Western blot analyses of E-cadherin and Snail in SNU719 cells treated with IL-1β. (A, B) E-cadherin expression decreases as the dose or exposure time of IL-1β increased, whereas Snail expression increased with dose or time of IL-1β. Twenty µg of protein was separated by 10% SDS-polyacrylamide gel electrophoresis and transferred to a nitrocellulose membrane. The bottom represents GAPDH, which was used as a loading control.
