In the version of this article initially published, in Fig. 1b, the MM control images for HPAF-II incorrectly displayed duplicates of the BxPC-3 DMSO control images from Fig. 2h, and in Extended Data Fig. 2a, the color-coding of the ‘basal’ and ‘CQ’ bars for the Pa04C cell line, DMSO condition, was erroneously switched. The errors have been corrected in the HTML and PDF versions of the article.
