Immunohistochemistry (IHC) staining on orthotopic tumor showed that EIF3H KD led to reduced levels of EIF3H, HAX1 and pERK1/2, and repressed cell proliferation (Ki67 staining), while HAX1 overexpression reversed these impacts caused by EIF3H KD (Fig. 5d). This evidence concerns the gene MKI67 and neoplasm.
