IDE effect on ubiquitin system. A, Western blotting of the overall poly-ubiquitinated proteins content in lysates from IDE-silenced SHSY5Y. IDE inhibition is accompanied by a significant reduction of the poly-ubiquitinated proteins compared with untreated or scrambled cells. A representative immunoblot of six independent experiments is shown. B, Western blotting analysis of co-immunoprecipitation sample in SHSY5Y. Immunoaffinity purification shows that IDE interacts with ubiquitin and 26S proteasome in SHSY5Y neuroblastoma cells. (Ctrl indicates the whole lysate.)
