Figure 5From: PAM50 Breast Cancer Subtyping by RT-qPCR and Concordance with Standard Clinical Molecular Markers Relative transcript abundance for ESR1 , PGR , and ERBB2 in the Basal-like subtype. There was no difference (p > 0.05) in (A) ESR1, (B) PGR, or (C) ERBB2 expression by qPCR in Basal-like tumors, regardless of being called triple-negative or non-triple negative by IHC/CISH.Back to article page
