Expression of EZH2 in laryngeal squamous cell cancers. The tumor tissues and paracancerous tissues in the tissue microarray were stained using immunohistochemistry. (A and C) Representative and paracancerous tumor tissues, repectively; (B and D) Representative and paracancerous tumor tissues, repectively of another patient. The immunohistochemical staining was observed under a fluorescence microscope (magnification, ×100). The level of EZH2 expression in the tumor tissues was significantly increased compared with the paracancerous tissues. EZH2, enhancer of zeste 2 polycomb repressive complex 2 subunit.
