[Retracted] Mechanism of cell death induced by silica nanoparticles in hepatocyte cells is by apoptosis

Following the publication of this article, a concerned reader drew to the Editor's attention that the image showing silica nanoparticles in Fig. 1 on p. 906 had also been used to show the same data in another paper published by the same research group in <i>International Journal of Molecular Medicine</i>. Upon performing a separate investigation of the data in this paper in the Editorial Office, it also came to light that flow cytometric plots featured in Fig. 3 on p. 908 had originally been included in a paper featuring some of the same authors that had already been published in <i>International Journal of Nanomedicine</i>, and western blot data featured in Fig. 7 on p. 910 were originally included in another paper featuring some of the same authors in the journal <i>Stem Cell Research & Therapy</i>. Given the apparent re‑use of the abovementioned data in this article from previously published papers, the Editor of <i>International Journal of Molecular Medicine</i> has decided that this article should be retracted from the Journal. 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 caused.
