In the version of this article originally published online, the title was listed incorrectly and two of the supplementary data files were not published in their final, revised form.
The correct title of this article is: ‘The transformics assay: first steps for the development of an integrated approach to investigate the malignant cell transformation in vitro’. This has now been corrected online.
In addition, the Supplementary Information document and Supplementary Table 2 have been updated online.
