Abstract

Vasculogenic mimicry (VM) formation by cancer cells is known to play a crucial role in tumor progression, but its detailed mechanism is unclear. In the present study, we focused on integrin β1 (ITGB1) and assessed the role of ITGB1 in VM formation. We used in vitro methods to seed cancer cells on Matrigel to evaluate the capability of VM formation. We carried out ITGB1 gene deletion using the CRISPR/Cas9 system, and these ITGB1-knockout cells did not show a VM-like network formation. Further, reintroduction of ITGB1 rescued VM-like network formation in ITGB1-knockout cells. In conclusion, ITGB1 is a critical factor in VM of human cancer cells, and inhibition of ITGB1 may be a novel therapeutic approach for malignant cancer.

摘要

血管生成拟态(VM)的形成被认为在肿瘤进展中起着关键作用,但它的详细机制尚不清楚。在本研究中,我们专注于整合素β1(ITGB1),并评估了 ITGB1 在 VM 形成中的作用。我们使用体外方法在 Matrigel 上接种癌细胞,以评估 VM 形成的能力。我们使用 CRISPR/Cas9 系统进行 ITGB1 基因缺失,这些 ITGB1 敲除细胞没有表现出 VM 样网络形成。此外,在 ITGB1 敲除细胞中重新引入 ITGB1 挽救了 VM 样网络形成。总之,ITGB1 是人类癌细胞 VM 的关键因素,抑制 ITGB1 可能是恶性癌症的一种新的治疗方法。
