Comprehensive characterization of claudin-low breast tumors reflects the impact of the cell-of-origin on cancer evolution

Abstract excerpt

Claudin-low breast cancers are aggressive tumors defined by the low expression of key components of cellular junctions, associated with mesenchymal and stemness features. Although they are generally considered as the most primitive breast malignancies, their histogenesis remains elusive. Here we show that this molecular subtype of breast cancers exhibits a significant diversity, comprising three main subgroups...
