DRD2 Biomarker Composition for Diagnosing Colorectal Cancer Specifically Binding to Arginine-methylated Dopamine Receptor D2

摘要

The present invention relates to a biomarker composition for diagnosing colorectal cancer and a diagnostic kit for diagnosing colorectal cancer using an expression level of DRD2 (Dopamine Receptor D2) methylated with arginine as an index, and a method for providing information for colorectal cancer diagnosis. By using an antibody that specifically recognizes the diagnostic biomarker arginine methylated DRD2 protein, the expression level of DRD2 methylated arginine in the blood of a suspected cancer patient is measured, so blood can be analyzed easily without biopsy from the patient. , When the expression of DRD2 in which arginine is methylated is lower than that in normal people, it can be diagnosed as colon cancer.
