Moreover, Triple-Negative A (basal A) lines are rich with basal markers such as integrins (ITGA6, ITGB4/6), cytokeratin (KRT4/5/6A/6B/13/14/15/16/17), LAMC2, LAMB3, S100A2, TRIM29, ANXA8, SLPI, BNC1, COL17A1, MET, CD10/14/58/59, LYN, thus are known as basal-like tumor and resemble the core basal tumor subtype. The gene discussed is KRT4; the disease is neoplasm.
