血管生成拟态(VM)在结直肠癌转移中起重要作用,缺氧和上皮-间充质转化(EMT)都是VM发生的必要条件。在本研究中,HIF-1α在Vm阳性的结直肠癌细胞系中表达上调,从而影响其相关标志物Claudin-4、E-钙粘素(E-cd)和波形蛋白(Vim)的表达。本实验用对EMT有抑制作用的SB431542和U0126EtOH处理HCT-116和HCT-8。两种抑制剂对结直肠癌细胞的EMT标志物和VM的形成均有显著影响。此外,HIF-1α在Hct-116细胞中的敲除也抑制了它们的VM能力。我们的研究揭示了HIF-1α在VM中的调节作用,并提示靶向HIF-1α或EMT可能是消除结直肠癌转移的有价值的策略。
Vasculogenic mimicry (VM) plays an important role in colorectal cancer (CRC) metastasis, and both hypoxia and the epithelial-mesenchymal transition (EMT) are necessary for VM. In this study, HIF-1α expression was upregulated in the VM-positive CRC cell line HCT-116 and thereby affected the expression of the EMT-related markers Claudin-4, E-cadherin (E-cd) and Vimentin(VIM). SB431542 and U0126EtOH, which can inhibit of EMT were used to treat HCT-116 and HCT-8 in these experiments. Both of the inhibitors had significant effect on EMT markers and the formations of VM in CRC cells. In addition, knockdown of HIF-1α in the HCT-116 cells inhibited their capacity for VM. Our study reveals a regulatory role for HIF-1α in VM and suggests that targeting either HIF-1α or EMT may be a valuable strategy for the elimination of CRC metastasis.
