Epigenetic inactivation of secreted frizzled-related protein 2 in esophageal squamous cell carcinoma

Figure 7 Secreted frizzled-related protein 2 inhibits growth of tumors derived from KYSE-30 in vivo. A: A representative picture of nude mice: at week 5 nude mice injected with KYSE-30, KYSE-30/vector, KYSE30/SFRP2 and phosphate buffered saline; B: The tumor growth curves of nude mice. The growth of tumors derived from the SFRP2-transfected esophageal squamous cell carcinoma cells cells were significantly slower than those from the mock-transfected cells (^aP < 0.05).
