Angiogenesis inhibitors are beneficial for the prevention and treatment of angiogenesis-dependent diseases including cancer. We examined the cytotoxic, anti-metastatic, anti-cancer and anti-angiogenic effects of diallyl trisulfide (DATS). In HT29 cells, DATS inhibited migration and invasion through the inhibition of focal adhesion kinase (FAK), extracellular signal-regulated kinase, c-Jun N-terminal kinase and p38 which was associated with inhibition of matrix metalloproteinases-2, -7 and -9 and VEGF. In human umbilical vein endothelial cells (HUVEC), DATS inhibited the migration and angiogenesis through FAK, Src and Ras. DATS also inhibited the secretion of VEGF. The capillary-like tube structure formation and migration by HUVEC was inhibited by DATS. The chicken egg chorioallantoic membrane (CAM) assay indicated that DATS treatment inhibited ex-vivo angiogenesis. We investigated the anti-tumour effects of DATS against human colon cancer xenografts in BALB/c(nu/nu) mice and its anti-angiogenic activity in vivo. In this in-vivo study, DATS also inhibited the tumour growth, tumour weight and angiogenesis (decreased the levels of haemoglobin) in HT29 cells. In conclusion, the present results suggest that the inhibition of angiogenesis may be an important mechanism in colon cancer chemotherapy by DATS.
血管生成抑制剂对预防和治疗包括癌症在内的血管生成依赖性疾病有益。我们研究了二烯丙基三硫化物(DATS)的细胞毒性、抗转移、抗癌和抗血管生成作用。在HT29细胞中,DATS通过抑制粘着斑激酶(FAK)、细胞外信号调节激酶、c-Jun氨基末端激酶和p38来抑制迁移和侵袭,这与抑制基质金属蛋白酶-2、-7和-9以及血管内皮生长因子(VEGF)有关。在人脐静脉内皮细胞(HUVEC)中,DATS通过FAK、Src和Ras抑制迁移和血管生成。DATS还抑制VEGF的分泌。DATS抑制了HUVEC的毛细血管样管结构形成和迁移。鸡胚绒毛尿囊膜(CAM)试验表明,DATS处理抑制了体外血管生成。我们研究了DATS对BALB/c(nu/nu)小鼠人结肠癌异种移植瘤的抗肿瘤作用及其体内抗血管生成活性。在这项体内研究中,DATS还抑制了HT29细胞的肿瘤生长、肿瘤重量和血管生成(降低血红蛋白水平)。总之,目前的结果表明,抑制血管生成可能是DATS进行结肠癌化疗的重要机制。
