Fig. 1: The differential expression of circRNAs in HCC tissues.

The differential expression of circRNAs in three pairs of HCC and non-tumor liver tissues was analyzed by microarray. a The heat mapping of some differentially expressed circRNAs. b Quantitative RT-PCR analysis of relative expression levels of the indicated circRNAs in five pairs of specimens. c Quantitative RT-PCR analysis of relative levels of the indicated circRNAs in different types of cells. d Quantitative RT-PCR analysis of relative levels of has_circ_0005692 (circRNA-5692) in 92 pairs of HCC and non-tumor liver tissues. Data are a representative image or expressed as the mean or mean ± SEM of each group from three separate experiments. **P < 0.01. c cancer tissues, p para-non-tumor tissues.
