We also verified the downregulated expression level of OIT3 in TCGA HCC samples via the GEPIA database (Figure 1C) and the UALCAN database (Figure 1D), finding that compared with early HCC, advanced tumors had lower expression of OIT3 (Figure 1E), indicating that OIT3 had a significant clinical relevance. Here, OIT3 is linked to hepatocellular carcinoma.
