The method of the present invention determines the overall expression of MSH3 in cells suspected of being colorectal cancer cells from the patient and predicting the efficacy of therapy with a genotoxic anti-neoplastic agent for treating the patient, wherein a decrease in the overall expression of MSH3 in the patient cells when compared to the expression of MSH3 in normal colorectal cells indicates a predisposition to responsiveness to genotoxic anti-neoplastic agent therapy, wherein the therapy comprises administering an effective amount of the genotoxic anti-neoplastic agent therapy to patients. | 08-16-2012 |
20120237929 | LONG INTERSPERSED NUCLEAR ELEMENTS (LINE-1) AND ALU HYPOMETHYLATION AS BIOMARKERS FOR COLORECTAL CANCER METASTASIS - A method for determining a colorectal cancer metastasis in a human subject suffering from a primary colorectal cancer (CRC) is described herein. The method of the present invention comprises the steps of: i) identifying the human subject suffering from the primary CRC, ii) obtaining one or more biological samples from the human subject, iii) detecting a methylation level of Alu, LINE-1, or both in the one or more biological samples, and iv) increasing the level of the colorectal metastatic stage in the human subject when the methylation level of Alu, LINE-1 is lower compared to a corresponding control methylation level of Alu, LINE-1. | 09-20-2012 |
20120238463 | LINE-1 Hypomethylation as a Biomarker for Early-Onset Colorectal Cancer - A method for detecting an early-onset of colorectal cancer in a human subject is disclosed herein. The method comprises the steps of: (i) identifying the human subject suspected of suffering from a colorectal cancer, (ii) obtaining one or more biological samples from the human subject; (iii) determining a LINE-1 methylation level for the one or more biological samples; and (iv) comparing the LINE-1 methylation level to a LINE-1 methylation control level, wherein a higher degree of the LINE-1 methylation level is indicative of an early-onset colorectal cancer. | 09-20-2012 |
20120264131 | CHANGES IN THE EXPRESSION OF miR-200c/141 CLUSTER OF microRNAs AS BIOMARKERS FOR EPITHELIAL-TO-MESENCHYMAL TRANSITION IN HUMAN COLORECTAL CANCER METASTASIS - The present invention includes methods, kits and biomarkers for detecting and determining the development of colorectal cancer (CRC) metastasis based on changes in the expression pattern of one or more microRNAs (miR) or miR clusters that include the miR-200/141 family. | 10-18-2012 |
20120295267 | Detecting DNA Mismatch Repair-Deficient Colorectal Cancers - Use of a CAT25 mononucleotide marker in a novel tetraplex PCR for the detection of MSH6-defective colorectal cancers (CRCs) is described herein. The tetraplex PCR of the present invention offers a facile, robust, less expensive (compared to the original pentaplex assay), highly sensitive, and specific assay for the identification of microsatellite instability (MSI) in CRCs. | 11-22-2012 |
20130164279 | Micro RNA-148A as a Biomarker for Advanced Colorectal Cancer - The present invention includes methods of detection, diagnosis, prognosis, and treatment of a patient suspected of having a colorectal cancer comprising obtaining one or more samples of the patient, determining a level of expression of miR-148a or the level of methylation of a miR-148a promoter, and predicting a response to a cytotoxic chemotherapy cancer treatment. | 06-27-2013 |
20130288247 | NOVEL DNA HYPERMETHYLATION DIAGNOSTIC BIOMARKERS FOR COLORECTAL CANCER - The present invention relates to the field of cancer. More specifically, the present invention relates to the use of biomarkers to detect colorectal cancer. In one aspect, the present invention provides methods for qualifying colorectal cancer status including, but not limited to, diagnosis, prognosis, and risk stratification, in patients. In one embodiment, a method for diagnosing colorectal cancer (CRC) in a patient comprises the steps of (a) collecting a sample from the patient; (b) measuring the methylation levels of one or more biomarkers in the sample collected from the patient; and (c) comparing the methylation levels of the one or more biomarkers with predefined methylation levels of the same biomarkers that correlate to a patient having CRC and predefined methylation levels of the same biomarkers that correlate to a patient not having CRC, wherein a correlation to one of the predefined methylation levels provides the diagnosis. | 10-31-2013 |
20140322354 | TISSUE & BLOOD-BASED MIRNA BIOMARKERS FOR THE DIAGNOSIS, PROGNOSIS AND METASTASIS-PREDICTIVE POTENTIAL IN COLORECTAL CANCER - Methods and compositions for the diagnosis, prognosis and classification of cancer, especially colorectal cancer, are provided. For example, in certain aspects methods for cancer prognosis using expression or methylation analysis of selected biomarkers are described. Particular aspects of the present invention may include methods and biomarkers for diagnosing or detecting colorectal cancer or metastasis in a subject by measuring a level of expression of biomarker miRNA such as miR-885-5p in the sample from the subject and evaluating the risk of developing cancer or metastasis in the subject. | 10-30-2014 |
