Article Title: Deciphering the CAF-LCN2 axis: Key to overcoming anti-PD-L1 immunotherapy resistance in lung cancer

doi: 10.3892/ijmm.2026.5735

Figure Lengend Snippet: Influence of LCN2 on the growth of lung cancer in mice. (A) Simplified flowchart outlining the establishment of an anti-PD-L1 immunotherapy tolerance model in mice with lung cancer. (B) Western blot analysis of LCN2, COL1A1 and THY1 expression in tumor tissues from drug-resistant and drug-sensitive mice. (C) Immunohistochemical detection of LCN2, COL1A1 and THY1 expression in tumor tissues from drug-resistant and drug-sensitive mice (scale bar, 100 µm). (D) Establishment of a model for anti-PD-L1 immunotherapy in LCN2-silenced mice. (E) Evaluation of LCN2 mRNA expression in tumor tissues after LCN2 gene intervention in mice. (F) Assessment of LCN2 protein expression in tumor tissues following LCN2 gene intervention in mice. (G) Tumor size in LCN2 gene intervention mice (n=10 in each group). *P<0.05, **P<0.01 and ***P<0.001. Unpaired two-tailed Student's t-test was used for (B) and (C) and one-way ANOVA with Tukey's multiple comparisons test was used for (E) and (G). LCN2, lipocalin 2; PD-L1, programmed death-ligand 1; sh-, short hairpin; NC, negative control; COL1A1, collagen α-1(I) chain; THY1, Thy-1 membrane glycoprotein; i.p., intraperitoneal.
