Correction to: Cancer Gene Therapy https://doi.org/10.1038/s41417-019-0094-x, published online 12 June 2019

After publication, an issue with Figure 1E was discovered. The authors rechecked their raw data and found that when they took photos of the histochemical results of renal cancer tissues of different grades, they accidentally mixed up the histochemical slide of grade I/II as grade III/IV, and took photos of the same slide twice, resulting in the overlap. However, the error did not quantitatively affect any of the results and overall conclusions drawn in the original manuscript.

The correct Figure 1E accompanies this correction.

The original article has been corrected.
