Several lncRNAs, such as lncRNA RoR, lncRNA BC200, lncRNA AK023948 (breast carcinoma), lncRNA UCA (Urothelial cancer associated 1) (bladder), lncRNA 01116 (prostrate), lncRNA CCAT2 (colon cancer-associated transcript 2), lncRNA 21A (colorectal carcinoma), and lncRNA PANDAR (gastric cancer), have been successfully edited by CRISPR-Cas9, and functional validation experiments have proved that these lncRNAs are oncogenic in nature [118]. Here, CCAT2 is linked to colorectal carcinoma.
