Figure Lengend Snippet: Establishment of an Inducible IRF1 expression nude mouse subcutaneous xenograft and lung metastasis model. A : In vivo experiments show that the tumor volume of the IRF1 overexpression group in nude mouse subcutaneous xenografts is significantly smaller than that of the control group (Mean ± SEM). B : Gross anatomy of subcutaneous xenograft tumors in nude mice. C : HE staining of subcutaneous xenograft tumors (tumor tissues from mouse #1 and #2). D : Immunohistochemistry (IHC) analysis of IRF1 expression in subcutaneous xenograft tumors, showing significant IRF1 overexpression in the Dox (+) group. E : Bioluminescence imaging of nude mice injected via the tail vein with BGC-IRF1-LUC cells at 0, 2, 3, and 4 weeks post-injection. F : Quantification of lung fluorescence intensity in both groups, demonstrating significantly lower fluorescence intensity in the IRF1 overexpression group compared to the control group. G : Gross anatomy of lung tissues in nude mice, showing more metastatic nodules in the control group than in the IRF1 overexpression group. H : HE staining and IRF1-specific IHC staining of lung tissues in nude mice, confirming IRF1 overexpression in the Dox-induced group. Scale bar: 100 μm. * P < 0.05, ** P < 0.01, *** P < 0.001
