Furthermore, the results of immunohistochemistry suggested that eIF5A was significantly reduced (Figures 6(f) and 6)(g), and the ferroptosis marker proteins (FANCD2, SLC7A11, and HSPb1) were significantly downregulated in the tumor tissues of sh-eIF5A group mice (Figures 6(f) and 6)(h). The gene discussed is SLC7A11; the disease is neoplasm.
