Author Correction: EZH2 inhibition sensitizes BRG1 and EGFR mutant lung tumours to TopoII inhibitors

We wish to correct two mutations in Supplementary Table 4 of this Letter. The NCI-H460 cell line was annotated as being mutant for TP53. NCI-H460 has been verified to be TP53 wild type by several sources1. The NCI-H2009 cell line was annotated as being mutant for PIK3CA. As annotated by COSMIC (ref. 24 of the original Letter) and CCLE (ref. 25 of the original Letter), the NCI-H2009 cell line has a mutation in PIK3C3, rather than PIK3CA. The cell line is wild type for PIK3CA. The Supplementary Information of this Amendment contains the corrected Supplementary Table 4. These errors do not affect our conclusions. The original Letter has not been corrected.
