The regulatory network of miR-141 in the inhibition of angiogenesis

In this study, we used several in vitro and in vivo models to demonstrate that miR-141 in endothelial cells inhibits angiogenesis. Additional mechanistic studies showed that miR-141 suppresses angiogenesis through multiple targets, includingNRP1, GAB1, CXCL12 β, TGFβ2, andGATA6, and bioinformatics analysis indicated that miR-141 and its targets comprise a powerful and precise regulatory network to modulate angiogenesis. Taken together, these data not only demonstrate an anti-angiogenic effect of miR-141, further strengthening the critical role of miR-200 family in the process of angiogenesis, but also provides a valuable cancer therapeutic target to control both angiogenesis and EMT, two essential steps in tumor growth and metastasis.
