Relative expression of circPVT1 in HCC tissues and HCC cell lines and its prognosis potential in HCC patients. (A) CircPVT1 expression was detected in 70 pairs of HCC tissues and adjacent non-tumor tissues by qRT-PCR, Wilcoxon signed-rank test. (B) Relative expression of circPVT1 in HCC cell lines and normal liver cells was measured by qRT-PCR. (C) The relationship between relative expression of circPVT1 and HCC patients' overall survival was analyzed by log-rank test and Kaplan–Meier method. *P<0.05, **P<0.01, ***P<0.001. Mean±s.e., n=3 in B.
