Representative images of immunohistochemical staining to detect the expression of AQP5 and AQP8 in clinical colorectal samples. (A) AQP5 immunoreactivity was detected in the cytoplasm and plasma membrane of colorectal carcinoma cells (dark brown). (B) AQP5 immunoreactivity was not detected in the adjacent normal colon epithelium. (C) AQP8 immunoreactivity was detected in the cytoplasm and plasma membrane of adjacent normal colon epithelium (dark brown). (D) AQP8 immunoreactivity was not detected in the colorectal carcinoma tissues. (Magnification: ×400).
