G9a expressions clinically correlate with metastasis-related genes. A. Representative microphotographs of immunohistochemical staining of G9a, GADD34, and Sprouty4 in matched specimens of primary ovarian tumors and metastases. Scale bar: 100 μm. B. mRNA expression scatter diagrams of G9a versus DUSP5, SPRY4 or PPP1R15A. Red dots represent expression of indicate genes from specimens in a dataset; regression lines shown on plot. The three left plots were made from GSE9891, and the three right plots were made from GSE12471.
