Corrigendum to “Effect of High, Medium, and Low Molecular Weight Hyaluronan on Inflammation and Oxidative Stress in an In Vitro Model of Human Nasal Epithelial Cells”

الملخص EN

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.
