Figure 2From: Significance of rs1271572 in the estrogen receptor beta gene promoter and its correlation with breast cancer in a southwestern Chinese populationImmunohistochemical staining of ERβ in tissues from different patients with breast cancer. Human breast cancer section were immunostained for ERβ. A) All cells were negative for ERβ staining. B) Weak ERβ staining. C) Low ERβ staining (21–40% cells were positive for ERβ staining). D) medium ERβ staining (41–60% cells were positive for ERβ staining), and high ERβ staining (>61% cells were positive for ERβ staining).Back to article page
