<p>Monolayer permeability is expressed as percentage flux of FITC-dextran-10 kDa fluorescence intensity, plotted on the Y-axis. Data are expressed as mean ± % SEM. ‘*a’ indicates significant increase compared to the control group; ‘*b’ indicates significant decrease compared to the IL-1β (10 ng/mL; 2 hours) treatment group. siRNA transfected groups were compared to control siRNA transfected group (n = 4; p<0.05).</p
