Figure 4: Expression of ANXA1 in different molecular subtypes of breast cancer. A. Luminal A B. luminal B breast cancer fail to express ANXA1 in cancer cells. C and D. Triple-negative breast cancer. Some patients display negative or low level of ANXA1 expression (C) others showed high ANXA1 expression (D). E and F. HER2-positive breast cancers with either negative (E) or positive expression (F) of ANXA1. E. Histogram displaying the percentage of patients with high and low expression of ANXA1 in each molecular subtype of breast cancer. Magnification: 20X (A-F).
