Doxorubicin-induced cell death requires cathepsin B in HeLa cells
Résumé
The cysteine protease cathepsin B acts as a key player in apoptosis. Cathepsin B mediated cell death is induced by various stimuli such as ischemia, bile acids or TNFα. Whether cathepsin B can be influenced by anticancer drugs, however, has not been studied in detail. Here, we describe the modulation of doxorubicin induced cell death by silencing of cathepsin B expression. Previously, it was shown that doxorubicin, in contrast to other drugs, selectively regulates expression and activity of cathepsin B.
