After the publication of the article, the authors realized that they had inadvertently included the incorrect data for the ‘siDOR+5-fu group’ in the flow cytometric plots featured in Fig. 3A. A new version of Fig. 3 is provided, which contains the correct data for the ‘siDOR+5-fu group’ experiment.

The authors regret this error, and apologize to the readers for any inconvenience caused.

Effects of DOR gene silencing (siDOR) on the apoptosis of BEL/FU cells. (A) Flow cytometric analysis using Annexin V-fluorescein isothiocyanate double staining. (B) Histogram presenting the apoptotic rates of BEL/FU cells. Data are from three independent experiments and are presented as the mean ± standard deviation. **P<0.01, vs. siControl. DOR, δ opioid receptor; BEL/FU, BEL-7402/5-fluorouracil; PI, propidium iodide.
