Effect of Id‐1 inactivation on anticancer drug‐induced apoptosis. (a), (c) Differential Id‐1 expression between CNE1 cells expressing high and low levels of Id‐1. Two Si‐RNA sequences targeted to Id‐1 (Si‐Id‐1; Si‐Id‐1‐2) and control sequence were transfected with LipofectamineTM 2000 in CNE1 cells, respectively. (b), (d) Western blotting analysis of Id‐1, PARP and Bax expression in response to anticancer drugs for 24 h.
