Zheng et al identified more than 27 000 circRNA candidates from the sequencing data of seven human cancers, including breast cancer, gastric cancer, kidney clear cell carcinoma, prostate adenocarcinoma, bladder cancer, colorectal cancer and hepatocellular carcinoma (HCC).32 For the role of CDR1as in cancer, CDR1as was up‐regulated in HCC tissues and the knockdown of CDR1as suppressed the progression of HCC.33 Here, LINC00632 is linked to cancer.
