PPAR-γ Ligand Inhibits Nasopharyngeal Carcinoma Cell Proliferation and Metastasis by Regulating E2F2

Figure 1

E2F2 and PPAR-γ protein expression in nonkeratinizing nasopharyngeal carcinoma (NPC) and nasopharyngitis (NPG) tissues. Immunohistochemistry was performed to detect E2F2 and PPAR-γ protein expression in nonkeratinizing NPC tissues (a, b) and NPG tissues (c, d). Scale bar, 50 μm (e, f). The immunohistochemistry data were analyzed semiquantitatively to determine the E2F2 and PPAR-γ expression levels in nonkeratinizing NPC and NPG tissues. Data are shown as means ± standard deviations. P <0.01.
