SRGN and neoplasm: Figure 2 provides a more in-depth analysis of SRGN expression across different macrophage subsets in LIHC. GEPIA analysis revealed that in LIHC tumor tissues, SRGN expression was highest in M2 macrophages, followed by M0 and M1 macrophages, when compared to liver tissues and LIHC-adjacent normal tissues (Figures 2A, B).
