From: DEK over expression as an independent biomarker for poor prognosis in colorectal cancer
Immunohistochemical staining of DEK protein in colorectal cancer, adenoma, and normal mucosa. (A) DEK is absolutely negative for DEK protein in normal colorectal mucosa (Original magnification, ×100). (B) DEK is positive in the dysplastic cells of colorectal adenomas (Original magnification, ×200). (C) DEK is negative in colorectal cancer without lymph node metastasis (Original magnification, ×200). (D) DEK is strongly positive in the cancer cells of colorectal cancer with lymph node metastasis (Original magnification, ×200). (E) DEK is positive in the signet ring cells of colorectal cancers. (F) DEK is strongly positive in the metastatic cancer cells (arrows) in lymph node (Original magnification, ×100).
