Subsequently to the publication of this article, the authors have realized that the article contained several errors in need of correction. Firstly, the penultimate sentence in the “IHC evaluation” subsection of the Materials and methods on p. 4949–4950 that reads as “Patients with high TNF-α and low p38MAPK expression and patients with low TNF-α and high p38MAPK expression…” should have read as follows (changes highlighted in bold): “Patients with high TNF-α expression alone and patients with high p38MAPK expression alone were included in the TNF-α high-expression group and the p38MAPK high-expression group, respectively.”

Secondly, Fig. 2E-H in Fig. 2 should have been presented consistently with Fig. 3E-H in view of the fact that the high expression of TNF-α alone or the high expression of p38MAPK alone was compared with low expression of both TNF-α and p38MAPK. The revised version of Fig. 2, containing the correct presentation of Fig. 2E-H, is shown opposite. Note that the figure legend has not been altered as a consequence of these changes.

Finally, the labels written as “high and low” in Fig. 3E and F should have been written as “TNF-α high”, and the labels written as “low and high” in Fig. 3G and H should have been written as “p38MAPK high”, to make them tally with the description of the results in the article and be consistent with the figure legend. The corrected version of Fig. 3 is shown on the third page of this corrigendum. No modification of the description of the results relating to Figs. 2 and 3 has occurred as a consequence of these changes.

Note that none of these corrections affect the main conclusions reported in the paper. Nevertheless, the authors apologize to the readership of the Journal for any inconvenience caused.
