[Corrigendum] Tumor necrosis factor‑α triggers opposing signals in head and neck squamous cell carcinoma and induces apoptosis via mitochondrial‑ and non‑mitochondrial‑dependent pathways

Following the publication of the above article, an interested reader drew to the Editor’s attention that a number of western blots in the paper appeared to contain incorrectly assembled data. First, comparing the F. Length (full‑length) Caspase 3 blots in Fig. 1F with the p‑ASK1 blots in Fig. 2C revealed that they were remarkably similar after horizontally flipping one set of the bands. In addition, the cytochrome c (Cyt. C) bands in Fig. 1F were similarly found to be remarkably similar to the IκBα blots in Fig. 2A, again after horizontal flipping of one set of the bands. Finally, it was noted that the β‑actin bands in Fig. 5C were very similar to the blots included in Fig. 3B to show the Tom20 data. After having examined the raw data underling these figures (which were also presented to the Editorial Office for our inspection), the authors realized that data in Figs. 1, 2, 3 and 5 were inadvertently assembled incorrectly in these figures. The revised versions of Figs. 1, 2, 3 and 5 are shown on the subsequent six pages. Specifically, in Fig. 1F, the blot for Cyt. C was incorrectly chosen; in Fig. 2A, the blot for IkBα was incorrectly chosen; in Fig. 3B, the blot for Tom20 was incorrectly chosen; and in Fig. 5C, the β‑actin blots shown to represent the gels for both the treated and control CLS‑354 and RPMI 2650 cells were incorrectly placed in this figure. These data have all been replaced with the correct data in the figures shown subsequently in this Corrigendum. The authors regret that the errors in Figs. 1F, 2A, 2C, 3B and 5C went unnoticed in the published versions of these figures in this paper, although note that these errors did not influence either the validity of the published data or the conclusions described in the article. The authors are grateful to the Editor of International Journal of Oncology for allowing them the opportunity to publish this Corrigendum. All the authors agree with the publication of this Corrigendum, and apologize to the readership for any inconvenience caused.
