Association of High Expression of Groβ with Clinical and Pathological Characteristics of Unfavorable Prognosis in Gastrointestinal Stromal Tumors

Figure 1

Representative patterns of GROβ expression in gastrointestinal stromal tumors (GIST) tissues. ((a1), (a2)) Strong GROβ cytoplasm expression (red arrow) was detected in GIST, with GROβ immunohistochemical staining in nucleus (blue). ((b1), (b2)) Strong GROβ nucleus expression (green arrow) was detected in GIST. ((c1), (c2)) Expression of GROβ protein was negative in cytoplasm and nucleus of GIST tissue. Original magnifications: (a1), (b1), and (c1): 10x; (a2), (b2), and (c2): 40x.
