Expression of miR-188 in hepatocellular carcinoma (HCC) cell lines and noncancerous cells. A Relative expression of miR-188-5p in HCC tumor and peri-tumor. B qPCR was performed to detect miR-188 levels in noncancerous hepatic cells (QSG7701 and HL7702) and HCC cell lines (non-invasive Hep3B and HepG2, low-metastatic Huh7, Bel7402, HLE, HLF, SMMC7721, and metastatic HCC97H and HCC-LM3 cells). C Kaplan–Meier analysis of disease-free survival of 94 HCC patients according to miR-188-5p expression levels in HCC tissues. D Kaplan–Meier analysis of overall survival of 94 HCC patients according to miR-188-5p expression levels in HCC tissues.* P < 0.05, ** P < 0.01
