FoxO4 was expressed in the cytoplasm in liver tissues in the 4TLM and 67NR groups, and its expressions levels were higher in both metastatic 4TLM and non-metastatic 67NR liver tissue non-vascular immune cells (p ˂ 0.05) compared to tumor-free liver tissue, in which FoxO4 expression was not determined (Figure 3c). The gene discussed is FOXO4; the disease is neoplasm.
