The authors were recently made aware of some confusion regarding Figure 4 in this publication.

Figure 4
figure 1

The distributions of NCL and MMP7 in lung cancer cells in vitro and in vivo. (a) The 5-μm slices of paraffin-embedded specimens were prepared for IHC and immunoflurescent staining by using anti-c23 and anti-MMP7 antibodies. (b) NCL and MMP7 expression levels in lung tumor tissues of K-rasG12D lung cancer mice. Two consecutive sections were stained at different times to confirm indicated protein expression in the lung. (c) Fixed H1299 and A549 cells were immunofluorescently co-stained by antibodies targeting NCL and MMP7. (d) The whole cell (W), cytosolic (Cy), nuclear (Nu), nucleoplasmic and nucleolar fractions were prepared for western blotting.

In Figure 4, the authors provide two groups images of NCL and MMP7 from the same mice but consecutive sections. However, the labeling has led some readers to incorrectly conclude that images of NCL and MMP7 are from two different mice. Please see a relabeled image and new figure legend for clarification.

The authors wish to apologize to the readers and publisher for any confusion.
