Following publication of the original article [1], the authors found that there were some mistakes in the data for images of HE staining, and then replicated experiments and histological observations were performed again. The correct Fig. 5 has been provided in this Correction. The conclusion of the study remains intact after the replacement of these images.

The incorrect Fig. 5 is:

Fig. 5
figure 1

PVT1 depletion ameliorates COPD in rats. A Representative images of HE staining for histological observation of rat lung tissues of each group. B-D RT-qPCR for determining expression of PVT1 (B), miR-30b-5p (C) and BCL2L11 (D) in rat lung tissues. E Measurement of BALF protein concentration. F, G ELISA for examining concentrations of IFN-γ and TNF-α in the serum of rats. **p < 0.01, ***p < 0.001; ##p < 0.01 vs. COPD + LV-NC group
