Of interest, six proteins (FOXA1, ERBB2, MAPT, NAT1, PHGDH, KRT5) and one protein (PHGDH) overlapped between PAM50 and the differentially expressed proteins between basal-like and luminal-like subtypes in microdissected tumor epithelium and stroma, respectively. The gene discussed is MAPT; the disease is neoplasm.
