On the other hand, moderate and strong staining patterns for CD44, DPP4, and SLC7A11 were observed in the cytoplasm and cell membrane of tumor tissues (Figure 4B, 4D, 4F), while NCOA4 only exhibited weak positive staining on the cell membrane of tumor tissues (Figure 4G, 4H). The gene discussed is SLC7A11; the disease is neoplasm.
