of test subjects based on the level of RNA encoded by one or more survival associated genes.


A method is provided in various embodiments for determining a profile data set for a subject with colorectal cancer or conditions related to colorectal cancer based on a sample from the subject, wherein the sample provides a source of RNAs. The method includes using amplification for measuring the amount of RNA corresponding to at least 1 constituent from Tables 1-5. The profile data set comprises the measure of each constituent, and amplification is performed under measurement conditions that are substantially repeatable.
