The cover shows the results of an unsupervised two-dimensional hierarchical clustering analysis of the 5,000 most variable genes classifying breast tumors into ER⁺, HER2⁺, or triple-negative (ER⁻, PR⁻, HER2⁻) subtypes. The analysis was performed on 800 breast tumors obtained from the Karolinska Institutet, Sweden. The RAS gene expression signature was high in the triple-negative subtype and low in the ER⁺ subtype. For details, see the article by Di Cosimo and colleagues on page 49 of this issue.
