B, Recognition of different conformations of recombinant PAI-1 by A5 in Western blotting. C, A5 neutralized PAI-1 function in inhibiting tPA and uPA. D, Competitive binding of A5 with fluorine-containing tiplaxtinin on stable active PAI-1 assessed by 19F-NMR. E, Inhibition of proliferation of PM cells treated with PAI-1–positive ascites in vitro by 150 µg/mL A5 in biological triplicates. Human IgG served as a negative control. F, STAT3 signaling activation upon the exposure to PM ascites was suppressed by A5 as compared with IgG control. G, GSEA comparisons of HALLMARK pathway changes between CRC cells treated with A5 ( n = 2) vs. IgG ( n = 2). Pathways with an FDR adjusted P value of less than 0.05 are opacified.

Figure Lengend Snippet: (a): Western blot was used to detect the protein expression of KYSE30 cells treated with different concentrations of compounds. (b): Western blot results showed that the expression of Stat3 protein was significantly decreased after treatment with different concentrations of the compounds. (c): The expression of Smad2/3 protein was significantly decreased after treatment with different concentrations of drugs. (d): The expression of cleaved caspase3 protein was significantly increased after treatment with different drug concentrations. Data are shown as the mean±SD and were analyzed with one‐way ANOVA. (*P<0.05, **P<0.01, ***P<0.001, and ****P<0.0001, compared with the control group).

Article Snippet: After washing with TBST solution, the membrane was incubated overnight at 4 °C with the primary antibody Stat3 (1 : 2000, CST), Smad2/3 (1 : 1000, CST), GAPDH (1 : 5000, Sangon Biotech), and cleaved caspase 3 (1 : 1000, CST).
