Most studies have reported that lncRNA UCA1 is prone to regulate miRNA expression, but Zhao et al. revealed that miR-124, a tumor suppressor mRNA, reduced rho-associated protein kinase 1 (ROCK1) to suppress lncRNA UCA1 expression, leading to the inhibition of HCC cell proliferation, migration, and invasion [57]. Here, UCA1 is linked to hepatocellular carcinoma.
