Although OCT3 (SLC22A3) mRNA expression was also downregulated (Figure 1D), the overall survival rate of HCC patients with low expression of SLC22A3 mRNA was not significantly different from that of patients with high SLC22A3 mRNA expression (p = 0.27; Figure 2B). The gene discussed is SLC22A3; the disease is hepatocellular carcinoma.
