Selection of Suitable Reference Genes for qPCR Gene Expression Analysis of HepG2 and L02 in Four Different Liver Cell Injured Models

Figure 2

Expression stability of the reference genes in HepG2 evaluated by geNorm values represents the average expression stability. From left to right, the value of decreased in turn, indicating the stability gradually increased. Smaller value means higher stability. The control group, ethanol, hydrogen peroxide, acetaminophen, and carbon tetrachloride were abbreviated to WT, EtOH, H2O2, APAP, and CCl4, respectively.
