Figure 12. Quantitative real-time polymerase chain reaction (qRT-PCR). (A–D) ANP32B, FTCD, ADH4 and PON1 were differentially expressed in HCC cells and normal para-cancer tissues. The expression levels of these four genes were all downregulated in HCC, and the expression levels of ADH4 and PON1 were very low. (**P<0.01).
