项目摘要
The role of vasohibin-1(VASH-1), a negative feedback regulator of angiogenesis synthesized by endothelial cells(ECs), and vasohibin-2(VASH-2) which antagonizes VASH-1 was studied. Pathological analysis revealed that VASH-1 was present in ECs in tumor vessels, which was correlated with VEGF in cancer cells, pathological grading, and proliferation rate of cancer cells. Animal models revealed that endogenous VASH-1 regulates tumor angiogenesis, but exogenous supplementation of VASH-1 further exhibited anti-angiogenic and anti-lymphangiogenic activities and inhibited tumor growth and lymph node metastasis. VASH-2 was shown in mononuclear cells infiltrating in cancer stroma as well as in cancer cells, and VASH-2 promoted tumor growth by stimulating angiogenesis.
研究了内皮细胞(ECs)合成的血管生成负反馈调节因子vasohibin-1(VASH-1)和拮抗VASH-2 (VASH-2)的作用。病理分析显示,VASH-1存在于肿瘤血管的ECs中,其与癌细胞中的VEGF、病理分级及癌细胞的增殖率相关。动物模型显示,内源性VASH-1调节肿瘤血管生成,但外源性补充VASH-1进一步表现出抗血管生成和抗淋巴管生成活性,抑制肿瘤生长和淋巴结转移。在浸润于癌间质和癌细胞的单核细胞中均发现VASH-2, VASH-2通过刺激血管生成促进肿瘤生长。
