Through the Human Protein Atlas (HPA) database, we also supplied the immunohistochemical images of the remaining model-constructed molecules in the HPA database, which indicated that there was a higher expression of GEMIN2, CDKN2A, and DLAT in HCC than in normal tissues (Supplementary Figure S1E), but the immunohistochemical data of KLF9 were not obtained. The gene discussed is GEMIN2; the disease is hepatocellular carcinoma.
