摘 要:目的观察3-脱氧葡萄糖醛酮(3-DG)对新血管生长的影响。方法应用鸡胚绒毛尿囊膜(CAM)和内皮细胞体外培养的方法研究3-DG对新血管生长的影响。CAM血管生长采用单位面积血管百分比法评价;细胞增殖采用MTT法评价。结果0.1、1μg3-DG和0.1μgAGEs组均可促进CAM新生血管生成,与空白对照组比较,差异有统计学意义(P<0.05)。与内皮细胞孵育24h后,3-DG50、100、150、200和250mg/L浓度组均明显促进内皮细胞生长(P<0.05),而300、400mg/L浓度组则无促进作用(P>0.05);与内皮细胞孵育48h后,50、100、150和200mg/L浓度组均有促进内皮细胞生长的趋势,但差异均无统计学意义(P>0.05),250mg/L无作用呈下降趋势,而300和400mg/L浓度组则明显抑制内皮细胞生长(P<0.05)。形态学观察,3-DG300mg/L组与空白对照组比较,出现细胞核固缩。结论3-DG可以诱导新血管生长。Objective To observe the effect of 3-deoxyglucosone (3-DG) on angiogenesis. Methods (1) The effect of 3-DG on angiogenesis was examined in vivo by the improved chorioallantoic membrance(CAM) assay(including "the blood vessels percentage in certain area" ,a measure angiogenesis method on CAM). (2) The effect of 3-DG on proliferation of vascular endothelial cells (ECV304) in vitro was assessed by MTT assay (490 nm). Results (1) Compared with the controls,significantly angiogenesis on CAM was observed in the 3-DG (0.1,1 μg) and AGEs (0.1 μg) groups (P〈0.05); (2) Incubated with ECV304 for 24 h,in the 3-DG (50,100,150,200 and 250 mg/L) groups the proliferation of ECV30 was able to be promoted (vs control,P〈0.05),but no effect was observed in the 3-DG (300 and 400 mg/L) groups(vs control,P〉0.05); Incubated with ECV304 for 48 h,in the 3-DG(300 and 400 mg/L) groups the proliferation of ECV304 was able to be inhibited (vs control,P〈0.05),while no effect was observed in the 3-DG (50,100,150,200 and 250 mg/L) groups (vs control,P〉0.05). (3) Morphologically shrink of the core was observed in the ECV304 which was incubated with 3-DG (300 mg/L) for 48h. Conclusion The results imply that 3-DG may be an angiogenetic factor which can induce abnormal angiogenesis.
