Figure Lengend Snippet: Out of 84 human genes involved in the regulation of angiogenesis the expression of anti-angiogenic COL18A1 (endostatin), COL4A3 (tumstatin) and TIMP3 (Tissue inhibitor of metallopeptidase 3) genes are significantly upregulated as measured by Human Angiogenesis RT2 ProfilerTM PCR Array (Qiagen PAHS- 024Z).

Article Snippet: Proteins from the gel were then transferred to nitrocellulose membrane and probed for with biotinilated anti-human Endostatin (R&D Systems BAF1098, 1:1000), anti-amyloid beta precursor protein (Abcam ab32136, 1:1000), anti-DSCR1 (Sigma D6694, 1:2000) and normalized to Beta-Actin (Sigma A2228, 1:10,000).

Figure Lengend Snippet: Expression of endostatin in the three groups. (A) Agarose gel electrophoresis results of endostatin mRNA expression, as detected by reverse transcription-polymerase chain reaction in the different groups. (B) The relative mRNA level of endostatin was examined after group C had been injected with pEgr-1-endostatin plasmid for 12 h and exposed to 300 cGy/min X-ray for 48 h. Endostatin was successfully increased in the group C compared with that in groups A and B (F=380.078, P<0.001). (C) The protein level of endostatin was evaluated by western blotting. The results indicated that the expression of endostatin was significantly increased in group C compared with groups A and B (P=0.039). (D) ELISA was used to determine the plasma endostatin level, and the expression of endostatin in group C was observed to be higher than that in groups A (t=44.770, P<0.001) and B (t=42.480, P<0.001). A, control group; B, IR-treated group; C, endostatin-IR-treated group; IR, ionizing radiation; M, marker; mRNA, messenger RNA. ***P<0.001.

Figure Lengend Snippet: MVD in tumor tissues. (A) The MVD counts for each group were significantly different among the different groups (F=22.660, P<0.001). An obvious increase in MVD was observed in group B (20.970±1.410) compared with that in group A (15.890±1.476, t=7.040, P<0.001), while a significant decrease in MVD was observed in group C (6.366±0.155) compared with that in groups A (t=18.153, P<0.001) and B (t=29.120, P<0.001). (B) Tumor microvessels were identified by cluster of differentiation 31 immunohistochemistry (magnification, ×200). Comparison of the morphology of the tumor vasculature in the three groups revealed that the microvessels in the (a) endostatin-IR-treated group were more regularly distributed and had fewer giant branches than those in the (b) control and (c) IR-treated groups. A, control group; B, IR-treated group; C, endostatin-IR-treated group; IR, ionizing radiation; MVD, microvessel density. ***P<0.001.

Figure Lengend Snippet: Expression of HIF-1α in tumor tissues. (A) Agarose gel electrophoresis results of HIF-1α mRNA expression, as evaluated by reverse transcription-polymerase chain reaction in different groups. (B) Relative levels of HIF-1α mRNA in different groups. The difference was statistically significant in the three groups: Groups A and B (t=8.961, P<0.001); groups A and C (t=5.339, P=0.001); groups B and C (t=12.930, P<0.001). (C) The protein level of HIF-1α was analyzed by western blotting. A higher average optical density value for HIF-1α was observed in group B compared with that in groups A and C. The difference was statistically significant (P=0.046). (D) Immunohistochemistry assessment indicated that the expression of HIF-1α was (a) moderate in the control group; (b) strong in the IR-treated group; and (c) weak in the endostatin-IR-treated group (magnification, ×200). A, control group; B, IR-treated group; C, endostatin-IR-treated group; IR, ionizing radiation; M, marker; mRNA, messenger RNA; HIF, hypoxia-inducible factor. ***P<0.001.

(A) Agarose gel electrophoresis results of VEGF mRNA expression in tumor tissues, as detected by reverse transcription-polymerase chain reaction. (B) A significant difference was observed in the three groups (F=119.691, P<0.001). Compared with group A (0.530±0.0444), the relative VEGF mRNA expression was increased in group B (0.653±0.0727, P=0.001) but decreased in group C (0.250±0.0359, P<0.001).
