Figure Lengend Snippet: UCN regulates the immune microenvironment and promotes ccRCC progression. ( A ) Schematic illustration of the mouse xenograft tumor model experimental design. ( B – E ) Tumor growth analyses demonstrate reduced tumor volume and weight across different experimental groups, with notable suppression in sh UCN +IgG2a and sh UCN +PD-1 groups. ( F ) Gating strategy for tumor-infiltrating lymphocytes. Representative flow plots showing the identification of Live/CD45+ cells, T cells (CD3+), CD4+ and CD8+ subsets, as well as Tregs and PD-1+ cells. ( G ) Flow cytometry analysis unveils substantial alterations in immune cell subsets in the tumor immune microenvironment. ( H , I ) Representative mIHC staining of tumors (green: CD8, red: Foxp3, blue: DAPI; scale bar, 50 μm.) ( I ) The column diagram showing the counts of spots with CD8+ T cells and Tregs in tumor slides. Data presented as Mean ± SEM. One-way ANOVA was used in ( E , G , I ). * p < 0.05; ** p < 0.01; *** p < 0.001; **** p < 0.0001.
Article Snippet: Human ccRCC cell line 786-O (Accession Number: CVCL_1051) and mouse ccRCC cell line Renca (CVCL_2174) were obtained from American Type Culture Collection (ATCC) (Manassas, Virginia) and cultured in RPMI 1640 medium (Procell, Wuhan, China) containing 10% fetal bovine serum (Procell, China) and Penicillin–Streptomycin (Procell, China).
