The authors regret that there were two errors in this article. One error was in Figure 4A. During the course of revision, the fluorescence figure of ROS detection in dioscin group (Dox 5μM + Dioscin 200ng/mL) H9C2 cells was accidently wrong used.
The other error was in Figure 7A. The fluorescence figure of ROS detection in Dox H9C2 cells was accidently wrong used. We have provided correct Figure 4A and 7A, which showed no influence to the reported data.
The authors would like to apologise for any inconvenience caused.
Correct Figure 4A. Effects of dioscin on intracellular ROS level in H9C2 cells treated by DOX.
Correct Figure 7A. Effects of dioscin on ROS level in DOX-treated H9C2 cells with transfection of miR- 140–5p mimic.
