Rab27b Is a Potential Indicator for Lymph Node Metastasis and Unfavorable Prognosis in Lung Adenocarcinoma

Figure 3

Representative types of Rab27b protein expression in lung adenocarcinoma (LUAD) tissue samples and corresponding noncancerous tissue samples. (A1, A2, and A3) High cytoplasmic expression of Rab27b in an LUAD tissue sample. Red arrows show the positive staining in the cytoplasm of cancer cells. (B1, B2, and B3) Low cytoplasmic expression of Rab27b in an LUAD tissue sample. Orange arrows show the positive staining in the cytoplasm of cancer cells. (C1, C2, and C3) No expression of Rab27b in a noncancerous tissue sample. Original magnification: ×40 in A1–C1, ×200 in A2–C2, and ×400 in A3–C3.
