Figure 1: NOX expression is associated with disease progression in TRAMP mice.

(A,B) NOX1 and p67phox expression was analyzed by IHC in TRAMP prostate tissue with different stages of the disease as well as in non-transgenic mice prostate tissue as negative control. Representative photographs are presented at 100x; inset represent further magnification of a part of the photograph. Immunoreactivity (represented by brown staining) of NOX1 and p67phox was scored as described in methods. Abbreviations: NC: Negative control; LG: Low-grade; HG: High-grade; PIN: Prostate intra-epithelial neoplasia; WD: Well differentiated; MD: Moderately differentiated; PD: Poorly differentiated. *p ≤ 0.001.
