COMPOSITION FOR TREATING AND/OR DIAGNOSING COLORECTAL CANCER, AND USE THEREFOR

摘要

The present invention treats colorectal cancer by using a composition containing an miR-31 inhibitor. The present invention diagnoses on the basis of the amount of miR-31 expression in a biological sample derived from a colorectal cancer patient. The present invention prepares a colorectal-cancer cell containing miR-31 or an miR-31 mimic, and screens a drug for treating colorectal cancer by using this colorectal-cancer cell. As a result, the present invention provides a technique for treating and/or diagnosing colorectal cancer having KRAS or BRAF mutations.
