Subsequently to the publication of the above
article, a concerned reader drew to our attention that the data
panel shown in Fig. 7A for the 400 μM isoquercitrin experiment had
previously appeared in Fig. 4A in another article published in the
journal International Journal of Oncology [Tang B, Li Y,
Yuan S, Tomlinson S and He S: Upregulation of the δ opioid receptor
in liver cancer promotes liver cancer progression both in
vitro and in vivo. Int J Oncol 43: 1281–1290, 2013],
indicating that results that were purported to have been obtained
under different experimental conditions had been derived from the
same original source. Furthermore, concerns were also raised
regarding the originality of some of the other data belonging to
this figure.
Given the errors that were identified in the
compilation of Fig. 7 in this article, the Editor of Oncology
Reports has decided that this article should be retracted from
the publication owing to a lack of overall confidence in the
presented data. The authors were asked for an explanation to
account for these concerns, but the Editorial Office did not
receive a reply. The Editor apologizes to the readership for any
inconvenience that might result from the retraction of this
article.
