In the version of this article initially published, the figure showed blocking arrows from HOXA9 to BRCA1 and PTEN, but these should have been regular arrows. PIP3 and AKT should have been located close to the membrane, instead of the cytoplasm. Integrin proteins should have been heterodimers rather than homodimers, and the protein β-catenin should not have had a phosphorylated residue. The errors have been corrected in the HTML and PDF versions of the article.
