Abstract
Correction for ‘Enhancing the anti-ovarian cancer activity of quercetin using a self-assembling micelle and thermosensitive hydrogel drug delivery system’ by Guangya Xu et al., RSC Adv., 2018, 8, 21229–21242.
The authors regret that Fig. 8A and C in the original article contained errors, due to incorrect data sets being used for the image preparation. The correct version of Fig. 8 is shown below.
Fig. 1. Tunnel assay. The tumor tissue sections of the normal saline (NS) treated group (A), empty hydrogel (EG) treated group (B), free quercetin (FQ) treated group (C), Qu-M (QM) treated group (D), and Qu-M–hydrogel composite (QMG) treated group (E) were stained with Tunnel for the cell apoptosis assay, indicating that inducing apoptosis may be one of the anti-tumor mechanisms of the Qu-M–hydrogel composites (QMGs), Qu-M (QM), and free quercetin (FQ) in vivo.
In addition, on page 21237 of the original manuscript in the section titled “3.3.4 Induction of tumor cell apoptosis in vivo”, a sentence should be corrected. “The apoptotic index in Qu-M–hydrogel composites, Qu-M, free quercetin (Free-Qu), empty hydrogel and normal saline (NS) were 72.7% ± 6.34%, 43.23% ± 4.68%, 28.23% ± 3.23%, 2.14% ± 0.57%, and 1.31% ± 0.43, respectively,” should be “The apoptotic index in Qu-M–hydrogel composites, Qu-M, free quercetin (Free-Qu), empty hydrogel and normal saline (NS) were 72.7% ± 6.34%, 43.23% ± 4.68%, 23.41% ± 5.37%, 2.14% ± 0.57%, and 1.52% ± 0.35, respectively”.
The Royal Society of Chemistry apologises for these errors and any consequent inconvenience to authors and readers.
