Figure 1.
COX2 is expressed in the hyperplastic PTGs from hemodialysis patients. (A) COX2 immunoreactivity in PTGs with diffuse hyperplasia (A1, A4), early nodular hyperplasia (A2, A5), and nodular hyperplasia (A3, A6). Magnifications: ×5 in A1 through A3; ×400 in A4 through A6. (B) Immunoblot of diffuse hyperplasia and nodular hyperplasia PTGs using antibodies for COX2 and β-actin as a loading control. Quantitative analysis result was expressed as COX2/β-actin protein ratio. bP < 0.01 versus diffuse hyperplasia tissue.
