Immunohistochemical analysis of furin expression in papillary thyroid cancer (PTC) TMA. Representative examples of tumors showing (A) low expression and (B) high expression of furin. (20×/0.70 objectives on an Olympus BX 51 microscope (Olympus America Inc, Center Valley, PA, USA) with the inset showing a 40× 0.85 aperture magnified view of the same TMA spot; scale bar in A and B = 200 μm). (C) Kaplan–Meier survival analysis for the prognostic significance of furin expression in PTC. PTC patients with overexpression of furin had reduced disease‐free survival at 5 years compared to tumors showing low expression of Furin (P = 0.0003).
