Figure 1: HULC is up-regulated in HCC tissues. Receiver-operating characteristic (ROC) curve (a) and box plots (b) of HULC RNA expression in HCC tissues and healthy control liver tissues. (a) The area under the ROC curve was 0.86 in distinguishing hepatocellular carcinoma versus healthy control. (b) HULC expression was examined in 20 healthy control liver tissues and 30 HCC tissues by qRT-PCR. Data were analyzed using the method. The upper and lower limits of the boxes and the lines inside the boxes indicate the 75th and 25th percentiles and the median, respectively. The upper and lower horizontal bars denote the 90th and 10th percentiles, respectively.
