This premise needs further investigation, but the current study already showed that in human BC, ColXVIII expression was particularly strong in collectively invading cells (Figure 1G) and in the invading CK14+ basal cells in MMTV-PyMT tumors (Supplemental Figure 10B), and that depletion of ColXVIII could also reduce the migration of both basal and luminal human BC cells (Supplemental Figure 14, G and H). The gene discussed is KRT14; the disease is breast cancer.
