There was an error published in J. Cell Sci.124, 2951–2963.

In Fig. 4C, the blot representing pATM was inadvertently duplicated as representing G3PDH. The G3PDH western blot has been replaced with the correct image in the figure shown below. There are no changes to the figure legend, which is accurate. This error does not affect the conclusions of the study.

Increased γH2AX level during MC leads to cell death. Untreated or doxorubicin (600 nM)-treated 14-3-3σ-knockout HCT116 cells were cultured and harvested at indicated time points and analysed by western blot (50 μg), comet assay and immunostaining using antibodies directed against γH2AX (green). Blots were reprobed for G3PDH to confirm an equal loading of the samples. The co-staining of nuclei was performed using Hoechst 33342 (white). (A,B) Representative confocal images showing nuclear morphology and γH2AX staining in 14-3-3σ-knockout HCT116 (A) or wild-type HCT116 (B) cells after treatment for indicated time. (C) 14-3-3σ-knockout HCT116 cells were treated for 9 hours with doxorubicin after which the culture medium was replaced and cells were grown for an additional 24, 48 and 72 hours. Immunoblots of p53, phosphorylated ATM and γH2AX are shown. (D) Doxorubicin-induced DNA damage measured by alkaline comet assay. Cells were analysed by fluorescence microscopy and scored according to tail moment. Error bars represent the mean of three independent experiments±s.e.m. Scale bar: 20 μm.
