Disclosed are methods of treating colorectal cancer that involve administering a composition comprising an effective amount of miR-451a to cells in the colorectal cancer and further treating the colorectal cancer cells with ionizing radiation. Also disclosed are methods of predicting whether a colorectal cancer in a subject will respond to ionizing radiation. These methods involve measuring the RNA expression of miR-451a, miR-1322, miR-133-3p, miR-1, miR-205-5p, miR-4521, CAB39, EMSY, or MEX3C in the sample and measuring the RNA expression of the same marker in a control. |
