Figure Lengend Snippet: Knockdown of LEF1 interferes with PAAD cell malignant progression and neovascularization by inhibiting Notch1 and NF-κB signaling pathways. A–F, Immunofluorescence experiments and fluorescence intensity analysis: the relative fluorescence level of Notch1 and P65 decreased in AsPC-1/LEF1 and BxPC-3/LEF1. G–M, WB assay results and quantitative analysis: the total Notch1, NICD, Hes1, Hey1, and Jagged1 protein levels and the p-P65/P65 ratio were decreased in AsPC-1/LEF1 and BxPC-3/LEF1 (n = 3, * P <0.05).

Article Snippet: The first antibodies were as follows: LEF1 (ab137872, 1:1000, Abcam), proliferating cell nuclear antigen (PCNA, ab29, 1:1000, Abcam), MMP-2 (4022S, 1:1000, CST), MMP-9 (3852S, 1:1000, CST), BAX (2772S, 1:1000, CST), Bcl-2 (15071S, 1:1000, CST), Cleaved caspase-3 (9661S, 1:1000, CST), Cleaved caspase-9 (9509S, 1:1000, CST), vascular endothelial growth factor-A (VEGFA, ab214424, 1:1000, Abcam), total Notch1 (ab52627, 1:1000, Abcam), NICD (4147, 1:1000, CST), Hes1 (ab71559, 1:1000, Abcam), Hey1 (ab235173, 1:1000, Abcam), Jagged1 (ab300561, 1:1000, Abcam), P65 (ab32536, 1:1000, Abcam), p-P65 (3033S, 1:1000, CST), GAPDH (5174S, 1:5000, CST), HRP-anti-Rabbit (A0362, 1:1000, Beyotime), HRP-anti-Mouse (A0350, 1:1000, Beyotime).

Figure Lengend Snippet: 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).
