We then assessed protein levels associated with the three mRNAs in HCC cells using the Human Protein Atlas, finding results similar to those for mRNA levels (Figure 7), with elevated IGF2R levels in HCC tissues relative to normal tissues (Figure 7A) and lower CFB and PON1 levels observed in HCC tissues relative to normal tissues (Figure 7B, 7C). This evidence concerns the gene PON1 and hepatocellular carcinoma.
