Fig. 1. Representative images showing immunohistochemical staining for pPAK4S474 and PAK4 (magnification, ×400). (A) Control image of pPAK4S474 in tonsil tissue; (B) absent nuclear staining of pPAK4S474 in RCC tissue; (C) strong nuclear staining of pPAK4S474 in RCC tissue; (D) control image of PAK4 in tonsil tissue; (E) absent nuclear staining of PAK4 in RCC tissue; and (F) strong nuclear staining of PAK4 in RCC tissue. PAK4, p21-activated kinase 4; pPAK4S474, phospho-Ser474 PAK4; RCC, renal cell carcinoma.
