This article has been retracted on request by the corresponding author. The authors have identified errors affecting several figure panels in which original data were processed inappropriately such that the panels in Fig. 4: “Expression of the cell cycle- and apoptosis-related proteins treated with KN-93 in choriocarcinoma cells measured by Western blot analysis. Choriocarcinoma cells were treated with KN-93, and cell lysates were harvested after 48 h. Western blot analysis was performed with a series of antibodies (cyclin A, cyclin D1, Bcl-2, and cleaved caspase-3). Control cells were treated with vehicle alone. The amount of protein was normalized by comparison to levels of GAPDH” do not accurately report the original data. The other authors were not involved in making these figures. The corresponding author, Dr. Takai, sincerely apologizes to the co-authors and the scientific community for any inconvenience that this might cause.
