Figure 2

Detail of typical GSTP1 staining pattern in prostatectomy: benign glands strongly positive (A), PIN basal cell layer positive with negative luminal cells (B), and PCa completely negative (C). Detail of heterogeneous GSTP1 staining in benign glands in prostatectomy: strong positivity in basal cell layer and luminal cells (D), intermediate positivity in luminal cells and strong positivity in basal cell layer (E), and strong positivity in basal cell layer and negative luminal cells (F).
