This implies that these RNAs play diverse functions in different pathological or physiological conditions.43, 44, 45 For instance, the oncogene CDR1as is dysregulated in many tumors such as HCC.46 Previously, it was found that CDR1as was highly expressed in HCC samples and it was associated with the progression of HCC and hepatic microvascular invasion (MVI).47 This showed that CDR1as may cause MVI in HCC patients. This evidence concerns the gene LINC00632 and hepatocellular carcinoma.
