STAT3 inhibitor blocked the effect of CLCF1 and FSGS serum on Palb. Isolated rat glomeruli were pre-incubated with STAT3 inhibitor Stattic (0.001–1µM) for 15 minutes followed by addition of CLCF1 (10ng/mL). In separate experiments, glomeruli were pre-incubated with Stattic (0.1 or 1µM) for 15 minutes followed by FSGS serum (20µL/mL) for 15 minutes at 37°C. Pre-treatment of glomeruli with Stattic (0.05–1µM) significantly blocked the effect of CLCF1 (P<0.001 vs.CLCF1 alone). Pre-incubation with Stattic (1µM) blocked the effect of FSGS serum on Palb. (#, P<0.001 vs. FSGS alone). N=15 glomeruli from 3 rats (5 glomeruli from each rat) in each group.
