In the article titled “Effect of High, Medium, and Low Molecular Weight Hyaluronan on Inflammation and Oxidative Stress in an In Vitro Model of Human Nasal Epithelial Cells” [1], there was a duplication of bands and undeclared splicing in the Western Blots. After this was raised on PubPeer, the following concerns were confirmed: (i)Figure 1(a) β-actin lanes 1 and 2 appear to be the same as Figure 4 β-actin lanes 1 and 2. They represent the same conditions (untreated cells and rh-IL-17A), but the duplication was not declared. Figure 1(a) β-actin lanes 1-3 are also the same as Figure 2 β-actin lanes 1-3, though the latter has been compressed horizontally to about 70% of the width. The third lane is not the same experiment.(ii)Figure 1(a) pERK lanes 1 and 2 are the same as Figure 3(b) pERK lanes 1 and 2, and they appear to represent the same conditions.(iii)Figure 1(b) β-actin lanes 1 and 2 are the same as Figure 3(b) β-actin lanes 1 and 2. Figure 1(b) pIκBα lanes 1 and 2 are the same as Figure 3(b) pIκBα lanes 1 and 2. However, the ratios reported in the respective bar charts above the blots are quite different.(iv)Figure 2(b) β-actin lanes 1 and 2 are the same as Figure 4(b) lanes 1 and 2, though the latter has been compressed horizontally to about 70% of the width.

The authors apologized for the confusion and said this was due to inadvertent human error. They prepared a new set of figures, which have no duplication. A declaration of splicing between the bands is included in the legends of Figures 1(a) and 2(b). The corrected figures, as approved by the editorial board, are as follows:
