  • Publication number: 20150191796
    Abstract: 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.

  • Patent number: 8669058
    Abstract: 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.

  • Publication number: 20140057258
    Abstract: 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.
