Studies have confirmed that AC008760.1, AC006329.1, AL590483.1, CASC9 and AC010973.2 (25) can be potential biomarkers for colorectal cancer (25–28), while there are few studies about AL139384.1, LINC01876, AP001469.3, CAPN10-DT, ZKSCAN2-DT, AP006621.4, and AL161729.4 in solid tumors. Here, CASC9 is linked to colorectal cancer.
