FIGURE 4.
miRNA expression according to breast cancer subtype. Each box plot represents relative miRNA expression in four subtypes of breast cancer: A, Luminal A (estrogen receptor [ER]+, progesterone receptor [PR]+ and human epidermal growth receptor [HER‐2]‐). B, Luminal B (ER+, PR+, and HER‐2+). C, HER‐2 (ER‐, PR‐, and HER‐2+). D, Triple negative breast cancer (ER‐, PR‐, and HER‐2‐)
