AIM: To investigate the angiogenesis effect and protective mechanism of cordycepin on rhesus macaque choroid- retinal endothelial ( RF/ 6A) cell line cultured in high glucose condition.
METHODS: Cultured RF/ 6A cells were divided into normal control group, high glucose group and high glucose (HG) + different concentration cordycepin groups (HG+ 10μ g/ mL group, HG+ 50μ g/ mL group, HG+ 100μ g/mL group). The cell proliferation was assessed using cholecystokinin octapeptide dye after treated for 48h. The cell migration was investigated by a Transwell assay. The tube formation was measured on Matrigel. Furthermore, the impact of cordycepin on high glucose - induced activation of VEGF and VEGF receptor 2 (VEGFR-2) was tested by Western blot analysis.
RESULTS: Compared with normal control group, cell viability markedly increased in high glucose group ( P <0. 05). Cordycepin inhibited RF/ 6A cell proliferation in a dose- dependent fashion: 10. 2 ± 0. 9%, 23. 4 ± 1. 5% and 31. 1±1. 2% inhibition as the concentrations of cordycepin were 10, 50 and 100μ g/ mL, respectively. The difference had statistically significant (P<0. 05) compared with high glucose group. The number of cell migration were 55. 6±2. 70, 87. 4 ± 2. 40, 65. 4 ± 2. 7, 57. 8 ± 2. 38, 62. 4 ± 2. 77 in normal control group, high glucose group and HG+10μ g/mL group, HG + 50μ g/ mL group, HG + 100μ g/ mL group respectively. Migration of RF/ 6A conspicuously increased in high glucose group ( P < 0. 05) compared with normal control group; while showing a gradually reducing trend with the increase of cordycepin dose and a statistically significant difference compared with high glucose group (P<0. 05). The number of tube formation were 18. 7±2. 08, 25. 7 ± 1. 52, 19. 9 ± 1. 57, 16. 3 ± 2. 51, 5. 67 ± 1. 72 in the abovementioned group. Similarly showing a gradually reducing trend with the increase of cordycepin dose and a statistically significant difference with high glucose group (P< 0. 05). In addition, the number of tube formation of RF/ 6A in high glucose group significant increased compared with normal control group ( P < 0. 05 ). The expression of VEGF and VEGFR-2 dramaticlly increased in high glucose group vs normal control group, oppositely gradually decreased with the increase of cordycepin concentrations, and had a statistically significant difference vs high glucose group (P<0. 05).
CONCLUSION: Cordycepin can suppress the proliferation, migration and tubu formation of RF/ 6A in high glucose condition, might via inhibiting expression of VEGF and VEGFR-2.

Objective To investigate the effect of blocking VEGF expression on the radiation sensitivity of esophageal cancer cell line TE-1 in vivo. Methods 32 male Balb/c/nu nude mice were randomly divided into four groups, including control group, radiation group, anti-VEGF group, and anti-VEGF + radiation group. The anti-VEGFcDNA cells were subcutaneously injected into the paw pats of mice (2 × 106/100 μl). The subcutaneous tumors were irradiated with 18 Gy of 60Co y-rays when the diameter of tumors varied from 0. 8 to 1.0 cm. The volume of the tumors was measured before and after irradiation, respectively. The expression level of VEGF mRNA and protein were examined by RT-PCR and Western blotting, respectively. Apoptotic cells were detected by electron micrographs. Results Latent period of the tumor formation of anti-VEGF group was lengthened compared with other groups(t = 13. 898,P <0.01 ). The volumes of tumor in anti-VEGF group [ ( 1207. 50 ± 97.07 ) mm3 ] and anti-VEGF +radiation group [ ( 1057. 5 ± 91.50 ) mm3 ] were not statistically different post-irradiation ( t = 1. 124, P >0.05 ) , but smaller than those in control group [ ( 5442. 50 ± 185.08 ) mm3 ] and radiation group [ (2922. 50 ± 152. 773)mm3 ] with statistical differences( t = 9. 475-21. 238, P < 0. 01 ). The expression level of endogenous VEGFmRNA and protein in anti-VEGF group and anti-VEGF + radiation group were statistically different from control group and radiation group (F = 387.394, 13.519, P < 0.01 ).Conclusions Antisense VEGF could inhibit the proliferation of esophageal cancer cell in the nude mice.Effect of blocking VEGF expression before irradiation on esophageal cancer xenografts might be limited.
