Cx treatment and measurement of tumor development are described in the Methods section. The graph represents the tumor volume of control (n=6) and Cx-treated (n=6) mice. Cx showed an anti-tumor effect compared with control (p0.05). For bioethical reasons, the experiment was stopped at 19th day. Bars represent standard errors. Wilcoxon signed rank test p0.05.,Cx inhibits microvascular density of a murine A/J mammary tumor (TA3-MTXR).,Histological sections stained with Arteta were visualized at 400 in an optical microscopy and blood vessels were counted. Left panel shows a representative section of untreated primary tumor (A) or Cx-treated (B). Blood vessels were counted (C) and a statistical significance was found (*: p0.0001). Right panel shows a representative section of untreated lung metastasis (D) or Cx-treated (E). Blood vessels were counted (F) and a statistical significance was found (*: p=0.0031). Blood vessels are represented by black arrows.,Cx decreases proliferation, VEGF production and promotes apoptosis of a murine A/J mammary tumor (TA3 MTXR),. Tumor samples showed a decreased proliferation in Cx-treated group (B), when compared with control group (A).
