High lncRNA-TP73-AS1 expression in HCC was correlated with poorer prognosis a TP73-AS1 expression in a large panel of 84 paired cases of HCC tissues and adjacent normal tissues was determined by using real-time PCR. b Expression of TP73-AS1 in 84 pairs of HCC tissues and their corresponding adjacent non-tumorous tissues (ANTs) in a training cohort. Expression level of TP73-AS1 was determined by real-time PCR and normalized to U6. Fold change was analyzed using the formula 2-(ΔΔCT [HCC/ ANT]). c Kaplan-Meier overall survival curves for 84 patients with HCC classified according to relative TP73-AS1 expression level. d TP73-AS1 expression in five human HCC cell lines, HCCLM3, MHCC97L, SMMC7722, Hep3B and HepG2 was upregulated compared to normal cell line, THLE-3. *P < 0.05, **P < 0.01
