  • Publication number: 20100112713
    Abstract: The present invention relates to methods and compositions for the detection of biomarkers associated with colorectal diseases and disorders. In preferred embodiments, said colorectal disease is colorectal cancer. In some embodiments, the invention relates to the detection of said biomarkers using non-invasive methods. In further embodiments, the invention relates to the isolation and evaluation of biomarkers residing in feces from a subject at risk for or exhibiting symptoms associated with a colorectal disease or disorder. In still further embodiments, said biomarkers include exfoliated colonocytes. In additional embodiments, mRNA transcripts isolated from said colonocytes and associated with said colorectal diseases and disorders are quantified.
