Overexpression of Growth-Related Oncogene-β Is Associated with Tumorigenesis, Metastasis, and Poor Prognosis in Ovarian Cancer

Figure 1

Representative immunohistochemistry (IHC) images showing expression of GRO-β in tissue microarray sections of ovarian cancer. (a1) and (a2) show strong positive staining in the cytoplasm. (b1) and (b2) show weakly positive staining in the cytoplasm. (c1) and (c2) show a negative IHC reaction in benign ovarian tumor. Original magnification was ×40 for (a1), (b1), and (c1) and ×400 for (a2), (b2), and (c2).
