Description
Sources: https://www.ncbi.nlm.nih.gov/pubmed/30913493 | https://www.ncbi.nlm.nih.gov/pubmed/21208908 | https://www.ncbi.nlm.nih.gov/pubmed/14977846 | https://www.ncbi.nlm.nih.gov/pubmed/12414636

E-7820 is a novel angiogenesis inhibitor. It inhibited in vitro proliferation and tube formation of human umbilical vascular endothelial cell (HUVEC). E-7820 decreased integrin alpha 2, 3, 5, and beta 1 in confluent culture of HUVEC, and integrin alpha 2 was initially suppressed in mRNA level, followed by decrement of integrins alpha 3, 5, and beta 1. Up-regulation of integrin alpha2 by phorbol 12-myristate 13-acetate abrogated the inhibitory effect of E7820 on tube formation within type I collagen gel, whereas addition of antibody against integrin alpha2 canceled the phorbol 12-myristate 13-acetate effect. This finding may provide the basis for a new approach to antiangiogenic therapy through the suppression of integrin alpha2 on endothelium. E-7820 showed a broad-spectrum antitumor effect in mice through inhibition of angiogenesis and indicate that the decrease of integrin alpha2 on platelets might serve as a biological marker for the antitumor efficacy of E-7820. Combining E-7820 and chemotherapeutic agents to block the integrin α2β1/PI3K/AKT/Snail signaling pathway revealed dramatically enhanced tumor suppression and provided an innovative approach for clinical colorectal cancer treatment.
