Knockdown of LEF1 enhances immune response in mice. A and B, Immunofluorescence results and percentage of positive cells: the fluorescence intensity of PD-L1 in tumor tissues of sh-LEF1 group decreased. C and D, HE staining results and necrotic cell count showed that the proportion of cell necrosis in sh-LEF1 tumor tissue was decreased. E–H, ELISA results and content statistics showed that knockdown of LEF1 downregulated the contents of TGF-β1, IL-10, PD-L1, and CCL2 in sh-LEF1 tumor tissues. I–O, WB assay results and quantitative analysis showed decreased levels of total Notch1, NICD, Hes1, Hey1, and Jagged1 proteins in tumor tissues, and a decreased p-P65/P65 ratio (n = 6, * P <0.05).
