Rab27b Is a Potential Predictor for Metastasis and Prognosis in Colorectal Cancer

Figure 2

Representative images of Rab27b protein expression in colorectal cancer (CRC) tissues and corresponding noncancerous tissues with tissue microarray (TMA). A1 and A2: positive immunohistochemical (IHC) staining of Rab27b protein in CRC sample. Red arrows show positive staining in the cytoplasm of cancer cells. B1 and B2: positive IHC staining of Rab27b protein in CRC sample. Yellow arrows show positive staining in the nuclei of cancer cells. C1 and C2: negative IHC staining of Rab27b protein in matched noncancerous tissue sample. Green arrow shows negative staining in noncancerous cell (epithelial cell). Original magnification ×40 in A1, B1, and C1; ×400 in A2, B2, and C2.
